kamailio with external database to replace from uri
by Thibault Gueslin 14 Mar '16

14 Mar '16

I am using kamailio without database. It works fine. For some scenario, I would like to replace the from uri (using mac_replace_from works fine) but using data I can accessed with a REST API. I want to have different origination depending on the sipusername. I need to have some synchronous request. Have someone already these type of behaviour ? Regards Thibault

I have now spent some time to reproduce the issue. First of all: I had to adapt module reg_mod.c in ims_registrar_pcscf, because it containes a hardcoded P-CSCF address: str pcscf_uri = str_init("sip:pcscf.ims.smilecoms.com:4060"); which is only valid for smilecoms. Did you also change that? Then I got exactly the same problem. I found that the P-CSCF config causes in the part "# Check for Subsequent requests:" a reject " sl_send_reply("404","Not here");" I have doubts that this is correctly designed and have to dig deeper into the logic of the config-file. Fact is: the NOTIFY request does not contain a Route header and as it not an ACK it goes straight to the reject. Maybe any IMS expert can shed some light on this code as shown below: # Check for Subsequent requests: if (has_totag()) { # sequential request withing a dialog should # take the path determined by record-routing if (loose_route()) { if ($route_uri =~ "sip:mo@.*") { setflag(FLT_MO); } if(!isdsturiset()) { handle_ruri_alias(); } # RTP-Relay, if necessary route(RTPPROXY); t_relay(); } else { if ( is_method("ACK") ) { if ( t_check_trans() ) { # no loose-route, but stateful ACK; # must be an ACK after a 487 # or e.g. 404 from upstream server t_relay(); exit; } else { # ACK without matching transaction ... ignore and discard exit; } } sl_send_reply("404","Not here"); } exit; BR Franz

UDP send: Operation not permitted

Hi, we have a load balancer which is handling a lot of SIP traffic all day. There's always 20-40 Mbit SIP traffic going through. From time to time we see in our logs messages like these: Sep 16 09:46:28 ecker /usr/sbin/kamailio[25505]: ERROR: <core> [udp_server.c:591]: udp_send(): ERROR: udp_send: sendto(sock,0x7f2d9d6b3ce0,1321,0,46.237.225.126:5060,16): Operation not permitted(1) Sep 16 09:46:38 ecker /usr/sbin/kamailio[25194]: ERROR: <core> [udp_server.c:591]: udp_send(): ERROR: udp_send: sendto(sock,0x7efc982b8fc8,420,0,82.113.121.183:35794,16): Operation not permitted(1) Sep 16 09:46:40 ecker /usr/sbin/kamailio[25505]: ERROR: <core> [udp_server.c:591]: udp_send(): ERROR: udp_send: sendto(sock,0x7f2d9d6b3ce0,1338,0,5.158.137.9:55067,16): Operation not permitted(1) Sep 16 09:46:44 ecker /usr/sbin/kamailio[25183]: ERROR: <core> [udp_server.c:591]: udp_send(): ERROR: udp_send: sendto(sock,0x7efc982d9f48,450,0,178.165.131.197:37515,16): Operation not permitted(1) Sep 16 09:46:49 ecker /usr/sbin/kamailio[25643]: ERROR: <core> [udp_server.c:591]: udp_send(): ERROR: udp_send: sendto(sock,0x7f93fb624530,496,0,172.56.7.69:25643,16): Operation not permitted(1) Sep 16 09:46:55 ecker /usr/sbin/kamailio[25335]: ERROR: <core> [udp_server.c:591]: udp_send(): ERROR: udp_send: sendto(sock,0x7f41632cda98,598,0,80.215.234.139:3396,16): Operation not permitted(1) Sep 16 09:46:56 ecker /usr/sbin/kamailio[25345]: ERROR: <core> [udp_server.c:591]: udp_send(): ERROR: udp_send: sendto(sock,0x7f41632f4840,459,0,94.197.120.191:8225,16): Operation not permitted(1) I know that these messages can be produced by iptables blocking the outbound traffic.

Has anyone ever seen this? It looks like a load thing, because at weekends there are significantly less errors. Thanks, Sebastian

SIP Autentication Failed
by Bruno Henrique Gomes Gouvêa 11 Mar '16

11 Mar '16

Hello, First excuse any mistakes in English. I'm working on a platform that makes use of integrated Kamailio with asterisk (Elastix mt). This platform allows the login of my SIP clients via the extension number and the client's domain, where the kamailio after authentication change the username to sip EXTENSION + _ + DOMAIN (expected by Asterisk) and sends to the asterisk. I need the client can also send the sip user in standard EXTENSION + _ + DOMAIN, for it changed the view subscriber to also return a username record in the format that the softphone is sending, but the platform still seems not authenticate the REGISTER using new way functions in auth_check ("$ FD", "subscriber", "0") and auth_challenge ("$ FD", "0"). Thus works: Login: 101 Domain/server: pabx999999.ligou.me Password: PASSWORD_PLAIN This way does not work: Login: 101_pabx999999.ligou.me Domain/server: pabx999999.ligou.me Password: PASSWORD_PLAIN Already got a good look at the documentation and could not find the problem, could give me some help?

rare impossibility to send requests to TLS connected peer
by Vasiliy Ganchev 09 Mar '16

