[Kamailio-Users] Perl module and memory leak in append_branch
by James Puckett 26 Aug '09

26 Aug '09

I have followed a bit of the discussions regarding the problems with memory management between the perl modules and the core kamailio software. I need to get append_branch working from within the perl module so that it doesn't cause a memory leak. It's been a while since I did any serious straight C programming, but if someone can point me to the correct way to handle memory allocated with the module so that it gets freed in the core I'd be glad to take this problem on. Specifically, I'm using something that looks like: $m->append_branch("<sip:".$cdpn."\@".$peers{$_}."?From=%3Csip:". $sourcenumber."@".$destIp."%3E;tag=".$fromtag.">", $qval); This leaves about 190 bytes per call unfreed.

[Kamailio-Users] What happens with filled htables?
by catalina oancea 26 Aug '09

26 Aug '09

Hello I use the htable module a lot but the only problem, when I add a new entry in a htable, is when I will delete it. My question is: if the hash table is completely filled and I try to add a new value to it, do I get an error or is an old value automatically deleted to be able to write my new value? If an old value was automatically deleted whenever a new value is added, I wouldn't have to bother deleting the values I no longer need. Thanks Catalina

[Serusers] problems with stun using uas
by lorenzo 25 Aug '09

25 Aug '09

hi! i'm the developer of a sip app that happens to be connecting to a sip server that's using SER. i'm having troublewith the way SER handles incoming calls to my stun-enabled ua (which is placed behind a router) I have two clients running on the same machine. one is my app, the other is Gizmo5. when i make an outgoing call from my app to the user i'm logged in with in Gizmo5, everything works. but when i call my app from the Gizmo5 app, sniffing the network traffic with wireshark, the only thing i see happening is the sip server sending a 100 Giving a try to the calling ua. The reason i'm posting this here, is that i know it's not a bug with my app, since everything works fine when i don't use stun. (note that i don't have direct access to ser's configuration) this is my app's REGISTER request (note that it has a *public ip*): REGISTER sip:proxy01.sipphone.com SIP/2.0 Via: SIP/2.0/UDP 93.148.135.54:5060;rport;branch=z9hG4bK70207 Max-Forwards: 70 To: <sip:asymmetric@proxy01.sipphone.com> From: <sip:asymmetric@proxy01.sipphone.com>;tag=z9hG4bK57274073 Call-ID: 557402852938(a)93.148.135.54 CSeq: 2 REGISTER Contact: <sip:asymmetric@93.148.135.54:5060;transport=udp> Expires: 3600 User-Agent: mjsip stack 1.6 Authorization: Digest username="asymmetric", realm="proxy01.sipphone.com", nonce="xxx", uri="sip:proxy01.sipphone.com", algorithm=md5, response="yyy" Content-Length: 0 and the response: SIP/2.0 200 OK Via: SIP/2.0/UDP 93.148.135.54:5060;rport=12810;branch=z9hG4bK70207 To: <sip:asymmetric@proxy01.sipphone.com>;tag=92390300a369f0d75803e369c733575e.50aa From: <sip:asymmetric@proxy01.sipphone.com>;tag=z9hG4bK57274073 Call-ID: 557402852938(a)93.148.135.54 CSeq: 2 REGISTER Contact: <sip:asymmetric@93.148.135.54:5060;transport=udp>;expires=3600 Content-Length: 0 Gizmo5's app REGISTER request: REGISTER sip:proxy01.sipphone.com SIP/2.0 Via: SIP/2.0/UDP 192.168.1.100:64064;branch=z9hG4bK-d87543-bbc1e2712d417352-1--d87543-;rport Max-Forwards: 70 Contact: <sip:17474492586@93.148.135.54:10251> To: <sip:17474492586@proxy01.sipphone.com> From: <sip:17474492586@proxy01.sipphone.com>;tag=f43be43c Call-ID: b1b4a060512d4b0c1250955005@YXN5bW1ldHJpYy5sb2NhbA..

