Kamailio Asterisk integration with docker DNS Problem
by Amir 15 Jul '19

15 Jul '19

Hi I have created a kamailio container with docker and two asterisk container And this is my dispatcher list: *1 sip:asterisk:50601 sip:asterisk2:5060* and this is my both asterisk SIP.conf *[Kamailio]host=kamailioport=5060insecure=invitetype=friendcontext=from-internal* The problem is that I use User-defined networks which has its own DNS when a container starts a dns record would be set If I start a kamailio first then start two asterisks the asterisk works fine because the name "kamailio" has been set in docker dns but I should restart the kamailio because at startup It could not resolve astersik dns records after the everything works fine but if the any of the asterisk instances crash/stop kamailio can not detect that because a dns record would not be available: *17(22) ERROR: <core> [core/resolve.c:1684]: sip_hostport2su(): could not resolve hostname: "asterisk2"17(22) ERROR: tm [ut.h:309]: uri2dst2(): failed to resolve "asterisk2"17(22) ERROR: tm [uac.c:452]: t_uac_prepare(): no socket found17(22) ERROR: dispatcher [dispatch.c:3110]: ds_ping_set(): unable to ping [sip:asterisk2:5060]* It is kind of loop , I think maybe I can fix asterisk problem with asterisk realtime and set the sip.conf in database. anyone has any suggestion for this problem?

Wrong $rm value
by Alexandru Covalschi 14 Jul '19

14 Jul '19

Hello list, I use kamailio 5.2.3 from repo's on stretch in docker. I use python KEMI + async and encountered weird behaviour: after t_continue $rm shows OPTIONS instead of REGISTER/INVITE. I wonder if that's correct behaviour, because for me it looks like a bug. Repeating is easy - just check $rm after t_continue. ________________________________ Regards, Alexandru Covalschi VoIP Engineer and System Administrator tel: +37367367850

Check if an INVITE comes from uac_reg endpoint
by Diogo Hartmann 14 Jul '19

14 Jul '19

Hello Kamailio experts, We were already able to register correctly at a SIP Provider using uacreg table. Now, we would like to validate inbound calls coming from this registered provider, sending them to a specific dispatcher group. I tried reading the uac module docs, found *uac_reg_lookup* function, but i'm not sure if that's we need. Could someone please help me to understand if UAC has a function to do that, or if we need to make some? Thanks!!

14 Jul '19

hello, I use Kamailio as my Icscf in IMS network . after receiving Invite Request from SCSCF to ICSCF‌, a LIR request sent from ICSCF to FHoss. User_Unknown response received in all states. I checked every thing carefully , users are registered and defined in HSS and every configuration done . What's wrong? is it possible that icscf has problem? or it can be FHoss bug?

Long distance rtpengine communication
by Koray Vatansever 12 Jul '19

12 Jul '19

Hi all, We have kamailio servers which communicate with the geographically distributed rtpengine servers. Sometimes udp packets are lost or delayed between kamailio and rtpengine. And this causes call drops... Since rtpengine communication is synchronized and tcp worker processes are blocked, I couldn't set higher timeout values and more retry count. Are there any suggestions to overcome this problem? Thanks, Koray

Variables for P-Called-Party-ID Header
by Benjamin Tietz 12 Jul '19

Hi, I have some INVITES where the called number is in the P-Called-Party-ID header: P-Called-Party-ID: <sip:+123456789@sip-trunk.example.com;user=phone> Is there any function or variable where the user is stored or made available? In this case +123456789 Thanks, Benjamin

SIP URI Evaluation and Forwarding
by Ronald Hartmann 12 Jul '19

12 Jul '19

Good Day List, I am very new to Kamailio and trying to understand at 10,000 feet how it may be able to be used. I was wondering if the following Scenario would be possible and if so what modules would accomplish this aspect. (Any URLs for further reading would be appreciated) Scenario: Given 1) SoftPhones will register as follows sip uri, user(a)subdomain.myvoipserver.com 2) The following users are authorized to connect (this would be stored in a config file etc): 1001,1003,1007 are valid users for apples.myvoipserver.com 1001,2213,5817 are valid users for oranges.myvoipserver.com Is it possible for Kamailio to perform the following evaluation and then take the appropriate steps: If [domain is apples.myvoipserver.com AND user portion is 1001] then Forward/Proxy the SIP/RTP packets to Asterisk server responsible for registration and audio for the domain apples.myvoipserver.com Else if [domain is oranges.myvoipserver.com AND user portion is 2213] then Forward/Proxy the SIP/RTP packets to Asterisk server responsible for registration and audio for the domain oranges.myvoipserver.com Else Silently Drop packets etc. given the above evaluation rules, a user who tries to register as 1001(a)apples.myvoipserver.com would be granted access and their SIP Packets and subsequent RTP would be forwarded to the asterisk server at apples.myvoipserver.com, where said server would take care of the Registration, and any subsequent calls, subscriptions, Options etc. 1004@ apples.myvoipserver.com Would not match the authorized list for apples.myvoipserver.com (1001,1003,1007), therefore this registration attempt would be silently dropped 2213(a)apples.myvoipserver.com would be granted access and their SIP Packets and subsequent RTP would be forwarded to the asterisk server at oranges.myvoipserver.com, where said server would take care of the Registration, and any subsequent calls, subscriptions, Options etc. Thanks for any information to assist me in understanding how this would work. ~ron

Re: [SR-Users] kamailio warning
by Henning Westerholt 10 Jul '19

Hello Ali, (please keep the sr-users list in CC, that other people can also participate) Remove the “-D” from your Kamailio command line – then the warning will disappear. This is also necessary because you want to have Kamailio listen on several addresses. If you want to test it more in a production like setting, you should also remove the “-E” from the command line. You will find the logging in your system log then.