09 Mar '16

Hi folk! Have a rare issue with tls connections. Have a server with 100+ active tls connections, that are connected to separate TCP proxy, that listen on port 443. TCP proxy send sip traffic to Kamailio via localhost:5061. In this way all connections in Kamailio are considered from Localhost. Issue scheme: - UA-A (sip-phone, UDP/TCP/TLS) -> call -> sip server (Kamailio+Asterisk based) -> UA-B (sip phone, transport=TLS) - The troubles happened in part of flow to UA-B: --- kamailio script make lookup(location), find AOR for UA-B (here is OK) --- after t_relay, kamailio make branch_route logic and try to send INVITE to tcp socket --- HERE IS the trouble: connection seems to be opened, but Kamailio cannot send INVITE there (say: no open tcp connection found) --- Kamailio try to open tcp connection from itself, TCP proxy refuse it --- as a result - Kamailio answer 477 to Asterisk, and finish processing debug level 3 logs (from the point where Kamailio try to send INVITE in opened connection) Jan 25 14:32:43 /usr/sbin/kamailio[4722]: DEBUG: <core> [tcp_main.c:1463]: _tcpconn_find(): tcpconn_find: 0 port 60286 Jan 25 14:32:43 /usr/sbin/kamailio[4722]: DEBUG: <core> [ip_addr.c:243]: print_ip(): tcpconn_find: ip 127.0.0.1 Jan 25 14:32:43 /usr/sbin/kamailio[4722]: DEBUG: <core> [tcp_main.c:1820]: tcp_send(): tcp_send: no open tcp connection found, opening new one Jan 25 14:32:43 /usr/sbin/kamailio[4722]: DEBUG: <core> [ip_addr.c:243]: print_ip(): tcpconn_new: new tcp connection: 127.0.0.1 Jan 25 14:32:43 /usr/sbin/kamailio[4722]: DEBUG: <core> [tcp_main.c:1073]: tcpconn_new(): tcpconn_new: on port 60286, type 3 Jan 25 14:32:43 /usr/sbin/kamailio[4722]: DEBUG: <core> [tcp_main.c:1626]: _tcpconn_add_alias_unsafe(): _tcpconn_add_alias_unsafe: alias port 60286 for hash 2646, id 404319 Jan 25 14:32:43 /usr/sbin/kamailio[4722]: DEBUG: <core> [tcp_main.c:1626]: _tcpconn_add_alias_unsafe(): _tcpconn_add_alias_unsafe: alias port 60286 for hash 2728, id 404319 Jan 25 14:32:43 /usr/sbin/kamailio[4722]: DEBUG: <core> [tcp_main.c:1624]: _tcpconn_add_alias_unsafe(): _tcpconn_add_alias_unsafe: alias already present Jan 25 14:32:43 /usr/sbin/kamailio[4722]: DEBUG: <core> [tcp_main.c:1382]: tcpconn_add(): tcpconn_add: hashes: 2646:2728:0, 863 Jan 25 14:32:43 /usr/sbin/kamailio[4722]: DEBUG: tls [tls_server.c:184]: tls_complete_init(): Using TLS domain TLSc<default> Jan 25 14:32:43 /usr/sbin/kamailio[4722]: DEBUG: tls [tls_domain.c:700]: sr_ssl_ctx_info_callback(): SSL handshake started Jan 25 14:32:43 /usr/sbin/kamailio[4722]: ERROR: <core> [tcp_main.c:2742]: tcpconn_1st_send(): connect 127.0.0.1:60286 failed (RST) Connection refused Jan 25 14:32:43 /usr/sbin/kamailio[4722]: ERROR: <core> [tcp_main.c:2752]: tcpconn_1st_send(): 127.0.0.1:60286: connect & send for 0xb1d3b7e8 failed: Connection refused (111) Jan 25 14:32:43 /usr/sbin/kamailio[4722]: DEBUG: <core> [tcp_main.c:2947]: tcpconn_chld_put(): tcpconn_chld_put: destroying connection 0xb1d3b7e8 (404319, -1) flags 0060 Jan 25 14:32:43 /usr/sbin/kamailio[4722]: ERROR: tm [../../forward.h:247]: msg_send(): tcp_send failed Jan 25 14:32:43 /usr/sbin/kamailio[4722]: DEBUG: tm [t_fwd.c:1591]: t_send_branch(): t_send_branch: send to 127.0.0.1:60286 (3) failed Jan 25 14:32:43 /usr/sbin/kamailio[4722]: WARNING: tm [t_fwd.c:1610]: t_send_branch(): ERROR: t_send_branch: sending request on branch 0 failed Jan 25 14:32:43 /usr/sbin/kamailio[4722]: DEBUG: tm [t_funcs.c:358]: t_relay_to(): ERROR:tm:t_relay_to: t_forward_nonack returned error Jan 25 14:32:43 /usr/sbin/kamailio[4722]: DEBUG: tm [t_funcs.c:375]: t_relay_to(): -477 error reply generation delayed Jan 25 14:32:43 /usr/sbin/kamailio[4722]: DEBUG: tm [t_lookup.c:1526]: t_unref(): t_unref: delayed error reply generation(-477) Jan 25 14:32:43 /usr/sbin/kamailio[4722]: DEBUG: <core> [parser/msg_parser.c:339]: parse_headers(): parse_headers: flags=ffffffffffffffff Jan 25 14:32:43 /usr/sbin/kamailio[4722]: DEBUG: tm [t_reply.c:1670]: cleanup_uac_timers(): DEBUG: cleanup_uac_timers: RETR/FR timers reset Jan 25 14:32:43 /usr/sbin/kamailio[4722]: DEBUG: tm [t_reply.c:728]: _reply_light(): DEBUG: reply sent out. buf=0xb67c000c: SIP/2.0 477 Unfortun..., shmem=0xb1b676cc: SIP/2.0 477 Unfortun Jan 25 14:32:43 /usr/sbin/kamailio[4722]: DEBUG: tm [t_funcs.c:156]: put_on_wait(): DEBUG: put on WAIT Jan 25 14:32:43 /usr/sbin/kamailio[4722]: DEBUG: tm [t_reply.c:738]: _reply_light(): DEBUG: _reply_light: finished Additionally want to say, that suddenly we don't have clear reproduce, it happened only on 2 production servers, what are common conditions for issue: - transport=TLS - when issued call is done, I checked with netstat, the connection is alive - the issued device is re-REGISTERed as usual, in kamctl ul show I see registration before/during/after issued call - issue appear only when connection through our custom TCP proxy :443 (to Kamailio it is from 127.0.0.1:5061) - if connection switched to Kamailio 5061 directly - issue never (till now) reproduced - in one of the issued server - I noticed big number of tcp id.

Branching v4.4
by Daniel-Constantin Mierla 09 Mar '16

09 Mar '16

Hello, I am considering to branch v4.4 latest on March 10, after that the master branch can be used again for adding new features and fixes will be backported to branch 4.4. If it proves to worth branching earlier, it can be done. As an estimate date for the release of v4.4.0, a good candidate would be one of the days between March 22, 23 or 24. Any other suggestions or comments? Cheers, Daniel -- Daniel-Constantin Mierla http://twitter.com/#!/miconda - http://www.linkedin.com/in/miconda Kamailio Advanced Training, Berlin, March 7-9, 2016 - http://www.asipto.com

Kamailio 5.0 - Scripted DB Migrations
by Tim Chubb 08 Mar '16

08 Mar '16

As a suggestion for 5.0 having a scripted DB migration system would make upgrading much easier. Something like what Asterisk now uses (Alembic https://pypi.python.org/pypi/alembic) would be ideal, as it works in a DB agnostic manner and you would just have to ensure that there is a driver for the DB you wish to use. That way you would just update the definition script and select the target when you run the updater, and would allow kamailio a greater choice in backing DB's as once the script is written assuming a driver is available for you RDBMS the schema would be successfully ported. This would do away with maintaining separate MySQL, Postgres, Oracle, MSSQL scripts as well. The only issue I can think with a system like this is in the situation where hardcoded SQL strings are in the source and use a RDBMS specific function as that could cause some "fun" in debugging...

