Hello all, I'm using sqlops module to connect to postgres and get the routing of calls from postgresql database. In order to troubleshoot issues in case they happened, I added each call details to Kamailio log. In some cases, when there is heavy traffic load (around 100 cps), I don't find some calls in Kamailio log, knowing that I can find them on the switch log (switch sending the invite packets to Kamailio). When checking the traces on these calls taken by the switch, it's clear that Kamailio is not responding to the invite packets sent by the switch. It could be because there are no available process to handle the call at this moment (I have set fork=14) Is it possible to check if there are calls pending in the queue? Regards,

proper way for infinite loop in event_route for evrexec module

by Patrick Karton

Hello i would like to use the evrexec module to execute background jobs over exec module mainly because i want to be able to trigger that route manually via rpc from time to time. in the documentation its is stated we should use tasks that run forever and except using while loop i dont see another way. and i dont to want to disable max_while_loops. but if i disable it i will get error message like runaway while (1091, 9): more then 100 loops. so is there another way to do it properly ? Thanks.

Remove and Re add FROM in 200 OK sl reply

by Lewis Hutchinson

Hello All kamailio 5.5.3 KEMI Python Lab environemnt Is there a reason why this does not work? Lines 2 and 3 work but the removal of the initial From is not working on Line 1 1. KSR.hdr.remove("From") 2. KSR.hdr.append_to_reply("From: " +KSR.pv.gete("$fn") + " <"+KSR.pv.gete("$fu") + ">" + ";tag=" +KSR.pv.gete("$ft") + "--1234" + "\r\n") 3. KSR.sl.sl_send_reply(200, "OK") In a SUBSCRIBE/NOTIFY scenario I am trying to control the From Tag returned in the 200OK so I can use the same one in subsequent NOTIFY messages generated outside of Kamailio, my theory is use the From tag in the Subscribe and append it on the reply with -1234 for example (this is only in a Lab at this stage, any other options please let me know) Whenever I do this I end up with 2 From headers (see below) SIP/2.0 200 OK Via: SIP/2.0/UDP 192.168.1.67:5060;branch=z9hG4bK-f710a11a;rport=46404;received=xx.yy.xx.yy From: " testuser" sip:limeant30@sip.viazeta.com;tag=bf8745def06c7b12 To: <sip: testuser(a)sip.viazeta.com>;tag=47969b75f14e6954812863912d1cf21c.b5f3318f Call-ID: b21ba770-9b5836aa(a)192.168.1.67 CSeq: 18137 SUBSCRIBE Contact: "testuser" <sip:testuser@ xx.yy.xx.yy:46404> Expires: 3600 From: "testuser" sip:testuser@testbed.com;tag=bf8745def06c7b12--1234 Content-Length: 0 I have tried many many variations but the original From header always persists I have checked the debug logs and it says it has been removed Anyone know what I am missing? And how to get KSR.hdr.remove("From") to work. Looking in a debug log the header is removed. Lewis

Kamailio Configuration Help

by P. White

Hi All, Really sorry to bother everyone, but if possible, can I ask for a little help? I've been attempting to get Kamailio configured and working for some considerable time now (read: Years of occasional tinkering, and weeks of recent dedicated evening work) -- all without success. I have a sip trunk from sipgate, with two PSTN numbers assigned. My local network has a static external IP, with an internal private network. Currently I have Kamailio running within the intenal network along with two physical sip telephones (gigaset and an old grandstream), although I do have the option to put kamailio within a DMZ if necessary. Would anyone have a working config file that they could share please, permitting incoming and outgoing calls? With grateful thanks, Phil

by Bernd Krueger-Knauber

Hi, I tried to remove a Via header line with: remove_hf("Via"); Original I have this 2 lines: Via: SIP/2.0/TCP xxx.xxx.xxx.xxx;branch=z9hG4bK370b.21720bb33c4f8264fde4e7994d288a57.0;i Via: SIP/2.0/TCP yyy.yyy.yyy.yyy:53967;received=yyy.yyy.yyy.yyy;rport=53967;branch=z9hG4bKPjxb0bdb2c9624076815f12937cc9e51d;alias If I insert remove_hf("Via"); in the cfg, I get: Via: SIP/2.0/TCP xxx.xxx.xxx.xxx;branch=z9hG4bK370b.21720bb33c4f8264fde4e7994d288a57.0;i ;received=yyy.yyy.yyy.yyy;rport=53967;branch=z9hG4bKPjxb0bdb2c9624076815f12937cc9e51d;alias Doesn't mattter if the command make sense or not, the result, in my opinion, is wrong.
