Blacklists and DB_Cassandra
by SamyGo 13 May '16

13 May '16

Hi, I am tasked to make use of blacklist module for about 4 to 6 million numbers. I am thinking of using Cassandra for the purpose but reading through the documentatiom of module and recent mailing list discussion made me a bit hesitant. I am looking for advise on this whether this is going to perform as expected or is not even going to work with the BlackListing module ! I am using Cassandra 33x and Kamailio 4.4 over Ubuntu 14.04. Looking for suggestions here. Regards, Sammy

route_if_exists crash / breakage
by Alex Balashov 12 May '16

12 May '16

Hi, I'm running 4.4.0:ea2033 and am seeing a crash when using route_if_exists() on a nonexistent route: Core was generated by `/usr/local/sbin/kamailio -P /var/run/kamailio.pid -m 512 -M 8 -u evaristesys -g'. Program terminated with signal 11, Segmentation fault. #0 0x0000000000456751 in do_action (h=0x7ffcce5bc4c0, a=0xf0f0f0f0, msg=0x7fba440abc80) at action.c:337 337 switch ((unsigned char)a->type){ gdb) print a $1 = (struct action *) 0xf0f0f0f0 (gdb) print a->type Cannot access memory at address 0xf0f0f108 The invocation looks like this: if(check_route_exists("AUX_RTPENGINE_OFFER_INBOUND")) route_if_exists("AUX_RTPENGINE_OFFER_INBOUND"); else { set_rtpengine_set("1"); rtpengine_offer("replace-origin replace-session-connection ICE=remove"); } #route[AUX_RTPENGINE_OFFER_INBOUND] { # xlog("L_INFO", 'action=R-AUX-RTPENGINE-OFFER-INBOUND'); #} Uncommenting the nonexistent route has another curious effect: script execution appears to break after route[AUX_RTPENGINE_OFFER_INBOUND] executes, and nothing further happens. Changing route_if_exists("AUX_RTPENGINE_OFFER_INBOUND"); to route(AUX_RTPENGINE_OFFER_INBOUND); resolves both issues (the crash and the script execution halting). But, of course, if the route is commented out - its normal state - then Kamailio won't start since it won't allow a nonexistent identifier to be passed to route(). -- Alex Balashov | Principal | Evariste Systems LLC 1447 Peachtree Street NE, Suite 700 Atlanta, GA 30309 United States Tel: +1-800-250-5920 (toll-free) / +1-678-954-0671 (direct) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/

Kamailio / issue with registration
by Ali Taher 12 May '16

12 May '16

Hello, I installed Homer with kamailio as capture agent in order to capture sip packets. The first test I did was using the default kamailio.cfg config located in homer-docker directory , where all Register and Invite packets were saved in the database and I was able to monitor them from web homer. After that , I tried to enable registration using the save(location) function in registrar module , yet I'm getting the below error in the log : 2016-05-11T18:48:36.443231+03:00 ubuntu /usr/sbin/kamailio[4759]: ERROR: <core> [udp_server.c:550]: udp_send(): sendto(sock,0x7f64702b1d98,767,0,192.168.26.3:3806,16): Bad file descriptor(9) 2016-05-11T18:48:36.443239+03:00 ubuntu /usr/sbin/kamailio[4759]: ERROR: sl [../../forward.h:201]: msg_send_buffer(): udp_send failed 2016-05-11T18:48:36.443247+03:00 ubuntu /usr/sbin/kamailio[4759]: ERROR: registrar [reply.c:734]: reg_send_reply(): failed to send 200 OK Can you please help with resolving this issue , noting that the registration works good if I remove the routing logic set for sipcapture. Any hint would be appreciated. Cheers, Ali Taher

T_RELAY_TO distribute local proxy to a central one
by Sébastien Brice 12 May '16

12 May '16

Hi guys, i have a kamailio running on the wan (my central kamailio) and i have phones on a private network range 172.20.0.0/16 behind a NAT. i also run another kamailio locally to collect all sip phones on my network and this one use the DB of the remote central kamailio. the local kamailio does t_relay_to() the ip of the central kamailio route { if (uri==myself) { if (method=="REGISTER") { route(2); exit; }; route[2] { rewritehost("public_remote_kamailio"); if(!t_relay_to("udp:public_remote_kamailio:5060")) { sl_reply_error(); }; exit; } the bad thing is once the phones get registered with non-routable ip (like in the attached picture) trying to INVITE them directly by requesting public_kamailio_ip result in non-working situation. how should I rewrite my dst_domain when registring in a way INVITE triggers to the local kamailio. My local kamailio runs with the listen udp:private_local_kamailio advertise udp:public_local_kamailio I try to be explicit but my understanding is not perfect, it would be nice you could give me a hand. I put my local kamailio.cfg attached. thx

speeddial, owners
by Filippo Graziola 11 May '16

11 May '16

Hello everybody, I have a kamailio running on debian, and it works well with a little modification of the kamailio-advanced file. I would like to have some speed dial short numbers for all local users, because I used a random generator script and usernames and password are 25 digits (not only numbers) long. My problem is with the ownership of a every speeddial number. Example: SIP accounts: 5001,5002,5003 SIP domain: mydomain.com add a speeddial number: kamctl speeddial add 5002(a)mydomain.com 51(a)mydomain.com sip:5001@mydomain.com I can call from user 5002 to user 5001 typing 51 correctly. what I would like to do is that sd-id 51(a)mydomain.com could be called from every user registered at mydomain.com. I read the module documentation, kamctl help but I'm not able to find an answer. Could you please help me? Thank you in advance