Kamailio design that needs one b2bua
by anthony gonzalez 08 Mar '16

08 Mar '16

Hello there, I'm designing and implementing a kamailio solution for sip routing between several softswitch based on prefixes. IIn this setup i will need an b2bua in order to do topology hiding and also to make transparent the call transfer between phones registered in kamailio and softswitches(that doesn't support very well REFER messages). I was searching what solution should I use and I found 3 opensource solutions that for me seems to be acceptable: Sems. Freeswitch. Opensips with module b2bua. Based on your experience and contemplating the stability, performance and support, what is the solution that you advice me ? Thank you for you time. Anthony

Hi, a suggestion for Kamailio 5.0 is to get rid of the cryptic, case sensitive pseudo-variable names. Instead we replace them with descriptive names like the ones already provided by the TLS module. The current pseudo variables are a constant nuisance unless you deal with Kamailio every day and know them all by heart. They are an unnecessary barrier for new users learning Kamailio and force you to refer to the documentation more often than necessary. Ideally there would be a script to replace old variable names in configuration files with the new ones to make the transition less painful. -Sven

How to get Authorization Attributes
by Matthew Harrold 07 Mar '16

07 Mar '16

Hi All, I am trying to get attributes from the Proxy-Authenticate WWW-Authenticate and Authorization headers, namely username, realm, uri, nonce, and response, I can see some of these are already presented as psuedo-variables, however nonce and response are not. What's the most efficient way to obtain these headers? I'm currently using a regex, but there must be a more efficient method. Thanks for your help, Matthew

Re: [SR-Users] KAMAILIO Installation Problem
by Ed Todd 05 Mar '16

KAMAILIO Installation Problem Fred: re confusion. A few more details. Site 1 is a development site. The project in question is VoIP, using ANTISIP. A Windows server application is monitoring activities and carrying out local functions via IPhones. It has a LAN with static IPs for: · Windows 10 PC used for development · Windows 10 laptop, used for testing · MACBOOK, used for IPhone development · ‘Other PC’, recently converted to Linux + KAMailIO, using the binaries installation route rather than the source code route. It has a Comcast Modem/Router, Cisco DPC3941B Site 2 is a business site, which demonstrates the application using its own Windows PC and IPhones. It does not have any static IPs. Each site uses IPhones as the user interface of this application, via cell or WIFI. Both sites can communicate via SIP.ANTISIP.COM Site 1 can communicate with site 1 KAMAILIO but site 2 cannot: timeouts occur. I just installed what seems like a standard package: · Debian 32 or 64 bit graphical · Apt-get install git gcc make flex bison mysql-server kamailio-mysql-modules kamailio-tls-modules kamailio Should be OK so far apart from the .COM name of the Linux box. I then updated files as described earlier and the problems start. Apart from changing a few constants, I have not altered any script, I am just using the standard one shipped in the package above. I’ve had to guess how to tell KAMailIO about the static IP.

KAMAILIO Installation Problem
by Ed Todd 05 Mar '16

05 Mar '16

I have a local area network with: · A Windows PC with a VOIP application · A Linux PC with KAMailIO There is also a remote Windows PC with the same VOIP application. There is also an IPhone VOIP application that communicates with the Windows PC application. All communications use the same KAMailIO system. The IPhone application communicates with the PC on the local network. It times out trying to communicate. I have tried a URL and a static IP address for SIP_DOMAIN, neither succeeds. Here are some extracts from the log (ignore timestamp gap, several calls were attempted). I think the problem is that the reply to the PC is being sent to 192.168.1.12 instead of 92.13.147.87.

DMQ question
by Alex Balashov 04 Mar '16

04 Mar '16

Hi, If I understand the DMQ documentation correctly, when a SIP request is distributed to other Kamailio instances via dmq_t_replicate(), it is not merely sent as a payload in a novel way, but actually "rehydrated" by the receiver into a mock request on the other end and processed as through it were a "real" message that came into the request_route[] in the natural way. Is this an accurate assumption? -- Alex -- Alex Balashov | Principal | Evariste Systems LLC 303 Perimeter Center North, Suite 300 Atlanta, GA 30346 United States Tel: +1-800-250-5920 (toll-free) / +1-678-954-0671 (direct) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/

options_reply() - ruri contains username
by Alex Balashov 04 Mar '16

04 Mar '16

Hello, This may have been discussed before, but when options_reply() from the siputils module is used to respond to OPTIONS requests and those OPTIONS requests come in with an RURI containing a user part, the following error is emitted to the logs: LM_ERR("ruri contains username\n"); No reply for the OPTIONS ping is given in this scenario. OPTIONS pings against a username are very common, and I can find no justification for this check in my interpretation of RFC 3261 scripture. According to Section 11.1 ("Construction of an OPTIONS request"): An OPTIONS request is constructed using the standard rules for a SIP request as discussed in Section 8.1.1. Moreover, the example request line given in that very section is: OPTIONS sip:carol@chicago.com SIP/2.0 Might it perhaps be agreeable to remove this constraint? Or is there some rationale for its presence that I have simply failed to grasp? Thanks! -- Alex -- Alex Balashov | Principal | Evariste Systems LLC 303 Perimeter Center North, Suite 300 Atlanta, GA 30346 United States Tel: +1-800-250-5920 (toll-free) / +1-678-954-0671 (direct) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/

mariadb and sql_query_async: the db driver module doesn't support async query
by Daniel Tryba 03 Mar '16

So trying to push some inserts/updates to the background I added: async_workers=1 and replaced sql_xquery("ca", "$var(query)", "ra"); sql_result_free("ra"); with sql_query_async("ca", "$var(query)"); where: $var(query)="insert into CDR.callogs (accountcode,number) values ('"+$var(accountcode)+"',substring('"+$rU+"',1,4))"; Only to find out that the queries aren't inserted and the log contains: /usr/sbin/kamailio[24754]: ERROR: sqlops [sql_api.c:429]: sql_do_query_async(): the db driver module doesn't support async query The table is an InnoDB some insert delayed should give these kind of errors, but isn't the point of sql_query_async that it does the plain normal insert in a background task?

If the backends for a dbcluster supports sql_query_async, sql_query_async should be available. At this moment (only tested with 4.3.x) async isn't supported.

Kamailio 5.0 - HTTP loading of config files
by Tim Chubb 03 Mar '16

03 Mar '16

As a suggestion for 5.0 being able to load config files from a URL, with any includes being taken relative to the URL would be a really handy feature. It would allow a central source for config files in a cluster and make it a much simpler process to push out changes to routing to all nodes.

