crash on using the $expires variable
by Jayesh Nambiar 28 Nov '15

28 Nov '15

Hi, I am trying to extract out the expires value from the incoming REGISTER request. It might be present in the Contact header or as a separate Expires header and hence I planned to use the $expires(max) PV to get this. But kamailio just crashes as soon as I use the variable. Here's when it crashes: if(is_method("REGISTER")) { xlog("L_INFO", "Expires is $expires(max)"); if(!save("location", "0x01")) { t_reply("500", "Error while saving AOR"); } } It crashes at the xlog point. … [View More]Here's the backtrace for reference: Reading symbols from /usr/local/kamailio/sbin/kamailio...done.

restore_uri_reply() called twice in 200OK to BYE

Hi Folks, I have a problem with To and From headers in 200 OK to BYE request. Their URI is doubled when leaving Kamailio.

I think the problem is in registering a function restore_uris_reply() in callbacks in functions (both in replace.c of uac module) * void rr_checker(struct sip_msg *msg, str *r_param, void *cb_param) * static void replace_callback(struct dlg_cell *dlg, int type, struct dlg_cb_params *_params) Both of these callbacks are registered for BYE and ACK requests (INVITE request is using different callback), therefore running restore_uri_reply() twice. For testing purposes after I have removed the callback in rr_checker and recompile the uac module, To and From headers were OK. In my configuration I'm calling uac_replace_to in RELAY route: route[RELAY] { if ( !has_totag() ) { dlg_manage(); uac_replace_to("$ru"); } if (!t_relay()) { sl_reply_error(); } } So I think there is a bug in uac module, when one function is registered twice in callbacks for NON-INVITE requests. Or is there a problem with my configuration script? Can anyone point me to the direction how to solve this issue?

how to log sql query
by John Smolka 27 Nov '15

27 Nov '15

Hi guys, I use kamailio with mysql. Some queries are huge and when I need to debug something it takes a time, so the debbuging would be easier. Is there any way how could I log all sql queries into a log file ? Thanks, John

Media address family
by Sergey Okhapkin 27 Nov '15

27 Nov '15

What is the best way to find out address family (IPV4 or IPV6) of media in SDP? My goal is to reject INVITEs which have different address families in headers and SDP, i.e. IPv4 INVITE with IPv6 media address in SDP and vice versa.

2 Kamailio servers on same domain
by Michael Nielsen 26 Nov '15

26 Nov '15

I've installed Kamailio on 2 different servers. They share the same PostgreSQL database for users etc. I've setup a single domain, sip.my-domain.com, with latency responds to the 2 servers. So a user will always land on the server with the fastest responds in a respective area of the world. However, it seems as if 2 users are registered on different Kamailio servers - even though they share the same database - they cannot call each other? Have I misunderstood something? I've enabled WITH_NAT.

kamailio very slow or stuck during period from time to time
by Thibault Gueslin 26 Nov '15

26 Nov '15

I am facing an issue with kamailio 4.3.3 that is very similar to http://lists.sip-router.org/pipermail/sr-users/2015-May/088195.html Had someone found the solution or faced similar issue ? Sometimes kamailio is receiving the message (check with wireshark, logs in tcp) but the message is not handled nor relayed. After a certain amount of time everything works fine. I will do what as has been advised : enabling pike & check with gdb when it appears. thibault