Hello, Could someone help me to set a variable as a string in Kamailio? At the moment i'm using the following statement: *$var(account)=$(au{s.substr,0,8}); * *xlogl("L_INFO", "[1234] Account: $var(* *account* *)\n");* which is working fine, but i need to change it into: *$var(account)=$(au{s.select,0,-}{s.toupper})-$(au{s.select,1,-});* By doing this I'm getting the error: *[core/rvalue.c:1007]: rval_get_int(): automatic string to int conversion for "AT" failed[core/rvalue.c:1912]: rval_expr_eval_int(): rval expression conversion to int failed (729,30-729,59)* I tried also: *$var(account)="" + "$(au{s.select,0,-}{s.toupper})-$(au{s.select,1,-})";* But, then I'm getting: *Account = $(au{s.select,0,-}{s.toupper})-$(au{s.select,1,-})* instead of the value. What is the correct way to set it? Thank you.

How to statelessly send a reply to custom destination?
by George Diamantopoulos 05 Jul '19

05 Jul '19

Hello all, I've been trying to handle OPTIONS statelessly, but proper handling fails for UACs behind NAT without ALG. I thought I'd overcome this by setting the $du pseudovariable, but apparently I'm missing something. The following does not work: if ($Rp == "6050") { force_send_socket(udp:10.10.10.10:6050); } $du = "sip:" + $si + ":" + $sp; sl_send_reply("200","OK"); exit; I'm now realising that I put this in request_route() so force_send_socket() and $du have no use whatsoever, since the request is not forwarded anywhere. Is this the reason? So the question is, how can I do the following things for a stateless reply: a) choose a sending socket for the reply and b) change the destination for the reply to something other than the URI in the first Via header. Thanks! BR, George

Append a new branch while the other one is in ringing state

Hi all, I want to fork a new branch, while the first one is ringing. Forking will take place in a rtimer process. So I will save the invite transaction in a htable, and using this transaction info I need to append a branch. I saw TSILO module provides some methods to append branch. However documentation says that it can be used when register message received. What is the best way to implement this? Thanks, Koray

people complain Kamailio not handling stale nonce correctly
by Juha Heinanen 03 Jul '19

03 Jul '19

Several people are complaining on baresip git that Kamailio is among those SIP servers that don't handle stale nonce properly, i.e., don't include stale=true flag in WWW-Authenticate header of 401 response. I have tried to tell that Kamailio does what it has been configured to do, but the response is that "by default" Kamailio works incorrectly. "By default" I guess refers to the example Kamailio kamailio.cfg in etc dir. How about adding stale nonce handling to the example config, for example, like in below? -- Juha *** kamailio.cfg 2019-06-13 17:17:17.182148989 +0300 --- /tmp/kamailio.cfg 2019-07-02 18:02:02.947183503 +0300 *************** *** 745,753 **** if (is_method("REGISTER") || from_uri==myself) { # authenticate requests ! if (!auth_check("$fd", "subscriber", "1")) { ! auth_challenge("$fd", "0"); ! exit; } # user authenticated - remove auth header if(!is_method("REGISTER|PUBLISH")) --- 745,759 ---- if (is_method("REGISTER") || from_uri==myself) { # authenticate requests ! switch (auth_check("$fd", "subscriber", "1")) { ! case 1: ! break; ! case -4: ! auth_challenge("$fd", 17); ! exit; ! default: ! auth_challenge("$fd", "0"); ! exit; } # user authenticated - remove auth header if(!is_method("REGISTER|PUBLISH"))

DMQ: dmq_t_replicate()
by Lars Olsson 02 Jul '19

02 Jul '19

Hi, I am trying to replicate a REGISTER request between several nodes. When I am using dmq_t_replicate(), it ends the execution of the script. It this correct or I have missed anything? I can not find anything in the documentation of the DMQ module the says that it will end the script execution. Is it recommended to use the DMQ module or should I simply forward the request instead as described in https://medium.com/@tumalevich/kamailio-registration-replication-without-dm… Best Regards, Lars

