RTPEngine Intermittent One Way Audio Issue SRTP => RTP
by Tim Chubb 07 Feb '15

07 Feb '15

Hi, I am currently experiencing an intermittent one way audio issue, when using RTPEngine and proxying between srtp and rtp. There is no apparent pattern, I have managed to repeat the on the 7th, 23rd, and 63rd calls to a test number, where upon connection only audio in the RTP => SRTP direction was working. All other test calls worked as normal. Digging through the RTPEngine log file the only abnormalities I can see are: Discarded invalid SRTP packet: authentication failed entries on the calls that had the one way audio issue. What could be causing this? Thanks Tim.

Multiple OR into a if
by Igor Potjevlesch 06 Feb '15

06 Feb '15

Hello, I'm very disappointed because of the following behaviour: if ($tu=~"^sip:0[1-9]{9}") { [.] In that case, Kamailio returns TRUE because the instructions in the block are executed. } if ($rU=~"^33" || $rU=~"^0033" || $rU=~"^0[1-9]{9}" || $rU=~"^\+33" || $tu=~"^sip:33" || $tu=~"^sip:0033" || $tu=~"^sip:0[1-9]{9}" || $tu=~"^sip:\+33" ) { [.] In that case, Kamailio should return FALSE because the instructions in the block are not executed. } Am I missed something regarding 'OR' ? Regards, Igor.

Kamailio load balansing 2 servers issues
by Yuriy Gorlichenko 06 Feb '15

06 Feb '15

Hello. We use 2 kamailio server 4.3 master brancher for load balansing cluster. We have some problems with this deplooiment fist of all we have REgstering issue: Witth one server all works fine (we have some endpoints with same creditians) all endpoints reinging well. But at 2 servers we hawe problem with this- call ringing only at one endpoint. We use Database for USRLOC module modparam("usrloc", "db_url", DBURL) modparam("usrloc", "db_mode", 3) modparam("usrloc", "use_domain", MULTIDOMAIN) As i think it mean al connections to servers ives at database. We have one database for 2 servers and this is means it only one table LOCATION for its. The second problen id that when loadbalanser sends bye to kamailio from the outside- bye is not recieves to endpoint. It say that no transaction with this CallID. I think it is because transaction goues through another kamailio and kamiaio that recieves BYE does not know about it transaction. So my first qestion- Does anybody have some information about loafd balansiong between kamailios? And second question - how to resolve issue with LOCATION table? Thanks

Issue with dlg_setflag vs. setflag
by Anthony Messina 06 Feb '15

06 Feb '15

I'm currently using Kamailio built from master@e59db79 and have been following the recent threads about the dialog module as I'm moving toward adding dialog support for presence and CDRs in my setup. However, I seem to have come across an issue where dlg_setflag() does nothing, while setflag() works properly with the following (trimmed) script. So for now, I issue setflag(FLT_DIALOG) for INVITE rather than dlg_setflag(FLT_DIALOG). Is there something I'm missing about dlg_setflag()? #!define FLT_DIALOG 4 request_route { route(REQINIT); route(NATDETECT); if(is_method("CANCEL")) { if(t_check_trans()) { route(RELAY); } exit; } route(WITHINDLG); if(t_precheck_trans()) { t_check_trans(); exit; } t_check_trans(); route(AUTH); remove_hf("Route"); if(is_method("INVITE|SUBSCRIBE")) record_route(); if(is_method("INVITE")) { setflag(FLT_ACC); # Enable dialog support (dlg_setflag not working) #dlg_setflag(FLT_DIALOG); setflag(FLT_DIALOG); } route(SIPOUT); route(PRESENCE); route(REGISTRAR); if($rU==$null) { # request with no Username in RURI sl_send_reply("484","Address Incomplete"); exit; } route(PSTN); route(LOCATION); route(RELAY); } route[WITHINDLG] { if(!has_totag()) return; if(loose_route()) { route(DLGURI); if(is_method("BYE")) { setflag(FLT_ACC); setflag(FLT_ACCFAILED); # Testing dialog flag xlog("L_INFO", "Completed $dlg(from_uri) to $dlg(to_uri) - $DLG_lifetime duration\n"); } else if(is_method("ACK")) { route(NATMANAGE); } else if(is_method("NOTIFY")) { record_route(); } route(RELAY); exit; } if(is_method("SUBSCRIBE") && uri==myself) { route(PRESENCE); exit; } if(is_method("ACK")) { if(t_check_trans()) { route(RELAY); exit; } else { exit; } } sl_send_reply("404","Not Found"); exit; } -- Anthony - https://messinet.com/ - https://messinet.com/~amessina/gallery 8F89 5E72 8DF0 BCF0 10BE 9967 92DC 35DC B001 4A4E

Best module to use for interrupting a call ???
by Uri Shacked 05 Feb '15

05 Feb '15

Hi, I need to create some kind of check with an application outside of kamailio every X seconds. The check is per call, to get its status or something and according to the result do something with the call (transfer, send info or hangup...). I read about call_control and cnxcc modules. It seems these last ones are to much to do in order to get what i need. Is there a simpler module to use? BR, Uri

Lint and syntax check
by Manuel Rubio 05 Feb '15

05 Feb '15

Hi, I want to know if someone is using something similar to lint-like behaviour[1] and syntax highlighting in editors like Sublime, TextMate, emacs, ... for Kamailio configuration files. [1] http://en.wikipedia.org/wiki/Lint_%28software%29 Thanks. Manuel Rubio.