Kamailio as a front-end proxy
by Anton Tonev 02 Mar '16

02 Mar '16

Hello everybody, I am a new user of Kamailio (4.3.1), I am working with it since 1-2 months. The thing that I'm trying to do is to build the following system: same LAN 192.168.0.1 Alice proprietary SIP Server [Public_IP_X] ------------ [Public_IP_Y] Kamailio [172.26.0.1] ---------- [172.26.0.1] with 192.168.0.1 registrar Bob Obviously Kamailio has to translate the local addresses of Alice and Bob, e.g. to use the Nathelper module. The module is doing well its job because the Contact headers are replaced with the Public_IP_X when a REGISTER message is sent by Alice's or Bob's sip phones (I am using Linphone and Zoiper as clients). Once the incoming sip register was treated by Kamailio it is sent to the proprietary SIP Server. The server sends 200 OK to Kamailio and the proxy relays the message to the clients. So the sip registration for me it is OK. But when it comes to initiate a call from Alice to Bob the things are not as I expect it. The initial request INVITE sent from Alice goes to the sip server but then the server instead of sending the INVITE for Bob through Kamailio, it sends the message directly to Bob's device. Does anyone knows how to "tell" to the sip server, using the SIP protocol, that it must use the proxy? The only thing I have in mind is to force Kamailio to replace the contact of Alice and more precisely the host/ip address by the proxy's host/ip address. I tested this idea and the sip server did what I was expecting but for me this is not a proper solution. To do that I used this discussion - http://opensips.org/pipermail/users/2010-October/014873.html Thank you in advance for your attention ! Best regards, Anton

Fwd: [kamailio]: Querie on ratelimit module
by Prashant Desai 02 Mar '16

02 Mar '16

Hi Kamailio, We are using Kamailio V4.2.3 for our project and we are trying to address the performance requirement. We have following queries and need some inputs from Kamailio. *Requirement :* CPU Utilization Limit to 70%, If the limit is crossed Kamailio has to reject the Request. And If it is within the limit Kamailio has to Process the Requests. (i.e. Kamailio has to dynamically set and reset the policy based on CPU Load). *Our Findings* : We have come across ratelimit module in Kamailio, we tried using the same to address the requirement but we see it is not dynamically setting and resetting the policy (once if it starts rejecting then every time it rejects it, only if we restart the kamailo it works) *What we Need*: We need to know 1. Are we using the right module to address the above requirement ? 2. We are only using ratelimit, module, do we have to include any other module along with ratelimit? 3. We are using FEEDBACK algorithm, is that OK ? 4. Setting “ modparam("ratelimit", "pipe", "3:FEEDBACK:70") “ , is this correct ? 5. In ratelimit.c , function static int pipe_push(struct sip_msg * msg, int id) { *case* *PIPE_ALGO_FEEDBACK*: *LM_DBG(**"drop_rate [%d],hash[*pipes[id].counter][%d]\n"**,*drop_rate, hash[*pipes[id].* *counter**])*; ret = (hash[*pipes[id].counter % 100] < *drop_rate) ? -1 : 1; } We are not able to understand the above line ( hash[*pipes[id].counter % 100]). Could you please elaborate. 6. Where are we lagging ?

RFC: Kamailio 5.0
by Daniel-Constantin Mierla 01 Mar '16

01 Mar '16

Hello, at Fosdem and other events this year, while meeting many of Kamailio devs, the topic of what's next for Kamailio came into discussions, with suggestions that after 4.4 it may be time for some major leap to 5.0. I created a page where I collected the main ideas put on table so far - rather unpolished draft, but eventually a good starting point: * https://www.kamailio.org/wiki/devel/kamailio-5.0-design Everyone is invited to add suggestions to the wiki page and/or discuss here on mailing lists, what should be there in 5.0, what is good (to keep) or bad (to remove) with current version, what is missing and it is "must have", ... Not to have a single long tread, for each new idea, start a new email thread with subject prefixed by Kamailio 5.0. I think this impacts users, not only devs, and their contribution is useful as well, so it should be fine to discuss the ideas/concepts on sr-users. When it gets to real implementation discussions, then it can be on sr-dev. Cheers, Daniel -- Daniel-Constantin Mierla http://twitter.com/#!/miconda - http://www.linkedin.com/in/miconda Kamailio Advanced Training, Berlin, March 7-9, 2016 - http://www.asipto.com

catching lost websocket ua
by Juha Heinanen 01 Mar '16

01 Mar '16

I have done some more digging on websocket:closed event route. In DB_ONLY mode, easy deregistration of a websocket UA at connection close would require access in the event route to connection_id of the closed connection. The function that is run at the close has ws_connection_t argument: static void wsconn_run_route(ws_connection_t *wsc) ws_connection_t record has these two fields: int id; /* id and id_hash are identical to the values */ unsigned id_hash; /* for the corresponding TCP/TLS connection */ Is id the same thing as what is stored in connection_id field of location table? If it is, may be its value could be made available to the event route in a pseudo variable. -- Juha

Help

Hi, I work for a VOIP service provider, and have been tasked with optimizing our infrastructure. We have been providing VOIP services to our clients via Asterisk VMs (PIAF) in an ESXi environment, hosted in a datacenter. We are looking for some kind of SIP Router, which would authenticate clients and route their SIP traffic to the appropriate server. By doing so, we are hoping to further secure our infrastructure and to possibly have only one Public IP (which would resolve to the Private IP of the SIP router). The Asterisk servers serve IVR/RINGGROUPS/OUTBOUNDTRUNKS/INBOUNDROUTES/OUTBOUNDROUTES. The Sip Router would therefore route all SIP traffic between the phones and the Asterisk servers, ad the phones would register to the SIP Router. I have tried many solutions (Kamailio, OpenSER, siproxd, Brekeke), but have not been able to configure these services to work the way we want them to. I am including a chart along with this email to outline what we would like to accomplish. Any suggestions or guides would be immensely appreciated. Thank you all for your time.

Hi, Sorry, but I just want to know the meaning of "shmized", I can't find it in the dictionary, thank you very much. typedef struct _cfg_group { int num; /*!< number of variables within the group */ cfg_mapping_t *mapping; /*!< describes the mapping betweeen the cfg variable definition and the memory block */ char *vars; /*!< pointer to the memory block where the values are stored -- used only before the config is shmized. */ -- Best Regards, Shengy

want to go mobile, common issues ?
by Sébastien Brice 27 Feb '16

27 Feb '16

Hi everyone. I have enjoyed talk about realtime of last FOSDEM, talk about K. was good. I want to know how do you solve sip dialogs with mobile? actually I know REGISTER is important to authenticate and this request generally last 1hour until then you have to register again. How to solve that for mobile telephony (and what about idle) ? do cellular phone use this schema ? you have to go UDP ? does TCP comes better to handle mobile telephony? I want to ask about IMS as well :-) I heard many good things about Image Multimedia Systems, but in concrete terms what is it? Does IMS target mobile only ? i heard about Boghe, it has many more parameters regarding DNS SRV and extra options. What's so different from my traditionnal Linphone ? thx you