[DMQ] Sync DLG_STATE_CONFIRMED_NA dialog state ?
by Mathieu Bodjikian 02 Jul '19

02 Jul '19

Hello, We are using DMQ module to sync dialogs between 3 Kamailio boxes. We are using last Kamailio version (5.2.3). >From our understanding, the state DLG_STATE_CONFIRMED_NA is not synced over DMQ (https://github.com/kamailio/kamailio/blob/a84a3ea618f0e602a8892c37fce7f4e72…) With containerized environement, the ACK's can go to any Kamailio instance, which lead to : On first box : -> INVITE received -> Dialog created + KDMQ sent (state DLG_STATE_UNCONFIRMED) -> 180 | 183 received -> Dialog updated + KDMQ sent (state DLG_STATE_EARLY) -> 200 received -> Dialog updated + KDMQ NOT sent (DLG_STATE_CONFIRMED_NA) On second box : -> ACK received : - next_state_dlg(): bogus event 6 in state 2 for dlg - dialog not updated - KDMQ with state DLG_STATE_CONFIRMED not sent On first box, after timeout : -> After timeout : - dialg with incorrect timeouts (since box2 didn't send dialog update) - tm sends BYE in both ways - bye_reply_cb(): inconsitent dlg timer data on dlg We see two solutions : - We add DLG_STATE_CONFIRMED_NA to states we sync on dlg_dmq_replicate_action - We manage to route the ACK on the same instance that received first INVITE (could be tricky) Which one is preferable ? Kind regards, Mathieu Bodjikian

question about reply route
by Iván Aponte 02 Jul '19

02 Jul '19

Hello, I have a question about record route and via headers. My scenario is the following: [asterisk] ---- [kam] -------- [trunk] 10.142.0.27 10.142.0.6 200.x.x.x I have an asterisk an a kamailio in a private ip network (10.142.0.0/24). Kamailio has the address 10.142.0.6 but is also natted 1:1 to a public ip (35.0.0.6). My problem is that when the invite are replied the asterisk replies to the external ip (35.0.0.6) instead of the internal ip (even though the kamailio replies goes through the internal network) . I tried adding a reply route to change the advertised address to no avail. any advice would be appreciated. this is my conf: LISTEN="listen=udp:0.0.0.0:5060 advertise 35.0.0.6:5060" disable_tcp=yes loadmodule "jsonrpcs.so" loadmodule "kex.so" loadmodule "corex.so" loadmodule "tm.so" loadmodule "tmx.so" loadmodule "sl.so" loadmodule "rr.so" loadmodule "pv.so" loadmodule "maxfwd.so" loadmodule "usrloc.so" loadmodule "textops.so" loadmodule "siputils.so" loadmodule "xlog.so" loadmodule "sanity.so" loadmodule "ctl.so" loadmodule "cfg_rpc.so" loadmodule "acc.so" loadmodule "counters.so" loadmodule "permissions.so" loadmodule "ipops.so" modparam("jsonrpcs", "pretty_format", 1) modparam("tm", "failure_reply_mode", 3) modparam("tm", "fr_timer", 30000) modparam("tm", "fr_inv_timer", 120000) modparam("rr", "enable_full_lr", 0) modparam("rr", "append_fromtag", 0) reply_route { xinfo("source $si"); if(!is_in_subnet($si, "10.0.0.0/8")) { set_advertised_address("10.142.0.6"); } else { xinfo("not in subnet"); } } request_route { # per request initial checks route(REQINIT); # CANCEL processing if (is_method("CANCEL")) { if (t_check_trans()) { route(RELAY); } exit; } # handle retransmissions if (!is_method("ACK")) { if(t_precheck_trans()) { t_check_trans(); exit; } t_check_trans(); } # handle requests within SIP dialogs route(WITHINDLG); ### only initial requests (no To tag) # authentication #route(AUTH); # record routing for dialog forming requests (in case they are routed) # - remove preloaded route headers remove_hf("Route"); if (is_method("INVITE|SUBSCRIBE")) { record_route(); } # dispatch requests to foreign domains route(SIPOUT); if ($rU==$null) { # request with no Username in RURI sl_send_reply("484","Address Incomplete"); exit; } } # Wrapper for relaying requests route[RELAY] { if (!t_relay()) { sl_reply_error(); } exit; } # Per SIP request initial checks route[REQINIT] { if($ua =~ "friendly-scanner|sipcli|VaxSIPUserAgent") { # silent drop for scanners - uncomment next line if want to reply # sl_send_reply("200", "OK"); exit; } if (!mf_process_maxfwd_header("10")) { sl_send_reply("483","Too Many Hops"); exit; } if(is_method("OPTIONS") && uri==myself && $rU==$null) { sl_send_reply("200","Keepalive"); exit; } if(!sanity_check("1511", "7")) { xlog("Malformed SIP message from $si:$sp\n"); exit; } } # Handle requests within SIP dialogs route[WITHINDLG] { if (!has_totag()) return; # sequential request withing a dialog should # take the path determined by record-routing if (loose_route()) { if ( is_method("NOTIFY") ) { record_route(); } route(RELAY); exit; } if (is_method("SUBSCRIBE") && uri == myself) { send_reply("405", "Method Not Allowed"); exit; } 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 route(RELAY); exit; } else { # ACK without matching transaction ... ignore and discard exit; } } sl_send_reply("404","Not here"); exit; } route[SIPOUT] { if (uri==myself) return; append_hf("P-hint: outbound\r\n"); route(RELAY); exit; } -- Iván Aponte Office: +58(212)9923193 Mobile: +58(412)2774713
