Suspend INVITE between ip4 and ip6 users
by Péter Barabás 08 Oct '21

08 Oct '21

Hi, I try to modify the kamailio configuration to work between ipv4 and ipv6 clients. Clients are mobile sofphones, so they are mostly in background without registration. 1. When an INVITE arrives from IPV4 address, transaction is suspended and a push notification is sent to callee. 2. Callee gets push notification and registers to kamailio. 3. INVITE transaction continues. My kamailio config is based on this article: https://kb.asipto.com/kamailio:kamailio-mixed-ipv4-ipv6 using rtpengine. If clients are in foreground it works fine. But, when a client is in background, kamailio knows nothing about the callee’s IP address (ipv4 or ipv6). The problematic case is the call from IPV4 to IPV6. In this case the FLB_V4V6 flag is missing at continue, since in IPV4V6 route it cannot be set and the rtpengine tries the IPV4->IPV4 case. From the other side IPV6->IPV6. It is understandable, since FLB_V4V6 flag is missing in this case. My question is: where and when should I set this flag? Thanks. Peter

Missing line in line.count transformation
by Daniel Donoghue 08 Oct '21

08 Oct '21

I think I’ve found an edge case with the string transformations for line.count: In pv_trans.c, the following code does not appear to consider the last line if there are multiple lines and the last one is not terminated with \n. case TR_LINE_COUNT: n=0; for(i=0; i<val->rs.len; i++) if(val->rs.s[i]=='\n') n++; if(n==0 && val->rs.len>0) n = 1; val->flags = PV_TYPE_INT|PV_VAL_INT|PV_VAL_STR; val->ri = n; val->rs.s = int2str(val->ri, &val->rs.len); break; This means that my count is always one off unless I force a blank line at the end of my string. Also, this code does not cater for cases where there is a different line terminator, such as CR or CRLF as is the case when the string comes from a Mac or windows system, respectively; it might be useful to have a transformation for doing that as I’ve had to hack it using s.replace with hexadecimal escape codes (\r and \n do not work) in a variable. With every blessing, — Daniel Donoghue

Parsing Error in Timer Module of kamailio
by Surabhi Garg 07 Oct '21

07 Oct '21

Hi Team, Greetings! I am trying to use Timer Module of Kamailio to keep calling particular route at particular time interval. Here is the snippet of my config: loadmodule "timer.so" modparam("timer", "declare_timer", "MYTIMER=SHUTDOWN,5000,slow,enable"); route[SHUTDOWN] { xlog("system shutdown: $sht(graceful_shutdown=>shutdown)\n"); } But after restarting the Kamailio, I keep on getting parsing errors in every 5 sec and my route "SHUTDOWN" never get called. Which means timer is getting called in every 5 sec but not able to call the route. Could you please help me with this why these parsing errors coming? am I missing some arguments here? Kamailio Version: 5.5.X. Errors: Sep 23 15:29:31 N1VL-PA-SIP01 /usr/local/kamailio-5.5/sbin/kamailio[9907]: ERROR: <core> [core/parser/msg_parser.c:748]: parse_msg(): ERROR: parse_msg: message=<GET /timer HTTP/0.9#012#012> Sep 23 15:29:31 N1VL-PA-SIP01 /usr/local/kamailio-5.5/sbin/kamailio[9907]: ERROR: timer [timer.c:204]: timer_handler(): parse msg failed Sep 23 15:29:36 N1VL-PA-SIP01 /usr/local/kamailio-5.5/sbin/kamailio[9907]: ERROR: <core> [core/parser/msg_parser.c:748]: parse_msg(): ERROR: parse_msg: message=<GET /timer HTTP/0.9#012#012> Sep 23 15:29:36 N1VL-PA-SIP01 /usr/local/kamailio-5.5/sbin/kamailio[9907]: ERROR: timer [timer.c:204]: timer_handler(): parse msg failed Also, in place of timer module I tried using rtimer module as well which is also giving me similar results as per my requirement. But Could you please help me with the pros and cons of both the modules timer and rtimer. Any thoughts on this would be appreciated Surabhi Garg Mobile - 91 783 888 7523

[kamailio/kamailio] SIP Preconditions Settings?
by Luis Joel Borrego Soto 07 Oct '21

07 Oct '21

Hi Team, According with the RFC3312 (https://datatracker.ietf.org/doc/html/rfc3312) The SDP parameters are the following We define the following media level SDP attributes: current-status = "a=curr:" precondition-type SP status-type SP direction-tag desired-status = "a=des:" precondition-type SP strength-tag SP status-type SP direction-tag confirm-status = "a=conf:" precondition-type SP status-type SP direction-tag **precondition-type = "qos" | token strength-tag = ("mandatory" | "optional" | "none" = | "failure" | "unknown")** status-type = ("e2e" | "local" | "remote") direction-tag = ("none" | "send" | "recv" | "sendrecv") Which one should be the equivalent in the Kamailio?, is the a specific module? Br, Joel Borrego (joel.borrego)

Need kamailio to use advertise public IP only in cases of SIP communication over internet.
by Voip support 06 Oct '21