ims_qos module support IPv6 address?
by Ayon Pal 26 Feb '16

26 Feb '16

Hi, I have been recently configuring kamailio IMS (v 4.3.4) for IPv6 user registration. I have my PCSCF Gm interface, ICSCF Mw interface and SCSF Mw interface all listening on IPv6 address on port 5060. PCSCF Rx interface is configured with IPv4 address to communicate with PCRF. Similarly ICSCF and SCSCF are also configured with IPv4 address to communicate with HSS (not Fraunhofer HSS) . My Linphone client configured with IPv6 address is sending register message to PCSCF. PCSCF throws the following error on while sending the AAR to PCRF *ubuntu kamailio[22627]: INFO: <script>: REGISTER (sip:001010000000004@TestNetwork (5555:0:0:1:ABCD:0:0:1:9060) to sip:001010000000004@TestNetwork, KFEtBsO-dm)ubuntu kamailio[22627]: ERROR: ims_qos [rx_aar.c:878]: rx_send_aar_register(): Unable to add framed IP AVPubuntu kamailio[22627]: ERROR: ims_qos [rx_aar.c:904]: rx_send_aar_register(): unexpected errorubuntu kamailio[22627]: ERROR: ims_qos [mod.c:1145]: w_rx_aar_register(): Failed to send AARubuntu kamailio[22627]: ERROR: ims_qos [mod.c:1189]: w_rx_aar_register(): Error trying to send AARubuntu kamailio[22627]: WARNING: tm [t_lookup.c:1476]: t_unref(): WARNING: script writer didn't release transaction* On debugging, I found that the ip version is hard coded to AF_INET.( a comment is also written TODO: IPV6 support) in ims_qos/mod.c file.

So, I would like to know if ims_qos module supports IPv6 address ? Regards, Ayon

Media server can't return ACK correctly
by Alexandru Covalschi 26 Feb '16

26 Feb '16

Hello everyone. The setup is: Carrier ip is CARRIER_IP Public network Kamailio IP will be PUBLIC_IP Private network Kamailio IP will be KAMAILIO_PRIVATE_IP Private network Freeswitch IP is FREESWITCH_PRIVATE_IP ACK CARRIER_IP -> PUBLIC_IP->FREESWITCH_PRIVATE_IP And freeswitch tries to actually send ACK back to PUBLIC_IP which he can't access. Kamailio trace: http://pastebin.com/raw/1W1sXuUa Freeswitch trace: http://pastebin.com/raw/KkZCwTTJ request_route: http://pastebin.com/raw/Y17pXUGY NATMANAGE route: http://pastebin.com/raw/0BpPDjN0 WITHINDLG route: http://pastebin.com/raw/5LpwSigF I'm seeking help with that - what parameter I need to change/add to solve that?

[4.2.6] Keep-alive sent by dialog module seems does not refresh the dialog...
by Jack Wang 26 Feb '16

26 Feb '16

Hello, I used the below settings to test the keep-alive function within a dialog: modparam("dialog", "default_timeout", 60) modparam("dialog", "ka_timer", 10) modparam("dialog", "ka_interval", 30) and use dlg_set_property("ka-src") or dlg_set_property("ka-dst") to send OPTIONS to caller or callee. A few questions to ask: (1) What's the difference between ka_timer and ka_interval? I read the http://www.kamailio.org/docs/modules/4.2.x/modules/dialog.html , but still can not understand very clearly. I know the ka_interval means OPTIONS will be sent after 30 seconds when dialog started or last keep-alive has been done. but I don't know how ka_timer works. (2) From the packets captured I can see server sent OPTIONS and the client (caller or callee) sent back 200 OK. According to the document, "The dialog timeout is reset each time a sequential request is processed" However, the dialog was still timeout, it seems that the timeout value was not reset. And I make the clients send the OPTIONS and frequently , the dialog never expires now. So the refresh only works on the keep-alive sent by clients not the server here? Thanks :)

Binary interface: usrloc replications - restore registrations after node restart
by evoip＠ukr.net 25 Feb '16

25 Feb '16

Hi ! It's really nice option - that now Opensips nodes can replicate "SIP registrations" and "Dialogs" between each other w *"bin_listen" options. http://www.opensips.org/Documentation/Interface-Binary-2-1 * I have a few question related to cluster architecture with fail over: 1). - If one of the "Opensips phone edges" was restarted - can it catch all USRLOC registrations throught binary interface from alive nodes ? - if it can't do restoring of the database through binary interface - maybe you have an idea how to do that ? 2). - it's share dialogs information - if one node is suddenly down, can call dialog be proceeded on other node ? With kind regards, Ewgeny Berladin Voip Engineer

how to drop 200ok and survive?
by Uri Shacked 25 Feb '16

25 Feb '16

Hi, for some strange reason, ask my regulator.... i need to manipulate certain calls. the scenario goes like this: 1. caller sends invite to kamailio. 2. kamailio transfer the call to asterisk. 3. asterisk send progress and play "hello". 4. asterisk creates a new call (dial) to the same kamailio with destination callee. 5. the callee answers the call. here, i need to block the 200ok. so that the caller does not receive it. i managed to block it with t_suspend(). but, there is no bidirectional media. the 183 progress was sent with sendreceive. it seems the asterisk is waiting for the ACK in order to open both ways for media. i tried to use uac_send_req() but it is being sent with no to tag. and when i try manipulating the uac_req(turi) it does not help because it takes all the string i entered and wraps it with <>. any ideas? BR, Uri

Hi guys, I am currently doing research in SIP security. As described in RFC 6072, there can be credential server storing public and private keys (certificates). I have question, if there is any support from Kamailio for this, or if somebody has tried similar things with Kamailio. Thanks! Best regards Marek Moravcik

Can not start kamailio 4.3 and 4.4. Fork errors with working configuration.
by Yuriy Gorlichenko 25 Feb '16

Checked config at another servers instanses. I tried to start 2 workable configs. All starts ends with 3 type of errors error.log error2.log error3.log Debug outputs of 3 times started one config on one same server. I think error outside kamailio because 4.3 and 4.4 also compiled successfully. But at this time I can not understand where is trouble. In first file I see that kamailio can not connect to database but user/pass is correct, and I also see that kamailio can not make fork of process. 2 and 3 process have different troubles but base is one - can not fork.

