Accounting: syslog vs db_flatfile
by DanB 19 Dec '14

19 Dec '14

Hey Guys, We are in the process to review the interoperability between Kamailio and CGRateS and was wondering what is the best/most recommended/maintained way to generate accounting from Kamailio: * Syslog * db_flatfile * other way maybe? Is CDR generation planned for files already, or just accounting events? Thanks in advance! DanB

SIP Fragments
by Marc Soda 19 Dec '14

19 Dec '14

I'm having a problem reassembling UDP packets on my Asterisk servers after passing through Kamailio (it appears to me an OS level issue, nothing to do with Kamailio). Is there a way, with Kamailio, to limit the size of a SIP message? I know I can just start removing headers, but that doesn't seem like a realistic solution. I see that Kamailio can compress the message body, but can Asterisk handle that? How do other people handle this? Thanks in advance, Marc

webrtc clients support using rtpengine
by Andrey Utkin 19 Dec '14

19 Dec '14

Hi! I need to establish calls between WebRTC and usual SIP clients (exactly, sipml/jssip and linphone-android). I used configs from https://github.com/caruizdiaz/kamailio-ws and latest git master HEAD of both kamailio and rtpengine. I got calls from webrtc to android working correctly (but only with Firefox browser), even with video. But in other directions i have some issues because of lack of RTP delivery or RTP timeouts. I have some logs to show you regarding this: https://gist.github.com/krieger-od/27c6f3e4924f5e21352e (works), https://gist.github.com/krieger-od/196bcfbd331d621427ef (doesn't work). I would really love to get some quick help from anyone. For direct manual fixing, I can give a couple of hundreds of bucks. Looking forward impatiently for reply from anyone having something to say. -- Andrey Utkin

Kamailio CDRs
by Massimo Varriale (IPZeta) 18 Dec '14

18 Dec '14

Hi Guys! I'm trying to store CDRs for Kamailio calls. Following Siremis tutorial (http://siremis.asipto.com/install-accounting/) I'm able to gather Succesfull Calls and using the MySQL stored procedure I can have a CDR table. But what I can see now is that only outbound calls with a duration are stored and that failed attempts are not stored into the database. How to capture those attempts too? Here is my accounting configuration: # ----- acc params ----- modparam("acc", "early_media", 0) modparam("acc", "report_ack", 0) modparam("acc", "report_cancels", 0) modparam("acc", "detect_direction", 0) modparam("acc", "log_flag", FLT_ACC) modparam("acc", "log_missed_flag", FLT_ACCMISSED) modparam("acc", "log_extra", "src_user=$fU;src_domain=$fd;dst_ouser=$tU;dst_user=$rU;dst_domain=$rd") modparam("acc", "failed_transaction_flag", FLT_ACCFAILED) #!ifdef WITH_ACCDB modparam("acc", "db_flag", FLT_ACC) modparam("acc", "db_missed_flag", FLT_ACCMISSED) modparam("acc", "db_url", DBURL) modparam("acc", "db_extra", "src_user=$fU;src_domain=$fd;dst_user=$rU;dst_domain=$rd;src_ip=$si") modparam("acc", "cdr_enable", 1) #!endif Thanks Max

Any extension or solution on how to implement RPC over SIP
by Thierry Luo 18 Dec '14

18 Dec '14

Dear all, I'm trying to design a SIP based framework that can execute RPC end-to-end. Session is set up based on SIP, and then one user agent can remote call a method into the peer user agent. Anyone have any solution on this? Thanks. Best Regards. Thierry Luo

Maintenance work on kamailio.org - Wed, Dec 17
by Daniel-Constantin Mierla 17 Dec '14

17 Dec '14

Hello, on Wednesday (Dec 17) late afternoon in Europe (probably starting around 18:00, Berlin time), we plan some maintenance work on kamailio.org server. Hopefully the downtime will be short and barely noticeable. But as we know, sometime we have to expect the unexpected, therefore in case the server is unavailable a bit longer, keep in mind that it is a scheduled work. Cheers, Daniel -- Daniel-Constantin Mierla http://twitter.com/#!/miconda - http://www.linkedin.com/in/miconda

bug in allow_source_address?
by Henry Fernandes 17 Dec '14

17 Dec '14

I¹m using allow_source_address in my Kamailio config and have been for months/years. I¹ve had no issues with it until today. The issue is that allow_source_address("1²) returns ³1" (for $si=123.17.29.201 and $sp=5060) even though we don¹t have this IP address in the address¹ table for group 1. We have defined this IP address for group 2 but not group 1. select * from address order by mask; +----+-----+---------------+------+------+----------+ | id | grp | ip_addr | mask | port | tag | +----+-----+---------------+------+------+----------+ | 20 | 1 | 123.17.0.0 | 23 | 5061 | Testing | | 22 | 1 | 123.17.0.0 | 23 | 5062 | Testing | | 23 | 1 | 123.17.0.0 | 23 | 5063 | Testing | | 24 | 1 | 123.17.0.0 | 23 | 5064 | Testing | | 1 | 1 | 123.17.0.0 | 23 | 5060 | | | 4 | 1 | 20.5.176.0 | 24 | 5060 | | | 21 | 1 | 123.17.1.235 | 32 | 5060 | Override | | 46 | 2 | 123.17.29.201 | 32 | 5060 | customer | +----+-----+---------------+------+------+----------+ Can anyone explain this? I¹m wondering if there¹s a bug in how allow_source_address does its net mask calculations. -H
