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

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.

kamailio passthrough user auth
by Kai Arif 05 Feb '15

05 Feb '15

Hi, I have to implement a rather uncommon SIP setup and wanted to ask, if it is even possible with Kamailio. We are among other things a VoIP-provider for a couple of hundred customers. Right now we use a rather old piece of software as a SIP-server, that was written in-house and is deeply integrated in our user interfaces and the billing system and can't be replaced easily. But now we need to make some modifications because our PSTN-gateway-provider is changing things. The idea is to use Kamailio as proxy in front of our old SIP-server. But to do this we need to pass through the REGISTER requests of our users to the old SIP-server. So the question is if Kamailio supports this kind of passthrough and I would also be rely grateful for a piece of example config, if somebody already has a similar setup running. So far neither the documentation nor google have been very helpful.

Does the event_route[tm:local-request] support stateless forwarding configured in the script?
by Klaus Feichtinger 05 Feb '15

05 Feb '15

Hello, I´m searching for a way to keep track about success or failure of locally generated SUBSCRIBE transactions, which are typically triggered by the RLS module. In case that a subscription is rejected by the subscribee with any negative response code or the transaction is timing out, I have to trigger a specific action (e.g. sending a PUBLISH message to another user agent). This seems to be not so easy.... As Kamailio does not support referencing a failure_route to locally generated requests, I had the idea to "forward()" locally generated requests in the event_route "tm:local-request" to itself and handle the forwarded requests in the standard request_route, which would offer all usual options. But that seems not to be supported / allowed by Kamailio, as I have in practical tests (1) an outgoing request that is sent to the original Destination-URI (with a malformed "Content-Length" SIP hdr) and (2) the second request that is sent to the manual target (loop). I´ve found in the mailing list that elder Kamailio versions did not support any common way for this feature. However, can anybody give m a hint if / how this could eventually be solved with the event_route or in any alternative route? It seems that the Kamailio internally generated requests are still below the radar of TM or any other route blocks except tm:local-request..... regards, Klaus

Out of Memory Error in Kamailio

Hi Guys, I am using Kamailio-4.2.1. Earlier I was using shared memory of 16GB, which started popping out of memory error, within few seconds of generating load from sipp. I used sipp following command: sipp -s 999999999999 MY_KAM_IP -l 2500 -r 50 *Error coming is :* *Feb 4 14:12:23 kamailio_us_ha1 /usr/local/sbin/kamailio[27389]: ERROR: tm [t_reply.c:1946]: relay_reply(): ERROR: relay_reply: cannot alloc reply shmem* After changing the shared memory to 1 GB, this error came quite late when generate load at 200 CPS. sipp -s 999999999999MY_KAM_IP -l 2500 -r 200 Why this is happening?