[Kamailio-Users] kamailio 3.0 - the time before freezing
by Daniel-Constantin Mierla 25 Aug '09

25 Aug '09

Hello everybody, during the last IRC devel meeting, we pinned end of summer to be the time to enter testing phase for the new major release - codenamed kamailio 3.0. There was quite a lot of brand new features, considering that most of devel effort was directed to integration. A try to collect new items is available at: http://sip-router.org/wiki/features/new-in-devel Of course, all ser features are available as well, resulting a large amount of new stuff in kamailio 3.0 vs kamailio 1.5.x. See: http://sip-router.org/benefits/ http://www.iptel.org/ser/features I propose to start the testing phase sometime next week. Meanwhile, let's see if something important was forgotten from kamailio core or tm. To my knowledge: - path support in tm - Andrei has it on his todo afaik - in a way or another, it must get in next release - drop compatibility - drop reply in reply_route - internally drop and exit are now differentiated by core, needs review and update of handling after running the routes - on my to-do Apart seas, all Kamailio modules are fully ugraded to new core - I started but lack of test env + busy summer resulted in delays - can be done during testing period, being just api updates. If you have discovered something else, let us know. Thanks, Daniel -- Daniel-Constantin Mierla * http://www.asipto.com/

[Kamailio-Users] exchanging CDR data between Asterisk servers
by Klaus Darilion 24 Aug '09

24 Aug '09

Hi! I have the following setup: PSTN<------>Asterisk<-----SIP-->Asterisk GW/LCR \ \ ... \ \ ... \ --SIP-->Asterisk \ ... ------->Asterisk The GW-Asterisk just does the gatewaying stuff and writes the CDRs for the billing system. The other Asterisk servers handle all the services (IVR, REGISTER, ...) Some scenarios require to write some additional data to the CDRs. For outgoing calls this is not a problem (I signal the extra data in a SIP header and set a CDR() variable in the GW asterisk). My problem are incoming calls. The "extra data" is only known to the service Asterisk, but the CDR is written by the GW Asterisk. Does anybody know a method how to signal the "extra data" during the call from the server Asterisk back to the GW Asterisk und put it into a CDR() variable? Regards Klaus

[Kamailio-Users] TLS TCP error
by shehzad p 24 Aug '09

Hello, My Kamailio (tls version) is configured to handle TCP as well as TLS traffic. Making calls from softphone using TCP only works fine. But my TLS traffic has been stucked. I can see lots of error as below in messages file: ====================================================================== Aug 24 06:05:01 ns110 /usr/local/sbin/kamailio[24273]: ERROR:core:tcpconn_connect: tcp_blocking_connect failed Aug 24 06:05:01 ns110 /usr/local/sbin/kamailio[24273]: ERROR:core:tcp_send: connect failed Aug 24 06:05:01 ns110 /usr/local/sbin/kamailio[24273]: ERROR:tm:msg_send: tcp_send failed Aug 24 06:08:10 ns110 /usr/local/sbin/kamailio[24273]: ERROR:core:tcp_blocking_connect: poll error: flags 18 Aug 24 06:08:10 ns110 /usr/local/sbin/kamailio[24273]: ERROR:core:tcp_blocking_connect: failed to retrieve SO_ERROR (110) Connection timed out Aug 24 06:08:10 ns110 /usr/local/sbin/kamailio[24273]: ERROR:core:tcpconn_connect: tcp_blocking_connect failed Aug 24 06:08:10 ns110 /usr/local/sbin/kamailio[24273]: ERROR:core:tcp_send: connect failed Aug 24 06:08:10 ns110 /usr/local/sbin/kamailio[24273]: ERROR:tm:msg_send: tcp_send failed Aug 24 06:08:25 ns110 /usr/local/sbin/kamailio[24279]: ERROR:core:_tls_read: something wrong in SSL: 5 Aug 24 06:08:25 ns110 /usr/local/sbin/kamailio[24279]: ERROR:core:tcp_read_req: failed to read Aug 24 06:09:00 ns110 /usr/local/sbin/kamailio[24277]: INFO:core:tls_accept: client did not present a certificate ================================================================================= I am very confused, because with the same configuration, another kamailio server works very well without any error.

Hello, there is a new PV class that provides access to SER select variables. A list with available selects can be found at: http://sip-router.org/wiki/cookbooks/selects/devel Therefore, all Kamailio modules relying on PV framework can get access to select values without any change. See example of usage from config at: http://sip-router.org/wiki/cookbooks/pseudo-variables/devel#selects Cheers, Daniel -- Daniel-Constantin Mierla * http://www.asipto.com/
