2 Asterisk servers re-inviting around kamailio even with t_relay being used?

by JR Richardson

Hi All, I'm using kamailio with carrierroute to load balance calls to other servers. I have 2 testing scenarios set up: sipp><kamailio><asterisk server In the above scenario all SIP transactions, dialogs go through kamailio, INVITE, Trying, ACK, OK, BYE, OK Here is another one: phone><asterisk><kamailio><asterisk server In this scenario only the initial INVITE, ACK and OK go through kamailio, then the 2 asterisk servers finish the session directly to each other with ACK, BYE and OK In both asterisk servers, canreinvite=no is set in peers and general section in sip.conf. The kamailio cfg is using t_relay. No errors are coming up anywhere. Here is a pastebin of the 2 asterisk traces and the kamailio config. http://pastebin.com/Uk9qVhX2 Any ideas on why the call is not maintaining SIP session through the proxy? Thanks.

Strange behavior when rewriting "To" header from failure_route (kamailio - 3.0.2)

piece of code: ........ failure_route[2] { if (!t_is_canceled()) { revert_uri(); sql_query("main", "select username from subscriber where alias='$tU' and alias_seq='2'", "alias_name"); sql_query("main", "select domain from subscriber where alias='$tU' and alias_seq='2'", "alias_domain"); subst_uri('/^sip:.*@.*$/sip:$dbr(alias_name=>[0,0])@$dbr(alias_domain=>[0,0])/'); subst('/^To:.*<sip:.*>/To: <sip:$dbr(alias_name=>[0,0])@$dbr(alias_domain=>[0,0])>\r/'); #<-----THIS ONE DOESN'T WORK PROPERLY sql_result_free("alias_name"); sql_result_free("alias_domain"); setflag(10); if (!lookup("location")) { switch ($retcode) { case -1: case -3: t_reply("404", "Not Found"); exit; case -2: exit; } } append_branch(); route(5); } } route[5] { if (!t_relay()) { sl_reply_error(); } exit; } And with ngrep i can see: # U 10.10.10.10.:5060 -> 10.10.10.15:53286 INVITE sip:ncm0000a@10.20.5.72:5060 SIP/2.0.

Ending a dialog via MI

by Iñaki Baz Castillo

Hi, I'm building an external application in order to end dialogs via XMLRPC MI (Kamailio 1.5.4). For each call of a client I set a dialog profile: dlg_manage(); set_dlg_profile("out","$avp(AVP_CLIENT_USERNAME)"); The problem is that there is no way to find the current dialog information based on dialog profiles, as such information is not provided when running MI dlg_list or dlg_list_ctx. So, is there something I can do? I've realized that dlg_list_ctx also displays the dialog "context": "associated context from modules sitting on top of the dialog module" But of course such field is empty as I don't use a module on top of dialog module. But perhaps I could code something in the dialog module so such value could be set in the script (I need it to display $avp(AVP_CLIENT_USERNAME)). In this way, I would get the dialog list and filter these with "context = SOME_CLIENT_USERNAME". Then I get the h_entry and h_id and can perform the dlg_end_dlg MI command. Any suggestion about it please? BTW: Running dlg_list_ctx via MI FIFO I get this for each dialog: dialog:: hash=3960:1144646733 Should I assume that h_entry is 3960 and h_id is 1144646733? Thanks a lot. -- Iñaki Baz Castillo <ibc(a)aliax.net>

mysql queries per sec forever rising...almost

by Anders

Hi, I use Munin to try to understand what's going on on the server that runs Kamailio (with Siremis). One thing that puzzles me is that if I look at the MySql queries per second, it just keeps going up. The number rises during the time with calls - the more calls the more it rises - and then when there are no calls, it stays at the same level. And this is what I don't understand - when Kamailio is doing nothing, why are there 5k queries per second? Sometimes - every few weeks - it takes a steep drop to very few queries per second... - and then back to rising again. Is this a database issue, a Siremis issue, or a Munin issue? Or is it just something I don't understand that it's supposed to keep rising forever? Thanks! //Anders

Re: [SR-Users] [sr-dev] pua_dialoginfo deletes AVPs?

Hi Jasmin, ah, sorry. Its not available or necessary anymore in 3.0. In 1.5 it also affected the branch_route, i think, but for the newer version this behaviour is now the default. Then in your case its probably another problem.. Cheers, Henning
