Hello All, I have the following SDP coming in from a carrier and would like to remove the following line.

Core crash in del_lump() "offset exceeds message size" when using subst() inside tm:local-request route.
by Cody Herzog 08 Aug '17

08 Aug '17

Hello. Inside the tm:local-request route, I am trying to modify the body of outgoing NOTIFY messages using the subst_body() function. Things seem to work fine most of the time. The NOTIFY messages are correctly modified. However, I will very rarely hit a crash. I can force the crash to happen more quickly by stress testing with thousands of NOTIFY messages being modified. Is it safe to call subst() or subst_body() inside the tm:local-request route? If not, is there another way I can modify the outgoing NOTIFY messages safely? Note that I am also calling append_hf() inside the same tm:local-request route, but that has been working for a very long time without causing any problems. Could there be some kind of bad interaction between append_hf() and subst_body()? Strangely, it seems like using subst() makes the crash more likely to happen. For some reason, subst_body() seems to be more robust. Here are the logs I see: --------- Jul 28 10:57:40 SIPCOMM-VEGAS-TEST /usr/local/sbin/kamailio[2476]: CRITICAL: <core> [data_lump.c:292]: del_lump(): offset exceeds message size (1625 > 1194) aborting...

kamailio + dispatcher asterisks + pstn gateways
by Aidar Kamalov 08 Aug '17

08 Aug '17

Hello, Whats the best way to provide subject? Now I have central kamailio server and (asterisk "media" servers + asterisk pstn gateway in different cities). Kamailio default config with some changes in route[LOCATION] if (!lookup("location")) { $var(rc) = $rc; route(TOVOICEMAIL); t_newtran(); switch ($var(rc)) { case -1: xwarn("Contact $rU not registered. Forwarding call to dispatcher"); append_hf("X-External: true\r\n"); $rU = "00"+$rU; break; case -3: send_reply("404", "Not Found"); exit; case -2: send_reply("405", "Method Not Allowed"); exit; } } ...... # when routing via usrloc, log the missed calls also if (is_method("INVITE")) { setflag(FLT_ACCMISSED); } if(!ds_is_from_list()) { route(DISPATCH); } route(RELAY); So all calls going to asterisk server. Not local calls with 00 prefix. And asterisk context: context kamailio { _X. => { Noop(CALL to kamailio user ${EXTEN}); Dial(SIP/${EXTEN}@${SIPDOMAIN},60,RTt); Hangup; } _00X. => { Noop(CALL to external user ${EXTEN}); Dial(SIP/PSTN-SERVER/${EXTEN:2},60,RTt); Hangup; } } Is it right way? Maybe any better approach? How to keep route logic at kamailio, but use dispatcher asterisk to proccess the calls to pstn(all endpoints at one city to pstn asterisk at this city. In others city there are other pstn gateways)? -- Aydar A. Kamalov

Kamailio Server not relaying any message
by Rahman Afzal 08 Aug '17

08 Aug '17

Hi, I have an ongoing issue with kamailio...my softclient registered with kamilio originates a call which gets routed to another switch from kamilio and that switch terminates the call to B party side. Now once calls is established, B party sends BYE messages or (any re-INVITE during the dialog) which comes to the kamailio but kamailio is not relaying it to the A party...Can someone please help in this regard. Regards, Abdul Rahman