ovh trunk
by Sébastien Brice 24 Feb '16

24 Feb '16

Hi everyone I followed this guide http://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb and got it working (101, 102 and 103) can call eachother. But now i am trying to figure Asterisk's role out. I am more an ipbx person and i am used to register providers trunk in asterisk/sip.conf file, like this: register => [peer?][transport://]user[@domain][:secret[:authuser]]@host[:port][/extension] doing that i got plenty of OPTIONS request and 200 OK reply between my Kamailio and my provider (and it is a bit noisy) doing that i feel missing kamailio's logic and power to deal with externals trunk provider The thing is i need my authenticated users (101,102,103) be capable dialing my trunk and requesting INVITE for non-local request. What is the best way to achieve that? My DID provider gave me user/passwd/realm. I heard about avp special variables (auth_XXXX_avp and uac) and some snippets config that could help me to go there. Is that efficient to place the routing's logic to Kamailio and how to do that with my ovh trunk? thx you

DNSSRV to resolve to multiple Kamailio servers
by Derek Bolichowski 24 Feb '16

24 Feb '16

Hello, I'm trying to create a DNSSRV record that resolves to multiple Kamailio servers for my clients to authenticate against. Before using Kamailio, we had a DNSSRV record setup that resolved to our multiple Asterisk servers via their WAN Address. I've tried to do the same with Kamailio, but not having much luck. The DNSSRV record is setup as follows, as you can see from the output of a `dig` query: ;_sip._udp.kam.some-domain.com. IN SRV ;; ANSWER SECTION: _sip._udp.kam.some-domain.com. 14399 IN SRV 20 100 5060 kam1.some-domain.com. _sip._udp.kam.some-domain.com. 14399 IN SRV 10 100 5060 kam2.some-domain.com. I am not able to register any devices to this SRV record. However I /CAN/ register directly to kam1.some-domain.com and kam2.some-domain.com Registration attempts to the DNSSRV Record (kam.some-domain.com) do not even appear in /var/log/messages. We have the domain name for kam (SRV Record), kam1 and kam2 setup in kamailio.domain and kamailio.dispatcher. What am I missing here? Thank you for taking the time to read this! Derek Bolichowski

PUBLISH request receives 404 response, and loops on loopback interface
by Matthew Harrold 23 Feb '16

23 Feb '16

Hi all, I am new to Kamailio but have previous experience with Asterisk, Freeswitch and SIP. I am using a fairly default config file with some sections removed (E.G NAT) to simplify things, and some extra logging so I can see the way packets traverse the configuration. Config here - http://pastebin.com/raw/CCgT0C78 I have noticed that when a UAC sends a PUBLISH request, Kamailio immediately responds '404 Not Found' and more worryingly the logs and a packet capture running on the lo interface indicate it's sending the PUBLISH request to itself in a loop until it hits the Max-Forwards limit. Publish URI is PUBLISH sip:201@kamailio.marrold.co.uk;transport=UDP SIP/2.0 I have two questions, 1) Why is this request being sent a 404, when the UAC is in the USRLOC table? 2) Why is the request looping until Max Forwards is exhausted? Any help appreciated, Marrold

Installation issues
by Ed Todd 23 Feb '16

23 Feb '16

I tried installing the pre-compiled version of 4.3 under Debian and had all sorts of problems. I found there were 2 sets of paths involved in documentation/procedures plus a reference to a 3rd which caused a complete failure when the directory referred to was missing. I ran into more problems when I tried to access my server from outside my network (static IP). So I thought I’d bite the bullet and install from source. I get to the bit where I am creating the database and even more errors: a.. cannot connect to local mysql server b.. kamdbctl.mysql 112: unary operator expected In one part of the procedure it refers to db_mysql and another to mysql. Is there a simple installation guide around anywhere which will help me get around all these problems? All I want is a Debian with KAMAILIO running on it!

sip_trace vs uac_reg
by James Cloos 22 Feb '16

22 Feb '16

I've started adding sip_trace to my kamailios, and mostly have it working, but cannot figure out how to capture the outgoing calls from uac_reg. I had to add: reply_route { sip_trace(); } onsend_route { sip_trace(); } to capture those packets. What *_route {} does uac_reg target for its outgoing packets? I read uac_reg.[ch], and see that it uses the t_request method from tm's struct tm_binds. And that the methods are defined via a call to load_tm_api(), and that t_request defaults to the request() function in tm/uac.c. But I don't see from that which route chunk it uses. -JimC -- James Cloos <cloos(a)jhcloos.com> OpenPGP: 0x997A9F17ED7DAEA6

db_cluster.so module and kamctlrc DBHOST= field
by Derek Bolichowski 22 Feb '16

22 Feb '16

Hi there, New user to Kamailio here. We currently have it up and running in a virtualized environment with 1 Kamailio sever, 1 Asterisk server and 1 MySQL server. I'm currently writing install scripts to make deploying new nodes/servers easy and to keep settings the same across the board. I've chosed to load the db_cluster.so module in kamailio.cfg, as we will have 2x MySQL servers in master-master replication which will contain the 'kamailio' and 'asterisk' tables. I've just hit a stumbling block - in `kamctlrc`, there is a field called `DBHOST=`. How can I reference my cluster here? In kamailio.cfg, I simply define DBURL as "cluster//<clustername>". What is the syntax for 'DBHOST=' in 'kamctlrc'? Can I reference the cluster? Can I have 2 separate DBHOST= lines? Looking for some guidance on this one. Thanks, Derek B.

I have now spent some time to reproduce the issue. First of all: I had to adapt module reg_mod.c in ims_registrar_pcscf, because it containes a hardcoded P-CSCF address: str pcscf_uri = str_init("sip:pcscf.ims.smilecoms.com:4060"); which is only valid for smilecoms. Did you also change that? Then I got exactly the same problem. I found that the P-CSCF config causes in the part "# Check for Subsequent requests:" a reject " sl_send_reply("404","Not here");" I have doubts that this is correctly designed and have to dig deeper into the logic of the config-file. Fact is: the NOTIFY request does not contain a Route header and as it not an ACK it goes straight to the reject. Maybe any IMS expert can shed some light on this code as shown below: # Check for Subsequent requests: if (has_totag()) { # sequential request withing a dialog should # take the path determined by record-routing if (loose_route()) { if ($route_uri =~ "sip:mo@.*") { setflag(FLT_MO); } if(!isdsturiset()) { handle_ruri_alias(); } # RTP-Relay, if necessary route(RTPPROXY); t_relay(); } else { if ( is_method("ACK") ) { if ( t_check_trans() ) { # no loose-route, but stateful ACK; # must be an ACK after a 487 # or e.g. 404 from upstream server t_relay(); exit; } else { # ACK without matching transaction ... ignore and discard exit; } } sl_send_reply("404","Not here"); } exit; BR Franz

