if condition causes the kamailio 4.4.1 to not start
by David Escartín Almudévar 04 May '17

04 May '17

hello all we have seen today something quite weird having this line in the kamailio.cfg (1) else if (status =~ "4" || status =~ "5" || status =~ "6") { causes the process not to start hacing this error May 3 10:28:14 xxxx /usr/local/kamailio/sbin/kamailio[2896]: ERROR: <core> [io_wait.h:459]: io_watch_add(): epoll_ctl failed: Invalid argument [22] May 3 10:28:14 xxxx /usr/local/kamailio/sbin/kamailio[2896]: CRITICAL: <core> [tcp_main.c:4432]: tcp_main_loop(): failed to add process 37 unix socket to the fd list May 3 10:28:14 xxxx /usr/local/kamailio/sbin/kamailio[2896]: CRITICAL: <core> [tcp_main.c:4523]: tcp_main_loop(): exiting... but placing (2) } else if (status =~ "^[456]") { instead, makes it work this happens with kamailio 4.4.1 and the platform is running on centos6.5 on the other hand we have the same line (1) on an ubuntu 10.0.4 makes the kamailio also start properly could you know why this is happening? best regards david

How does dlg_bridge work?
by Pranathi Venkatayogi 04 May '17

I have a TEXT call from cust1@somedomain to Kamailio. I have an agent who is logged in, but is not in any call yet. I want now refer cust1@somedomain to talk to agent directly. How do I do that? I tried - dlg_bridge("$dlg(from_contact)", "$var(agentSipAddress)",""); I get an "audio call" from "Kamailio" to customer, but nothing happens on the agent side. I tried "dlg_refer" as well but nothing happens at all. Should I handcraft "Refer" message using uac module and send to "customer" instead? Please suggest.

Kamailio KEMI / Python and the usage of KSR.pv.get("$rm") vs msg.Method
by Samuel F. 04 May '17

04 May '17

Hi, I see in the examples that KSR.pv.get("$rm") is frequently used rather than the more simple msg.Method. Why is this preferred? Kind regards, Samuel F

acces $dlg_var in failure_route
by Diego Nadares 03 May '17

Hi guys, I'm trying to access dialog vars in failure_route with no success. Dialog exists but vars are null and I'can modify them either. Is there any restriction? if ($dlg_var(v1) == 0){ $dlg_var(v1) = "1"; if (is_known_dlg()){ xlog("L_NOTICE", "negative_reply $ci $T_rpl($si) $dlg_var(v2)"); $dlg_var(v2) = $T_rpl($si); } } Log Apr 26 12:36:26 drwsip02 /usr/local/sbin/kamailio[27223]: NOTICE: <script>: negative_reply 6daf5e8d-f47972c1(a)172.31.4.21 * <null>*
