t_check_status documentation
by Eric Hiller 06 May '11

06 May '11

One thing that really threw me this morning was the lack of t_check_status in the modules documentation. Apparently it is still there and works, just completely undocumented. Once I realized it was still there I just went back to the 1.5 docs and was good, but just thought I should point this out. -Eric

db_text issue
by Eric Hiller 06 May '11

06 May '11

I would like to use dbtext to store a list of whitelisted gateways, but each time I load it I get a core segmentation fault. Any ideas? Here is my gateways db file: key_name(str) key_type(int) value_type(int) key_value(str) gwip:1:0:a gwip:1:0:b gwip:1:0:c gwcount:0:1:3 And in my config: modparam("htable","htable","gateways=>size=4;dbtable=gateways;") modparam("htable","db_url","text:///usr/local/etc/kamailio") while( $var(i) < $sht(gateways=>gwcount) ){ if( $sht(gateways=>gwip[$var(i)]) == $si ){ setflag(gateway); xlog("ISFROMGW: request from IP $si matches $sht(gateways=>gwip[$var(i)]) ...\n"); } } Do you see anything wrong with this setup? -Eric

Force RTPProxy
by Simone Felici 06 May '11

06 May '11

Hello to all! I need a little help with our ser installation (ser-2.0.0-rc1). Due some network restrictions, we need to force every call to pass trought rtpproxy. Could someone point me to the right place where to force it? Please an example based on our config would be really helpful, but in two scenarios: 1. ALL CALLS trought rtpproxy 2. ONLY CALLS from a given network trought rtpproxy We are in doubt on what choose between the two solutions. Having both examples could me help to implement the needs faster :) Thank's a lot for your help! Simon

Calling t_on_reply in branch_route doesn't work in Kamailio 3.1 - did work in Kamailio 1.5
by Sebastian Damm 05 May '11

05 May '11

Hi, I'm currently migrating a Kamailio 1.5 installation to Kamailio 3.1.3, and I got all config changes merged, except this one: branch_route[1] { if ((isbflagset(4)) && (!isflagset(7))) { fix_nated_sdp("1"); if (has_body()) { force_rtp_proxy("R"); } else { setflag(5); } t_on_reply("2"); } } In Kamailio 1.5 this worked without problems. In Kamailio 3.1 I get the following error (line 1627 is the line with t_on_reply on it): hostname:~# /usr/sbin/kamailio -c -f /etc/kamailio/proxy/kamailio.cfg loading modules under /urs/lib/kamailio/modules/:/usr/lib/kamailio/modules_k:/usr/lib/kamailio/modules_s/ 0(13670) : <core> [cfg.y:3412]: parse error in config file /etc/kamailio/proxy/kamailio.cfg, line 1627, column 17: Command cannot be used in the block ERROR: bad config file (1 errors) hostname:~# In the Kamailio 1.5 documentation it was stated for every t_on_* function, where it could be called. For t_on_reply it said: This function can be used from REQUEST_ROUTE, BRANCH_ROUTE, ONREPLY_ROUTE and FAILURE_ROUTE. In the Kamailio 3.1 documentation those lines are missing. But I don't really see a reason, why t_on_reply shouldn't be called from branch route. We need it for every branch to possibly have different onreply_routes. Am I missing something? Thanks in advance for any hints. Best regards, Sebastian

Re: [SR-Users] Kamailio lib/srdb1/db_id.c handling of multiple database connections and race condition
by Robert Verspuy 05 May '11

05 May '11

Hi Torge, I think it's better to send your mail to the mailinglist, then more people can have a look at your problem. I'm not really familiar with the kamailio source code. Just started using Kamailio about 8 months back. I came across a problem with requesting information from a postgresql database and made a patch which 'works for me'. I'm not using siptrace. Maybe you can supply more logging (through the mailinglist) of the database communication. The mysql error "Duplicate entry '96193' for key 'PRIMARY'" is a bit weird. As I said, I don't know and don't use the msyql driver in kamailio, but normally I would expect that mysql itself would take care of generating a primary key for the record. So maybe your problem is in the mysql server and not kamailio. Maybe this page can help you: http://www.softwareprojects.com/resources/programming/t-how-to-fix-mysql-du… With kind regards, Robert Verspuy Op 05-05-11 13:19, Dr. Torge Szczepanek schreef: > Hi! > > First of all thanks for all of your work.

Rtp Port Question
by Sungjin Park 04 May '11

04 May '11

Hello, I use your sip service well. But there is one problem occured. I use your sip service on my android system. The application is Csipsimple. On Wifi and 3G connection, your service is very good. your sip account did good work. even 3G network connection. Btw, On Mobile Wimax service, the signal was good. But the Voice could not be trasnsferred. I guess the problem is about rtp port. *I'd like to know the rtp port that IPTEL use*. I will request Korea Telecom about rtp port open. Korea Telecom is Korean mobile Wimax Provider. Thank you. Sungjin Park Seoul, Korea
