Need help in routing configuration
by Nelson Pereira 20 May '10

20 May '10

I have the bellow setup for openser, yet this wont work in Kamilio. Wondering if anyone could help to make this routing code work? What Im looking to do is receive Invites in UDP and relaying it via TCP.... route{ if (!mf_process_maxfwd_header("10")) { sl_send_reply("483","Too Many Hops"); exit; }; if (msg:len >= 2048 ) { sl_send_reply("513", "Message too big"); exit; }; if (loose_route()) { append_hf("P-hint: rr-enforced\r\n"); route(1); }; if (!uri==myself) { append_hf("P-hint: outbound\r\n"); route(1); }; route(1); } route[1] { if (src_ip==10.98.6.5) { if (dst_port==5060) { t_relay("tcp:10.98.118.20:5060"); } if (dst_port==5065) { t_relay("tcp:10.98.118.20:5065"); } else if (dst_port==5066) { t_relay("tcp:10.98.118.20:5066"); } else if (dst_port==5067) { t_relay("tcp:10.98.118.20:5067"); } # else { # t_relay("tcp:10.98.118.20:5060"); # } } else { t_relay("udp:10.98.6.5:5060"); }; } Nelson Pereira Senior Network Specialist Protus<http://www.protus.com/> npereira(a)protus.com<mailto:name@protus.com> phone: 613.733.0000 ext.528 MyFax: 613.822.5083 MyFax.com<http://www.myfax.com/> | my1voice.com<http://www.my1voice.com/> | Campaigner.com<http://www.campaigner.com/>

allow_trusted() use.
by Vicente 20 May '10

20 May '10

Good afternoon, I'm trying to configure permissions module to allow calls from an IP address. I've the module loaded, the entry on the data base table trusted. But according to the examples I've seen on the list and other sources, the call to allow_trusted() has to be placed just before the INVITE authorization section like: if (is_from_local()){ if(!allow_trusted()){ ...authorization... In my scenario allow_tusted() is never reached and thus Kamailo allows the call regardless the table trusted is populated with the the allowed proxy IP or not. The INVITEs that I want to allow come from another proxy and then I understand is_from_local() is always evaluated false for those messages. And allow_trusted isn't reached. Where on the script should the condition to allow only the calls from the external proxy IP be placed? Thanks in advance. Vicente.

Routing problem
by alet＠librelogiciel.com 19 May '10

19 May '10

Hi, First I'm a complete SIP newbie. We've purchased a new pabx which is a complete piece of crap (Alcatel OmniPCX OXO) : no LDAP support, no registrar functionnality, and so on... and it seems there's no way to upgrade. This pabx is on a subnet different from the one used by desktop computers. What I'd like to achieve is to be able to install SIP soft phones onto desktop computers (like ekiga for example), allow them to call all non-IP phones already configured in the pabx, and be called by any non-IP phone through the pabx. Since the pabx doesn't have a registrar mode, it can't associate IP addresses with phone numbers. So in ekiga, I can configure the pabx as a SIP proxy, and my ekiga can call any normal (non-IP) phone connected to the pabx. This works fine, but is only one half of what I want, since I want these SIP phones to be callable from non-IP phones. Enters openser, which I plan to use as a registrar and router. So I've installed openser 1.3.2 onto a Debian Squeeze box. I can successfully register SIP soft phones to it, and they can call each other just fine calling (number(a)sip.example.com). This openser box is on the same subnet as the Alcatel pabx (so different from the one used by SIP soft phones). All our "normal" phone numbers are 6 digits long and begin with 290, so I want to route all call numbers beginning with "290" to the Alcatel pabx. So I've modified the default openser.cfg to contain : --- CUT --- port=5060 listen=udp:10.125.0.1:5060 ... route { ... if (is_method("INVITE")) { setflag(1); if (uri=~"sip:290[0-9]{3}@sip.example.com") { xlog("#### CALL TO NON-IP PHONE ####\n"); route(2); } } ... } ... # route[1] was in original openser.cfg route[1] { # for INVITEs enable some additional helper routes if (is_method("INVITE")) { t_on_branch("2"); t_on_reply("2"); t_on_failure("1"); } if (!t_relay()) { sl_reply_error(); }; exit; } # # I've added the following route[2] { rewritehostport("pabx-alcatel.example.com:5060"); xlog("#### Server and port rewritten ####\n"); route(1); }... --- CUT --- Now in ekiga if I dial sip:number@pabx-alcatel.example.com:5060 it works fine as it always did, because this call is direct. However if I dial sip:number@sip.example.com:5060 the host and port in URL are correctly rewritten in sip:number@pabx-alcatel.example.com:5060 but nothing happens : the call doesn't ring and fails immediately. In the logs when dialing sip:290081@sip.example.com:5060 I've got this, so I suppose it *SHOULD* work : --- CUT --- /usr/sbin/openser[759]: #### CALL TO NON-IP PHONE #### /usr/sbin/openser[759]: #### Server and port rewritten #### /usr/sbin/openser[759]: new branch at sip:290081@pabx-alcatel.example.com:5060 /usr/sbin/openser[760]: incoming reply /usr/sbin/openser[758]: incoming reply --- CUT --- but it doesn't work as expected. any idea why ? NB : I understand this would only solve half of my problem, the other part will be solved (I hope) with the help of the guy who installed the pabx. Thanks in advance Jerome Alet

Siremis - missing cdr calcs and repeats
by Anders 19 May '10

19 May '10

Hi, I'm having some challenges with Siremis, and it says on the project website that this list is the place to ask - so here are the two issues: 1. Repeats: I had problems with repeats in the cdrs table. This was possible, because I had forgotten to set the correct unique index (call_id + from_tag + to_tag). Once this was set, it was obviously not possible to make the repeats anymore - so problem solved. But I still wonder: why was it trying to calculate calls that had already been calculated? Shouldn't it ignore these and only treat new ones? 2. Missing calcs After an unsuccessful attempt to upgrade MySql from 5.0 to 5.1, it seems that not all calls are being calculated and put in the cdrs table. The CRON job was stopped due to the failed upgrade of MySql, but I started it again later - MySql was not down. However, I thought it would 'catch up' with the transaction that had not been calculated while the CRON job for the stored procedure had been off, but it did not. In fact, it seems that not all calls are being calculated and put inthe cdrs table - I'm missing almost half the calls. Any idea what this can be? Thanks!! //Anders

Kamailio 1.5 stops processing messages
by Santiago Gimeno 19 May '10

19 May '10

Hi, I'm working with Kamailio 1.5 (rev 5968) and from time to time kamailio freezes and stops processing messages. Kamailio is working only in UDP. I really don't know in which conditions this problem is happening: it happens both in high and low load. Here is a backtrace of one of the UDP working processes when kamailio is frozen (all the other UDP process backtraces look similar) : #0 0xb7fdf410 in ?? () #1 0xbfbfec28 in ?? () #2 0x00000001 in ??

Robust header compression (RFC 3095) with Kamailio + rtpproxy
by Vikram Ragukumar 18 May '10

18 May '10

Hello, We are looking into bandwidth conservation by implementing RTP/UDP/IP header compression. Has anybody implemented ROHC or another header compression scheme in combination with kamailio + rtpproxy ? Could you please point us to online documentation or other useful resources ? Thanks and Regards, Vikram.