Make SIP session between two kamailio servers
by Cockhootec Yahrabee 21 Feb '16

21 Feb '16

Hi everyone, I am curious if there is a way to make SIP session between two kamailio server instances eg. if there is way to use kamailio as an SIP client and SIP server at the same time. I am thinking about the following configuration: kamailio main server ----- kamailio server B ----- SIP client B1 | | | kamailio server A ----- SIP client A2 | | | SIP client A1 I want to be able to make SIP session between: SIP client A1 : SIP client A2 kamailio server A : kamailio server B SIP client A1 : SIP client B1 (this would be great) If there is currently no way to do this do you think that it would be possible to create the module which will support this kind of functionality? Thanks in advance for the replies

Hi All, If the client is forcely closed, the client will be shown as online state in kamailio when I run the command: "kamctl online". How long will be the client online since client is closed? Thank you. -- Best Regards, Shengy

Hello Cristina, > In the attach you can find the trace of the registration. I have checked your tracefile and confirm: that is a problem which needs further debugging. Up to now I did not activate "WITH_REGINFO" in my installation, therefore I cannot compare. If I find time (this weekend) I will do that and come back with the findings. BR Franz

rfc: kamailio.cfg polishing for v4.4
by Daniel-Constantin Mierla 20 Feb '16

20 Feb '16

Hello, wondering if people feel it is need to polish the current default kamailio.cfg, to prepare the version for next major release. It can be browsed online at: - https://github.com/kamailio/kamailio/blob/master/etc/kamailio.cfg It is mainly about very common scenarios that are encountered out there and we should deal with by default. Have in mind that there are the basic and advanced versions of kamailio.cfg in the etc folder. Also, I am looking for tunings for core parameters and module parameters that make the config more suitable for common use case. Speaking of those extra config files, I think the kamailio-advanced.cfg and kamailio-basic.cfg should be deployed in shared doc folder, not being active configs upon default installation. Cheers, Daniel -- Daniel-Constantin Mierla http://twitter.com/#!/miconda - http://www.linkedin.com/in/miconda Book: SIP Routing With Kamailio - http://www.asipto.com http://miconda.eu

Registration Failure
by Cristina Caridi 19 Feb '16

19 Feb '16

Hello, I'm a new starter of Kamailio (SER). I am using the version 4.4.0-dev6 in a Debian machine. I've configured all the IMS network elements, the FHoSS and also Boghe IMS/RCS client in a Windows machine. When an IMS user belonging to my network tries to register and IP SEC mechanism is enabled, the registration flow stops at 401 Unauthorized from S-CSCF -> I-CSCF -> P-CSCF -> client. The problem is that the HSS in MAA message does not send the SIP-Auth-Data-item that should be cointain the Confidentiality Key and the Integrity Key; so the client is not able to challenge the S-CSCF sending another REGISTER message. Do you have any suggestions about this? When IP SEC is disabled (by managing client options), the registration works well. Maybe is there any configuration at HSS level that i'm not considering? Thank you in advance for your help, Cristina

dispatcher flag
by alexandre.anconetti＠orange.com 19 Feb '16

19 Feb '16

Hi, I'm using the dispatcher module with Kamailio 4.3.4, the keep alive mechanism and the routing are OK, but I would like to get in my request_route the flag(s) (active, inactive, probing ...) that the dispatcher give to each destination. I know that in command line I can run kamcmd or kamctl to get : NRSETS: 1 RECORDS: { SET: { ID: 1 TARGETS: { DEST: { URI: sip: xxx.xxx.xxx.xxx:xxxx FLAGS: IP PRIORITY: 0 } DEST: { URI: sip:xxx.xxx.xxx.xxx:xxxx FLAGS: AP PRIORITY: 0 How can I get that in the request_route process ? Any suggestion would be appreciated ;) Best Regards, Alexandre. _________________________________________________________________________________________________________________________ Ce message et ses pieces jointes peuvent contenir des informations confidentielles ou privilegiees et ne doivent donc pas etre diffuses, exploites ou copies sans autorisation.

Hi Franz, Thanks for your response. Even we observed in Wireshark traces, no username is included in REGISTER request. Any changes required? No, we are not using NATURAL in our platform. Observed there is no communication between PCSCF – ICSCF while registration and also attaching the tracefile(tcpdump) using command “tcpdump -i any -s 3000 -w /var/tmp/trace_OpenIMS.pcap not port 22 and not port 3306”.

siptrace module plain sip mode
by Grant Bagdasarian 17 Feb '16

17 Feb '16

Hello, The documentation of the siptrace module specifies duplication of sip messages to a capture server using the HEP protocol or plain SIP mode. Which params to I need to set (and with which values) in the siptrace and sipcapture to enable plain SIP mode? I tried several configurations but none of the worked. Seems like only HEP works. My test kamailio (sip capture node with sipcapture module) doesn't receive the duplicated SIP messages. Any ideas? Regards, Grant

db_cluster.so module and kamctlrc DBHOST= field
by Hosted Services 16 Feb '16

16 Feb '16

Hi there, New user to Kamailio here. We currently have it up and running in a virtualized environment with 1 Kamailio sever, 1 Asterisk server and 1 MySQL server. I'm currently writing install scripts to make deploying new nodes/servers easy and to keep settings the same across the board. I've chosed to load the db_cluster.so module in kamailio.cfg, as we will have 2x MySQL servers in master-master replication which will contain the 'kamailio' and 'asterisk' tables. I've just hit a stumbling block - in `kamctlrc`, there is a field called `DBHOST=`. How can I reference my cluster here? In kamailio.cfg, I simply define DBURL as "cluster//<clustername>". What is the syntax for 'DBHOST=' in 'kamctlrc'? Can I reference the cluster? Can I have 2 separate DBHOST= lines? Looking for some guidance on this one. Thanks, Derek B.

I see there is a new SQLops function sql_query_async that has been added in 4.2 (I believe?). Is there a good way to perform database insert using version 4.0? Using mysql Thanks! -dan