06 Oct '21

Dear Community, I have a need of communicating with other servers using private IP with private IP in Via and SDP connection information but at same time sometime need connect to public IP SIP server and on outgoing INVITE's i need advertise public IP in Record-Route and SDP Connection information. Currently if i work on listen=udp:privateip:5060 i get working the LAN part but cannot work over internet (no audio) but when i add advertise i get SDP public IP also over local network. Is it possible to solve this case using one NIC adapter? I am using RTPProxy. Please help me out. I tried to add second network adapter with advertise and mhomed=1 something started to work but i think i would need work on the call direction and different rtpproxy_manage handling on outside INVITEs and incoming 200 OK responses. I am not sure if this is the right way to do it - maybe there is some easier method of achieving what i need using one interface ? Best regards, Tom

Understanding regex format for subst_hf
by Joel Serrano 06 Oct '21

06 Oct '21

Hey guys, I'm trying to do a replacement regex using subst_hf but I can't seem to get the format right and the docs are confusing. *subst_hf: *docs say it uses perl-like regex (as I understand it, that would mean PCRE). Docs also say in the 'subexp' param that it uses the same format as *subst.* *subst: *at the beginning it says it uses perl or sed format, but in the '/re/repl/flags' param it says that sed format. https://www.kamailio.org/docs/modules/devel/modules/textops.html#textops.f.… 4.20. subst_hf(hf, subexp, flags) Perl-like substitutions in the body of a header field. Meaning of the parameters is as follows: - *hf* - header field name. - *subexp* - substitution expression in the same format as of the 'subst' function parameter. - *flags* - control flags - it has to be one of: a - all headers matching the name; f - only first header matching the name; l - only the last header matching the name. 4.16. subst('/re/repl/flags') Replaces re with repl (sed or perl like). Meaning of the parameters is as follows: - *'/re/repl/flags'* - sed like regular expression. flags can be a combination of i (case insensitive), g (global) or s (match newline don't treat it as end of line). 're' - is regular expression 'repl' - is replacement string - may contain pseudo-variables 'flags' - substitution flags (i - ignore case, g - global) I'm trying to use this: subst_hf("X-myheader", "/^(?!string1 |example2-|text3 )(.*)/myprefix \1/", "a") In an online tester using PCRE, the format is correct, but Kamailio doesn't like it: Oct 4 09:29:16 cops-n1 cops[15957]: ERROR: <core> [core/re.c:285]: subst_parser(): bad regular expression ^(?!string1 |example2-|text3 )(.*) in /^(?!string1 |example2-|text3 )(.*)/myprefix \1/ If I remove the negative lookahead chars (?!) then kamailio doesn't complain but the regex doesn't do what I want. Does this mean that Kamailio won't support negative lookahead for subst regex replacements? What I'm trying to achieve is something along: "If the value of the header Myheader doesn't start with ABC, DEF or HIJ, then prefix it with XYZ" Any suggestions/ideas on how to achieve this? Thanks, Joel.

seas module
by Daniel Paape 05 Oct '21

I am having some difficulties with the seas module under Kam 5.5.2. If my application server is not connected then the config file script below never returns if (!as_relay_t ("myserver")) { Xlog ("LM_NOTICE", "myserver not connected\n"); } A diagnostic in the "seas.c" file does report that the app server is not connected, but the one above is never printed.

Kamailio/RTPengine as a proxy for FreePBX/Asterisk...
by Micah Quinn 03 Oct '21

03 Oct '21

Hello all, I'm new to Kamailio, so bear with me as I stumble through this. First, I'll describe what I'm trying to achieve at a high level and then perhaps somebody can advise me on whether Kamailio is a good fit for this solution or not. I'd like to be able to deploy a small appliance type server to our customer's sites that just runs Kamailio and a VPN connection back to our datacenter. At our datacenter, we run virtualized instances of Asterisk for each of our customers. The idea is that Kamailio would act as a transparent proxy through to the Asterisk instance under nominal conditions and as a basic SIP router in the case that the Asterisk instance is unavailable. This degraded functionality would then at least allow extension to extension calling even if the Internet or Asterisk instance is down. I'm currently using dispatcher with a single entry in preparation for a time when we might want to failover to another Asterisk instance. I'm forwarding all REGISTER and INVITE messages to the server chosen from ds_select_dst. Initially this all seems to work as I can register with a softphone and pjsip show endpoints shows my softphone connected. However, when I attempt to call any extension (my own or another) Asterisk responds to the INVITE message with a "401 Unauthorized" message and the typical "The person at extension XXXX is unavailable...". I know that more details might be necessary to troubleshoot this, but I didn't want to include everything in one post and risk cluttering it up with unnecessary information. If anyone can confirm that this is a reasonable way to approach the problem, I can then provide whatever relevant data is necessary to get deeper into it. (I've used sngrep, logging, asterisk cli, etc.) Thanks in advance for any help.

Kamailio 4.4 + rtpproxy behind the NAT (debian stretch 9.13)

Dear, I am testing the kakamilio 4.4 with rtpproxy on Debian stretch 9.13 I have installed the packages - apt-get install kamailio and rtpproxy. - kamailio 4.4 - rtpproxy Basic version: 20040107 *My version of RTPPROXY doesn't have the -A parameter so that means without advertising there is no way to work behind NAT?