Textops and Multipart Body - adding ISUP
by Sergey Basov 16 Feb '16

16 Feb '16

Hi All. I need to use SIP-I with my upstream to set A number as unknown. I was read about adding incapsulation ISUP using if(has_body("application/sdp")) { set_body_multipart(); msg_apply_changes() $var(acm) = "7e Od 04 55 75 69 20 4d 61 6b 65 43 61 6c 6c"; append_body_part("$var(acm)","application/isup;version=itu-t92+","signal; handling=optional"); msg_apply_changes() xlog("L_INFO", "ISUP Changes Applied Succesfully"); } It is converts body to multipart and inserts ISUP But it inserts is as text. Is there any possibility to insert basic ISUP message to update it after using sipt_destination($rU, 31, 4); and sipt_set_calling($fU, 4, 0, 3); Thank you. -- Best regards, Sergey Basov e-mail: sergey.v.basov(a)gmail.com

kamailio 4 with asterisk
by Sébastien Brice 15 Feb '16

15 Feb '16

this one (written by Daniel) http://kb.asipto.com/asterisk:realtime:kamailio-4.0.x-asterisk-11.3.0-astdb maybe a bit outdated but still consistent ? the thing i am really stuck with (and concerning real-time) is that none of my extensions (from asterisk CLI) are online: ns3325046*CLI> sip show peers Name/username Host Dyn Forcerport Comedia ACL Port Status Description Realtime 102/102 (Unspecified) D Auto (No) No 0 Unmonitored Cached RT 103/103 (Unspecified) D Auto (No) No 0 Unmonitored Cached RT 2 sip peers [Monitored: 0 online, 0 offline Unmonitored: 0 online, 2 offline] that drives asterisk crazy ! and logger reports: app_dial.c:2411 dial_exec_full: Unable to create channel of type 'SIP' (cause 20 - Subscriber absent) every time i place a call. The tutorial written by daniel mention a channel configuration pretty minimal: INSERT INTO sipusers (name, defaultuser, host, sippasswd, fromuser, fromdomain, mailbox) VALUES ('102', '102', 'dynamic', '102', '102', 'yoursip.com', '102'); and since there's no context associated to the 102 extension i cant figure out where that channel enter the dialplan ? [public] [LocalSet] [default] ???? and a dialplan exten => _1XX,1,Dial(SIP/${EXTEN}) exten => _1XX,n,Voicemail(${EXTEN},u) exten => _1XX,n,Hangup exten => _1XX,101,Voicemail(${EXTEN},b) exten => _1XX,102,Hangup i am sorry to bother you with issues more asterisk oriented than kamailio. By the way i took a good start with kamailio as it seems to work flawlessly on my system. thx you.

In essence asterisk uses the kamailio database, UA registers on kamailio and is stored there, asterisk sees the same data (realtime). Sébastien BRICE VoIP, Support et Intégration

I tryed to place a call between 102 and 103 extensions and experimenting an issue Asterisk tells me that the subscriber is absent and I'm sent directly to voicemail ! -- Executing [103@public:1] Dial("SIP/102-00000001", "SIP/103") in new stack [Feb 14 21:00:15] WARNING[19444][C-00000001]: app_dial.c:2411 dial_exec_full: Unable to create channel of type 'SIP' (cause 20 - Subscriber absent) ns3325046*CLI> sip show peers Name/username Host Dyn Forcerport Comedia ACL Port Status Description Realtime 102/102 (Unspecified) D Auto (No) No 0 Unmonitored Cached RT 103/103 (Unspecified) D Auto (No) No 0 Unmonitored Cached RT 2 sip peers [Monitored: 0 online, 0 offline Unmonitored: 0 online, 2 offline] apart that my sip.conf and extensions.conf are very minimal: [LocalSets] exten => _1XX,1,Dial(SIP/${EXTEN}) exten => _1XX,n,Voicemail(${EXTEN},u) exten => _1XX,n,Hangup exten => _1XX,102,Voicemail(${EXTEN},b) exten => _1XX,103,Hangup [general] context=LocalSets ; Default context for incoming calls.

uac module configuration
by Andrew Tan 15 Feb '16

15 Feb '16

Hello, Submit a ticket in GitHub apologize about that I should have sent my question here. I would like some help in configuring the uac module to route to an gateway without specifically setting the URI-domain from the UAC. I would like to set change it in the Kamailio side. Currently I use uac_auth on failure route. All is working if I set the URI from on the client to xxx(a)gatewayaddress.com. But if I just dial just the number as is which translate to xxx(a)kamailioserver.com the invite doesnt go anywhere. My failure route is like so failure_route[MANAGE_FAILURE] { xlog("DEBUG: MANAGE FAILURE ROUTE: "); if ($T_reply_code == "407") # there's also 401 { $avp(arealm) = GATEWAY; $avp(auser) = USERNAME; $avp(apass) = PASSWORD; #$ru = "sip:" + $rU + "@" + $sel(cfg_get.pstn.gw_ip) + ":" + $sel(cfg_get.pstn.gw_port); #rewritehost("sip.ca.didlogic.net"); uac_auth(); rtpengine_offer("force trust-address replace-origin replace-session-connection ICE=remove RTP/AVP"); route(NATMANAGE); route(RELAY); exit; } } Thank you

LCR
by Alexey V. Panfilov 15 Feb '16

15 Feb '16

Hello, I'm using LCR module in my kamailio setup. I can access to the gw_uri_avp's value of matched gateway, but I'd like to get value of selected id of lcr_rule_target. Is there any way to get it? Thanks. P.S. Access to value of custom table's field (for example, named as 'flags') of cr_rule_target will be better. I'd like to store at this field the price of selected direction. -- Best regards, Alexey V. Panfilov

Kamailio 4 && Asterisk. Getting started
by Sébastien Brice 14 Feb '16

14 Feb '16

Hi everyone I did follow the tutorial Kamailio 4.0.x and asterisk written by Daniel-C and I need a hand :-) after a successful install (kamailio and asterisk on the same server), i did setup 2 sip extensions (102 and 103) and tryed to place a call between them and experimenting an issue Asterisk tells me that the subscriber is absent and I'm sent directly to voicemail ! -- Executing [103@public:1] Dial("SIP/101-00000001", "SIP/103") in new stack [Feb 14 21:00:15] WARNING[19444][C-00000001]: app_dial.c:2411 dial_exec_full: Unable to create channel of type 'SIP' (cause 20 - Subscriber absent) ns3325046*CLI> sip show peers Name/username Host Dyn Forcerport Comedia ACL Port Status Description Realtime 102/102 (Unspecified) D Auto (No) No 0 Unmonitored Cached RT 103/103 (Unspecified) D Auto (No) No 0 Unmonitored Cached RT 2 sip peers [Monitored: 0 online, 0 offline Unmonitored: 0 online, 2 offline] Actually none of my extensions are online and i am wondering if Kamailio forward register with asterisk ? transport between K and Asterisk seems ok (at least i did setup bindport in both sip.conf and kamailio.cfg) apart that my sip.conf and extensions.conf are very minimal: exten => _1XX,1,Dial(SIP/${EXTEN}) exten => _1XX,n,Voicemail(${EXTEN},u) exten => _1XX,n,Hangup exten => _1XX,102,Voicemail(${EXTEN},b) exten => _1XX,103,Hangup [general] context=LocalSets ; Default context for incoming calls. Defaults to 'default' rtcachefriends=yes ; Cache realtime friends by adding them to the internal list I am a bit new with Kamailio and I don't know if this behavior is normal since i have a sipregs mysql table that could do the job on purpose? Could someone point me to the right direction and enlight my knowing, thanks you thx you
