I use a general context in asterisk to route calls already and wanted to get away from pattern matches. I'm using asterisk realtime and want to decrease the load. I'll play around with the 'uac_replace_from()' and 'append_hf' to see what works best for me. I really appreciate your quick response, very insightful. Thanks.

add fromuser to sip request
by JR Richardson 05 Oct '10

05 Oct '10

Hi All, I am using Kamilio 3.0.2 as a load balancer in front of Asterisk servers, using Dispatcher/PDT and such, working fine. I would like to be able to bring sip calls into Asterisk at different entry points in the dialp plan, so I want to setup sip users; [sipentry1] contex=blah, [sipentry2] context=blahblah. In Kamailio, how would I go about receiving a sip request, append a user "sipentry1" then forward it to Asterisk? I would be using some sort of trunk prefix to identify which sip request to append the user like: 552145551212@siprouter, strip 55, append user "sipentry1", dispatch t-relay to asterisk 562145551212@siprouter, strip 56, append user "sipentry2", dispatch t-relay to asterisk 572145551212@siprouter, strip 57, append user "sipentry3", dispatch t-relay to asterisk Any point in the right direction will be appriciated. Which module should I be looking into? Thanks. JR -- JR Richardson Engineering for the Masses

Tutorial: SIP SIMPLE Presence Made Simple with Kamailio 3.1
by Daniel-Constantin Mierla 05 Oct '10

05 Oct '10

Hello, I published a tutorial of how to implement a SIP SIMPLE Presence & XCAP server with latest Kamailio/SER version. You can find it at: http://bit.ly/btrJij Last build of SIP Communicator softphone was used to exemplify some use cases. xcap_server is a new module in upcoming v3.1.0, I have tested it with several SIP clients, but I have to say is not easy to find one that implements many presence & xcap extensions (filled already couple of bugs so far). So consider it a young component by now, however, with it inside our SIP server, deploying a SIP presence server becomes trivial. Hope is helpful, Daniel -- Daniel-Constantin Mierla http://www.asipto.com

retrieve INVITE transaction in CANCEL
by Zappasodi Daniele 05 Oct '10

Hello, is it possible to retrieve the info related to the INVITE transaction while the CANCEL is processed? In particular, when the script is handling the CANCEL, how can I get the avp values written in the corresponding INVITE transaction?

Re: [SR-Users] Error on radius accounting
by Asim Riaz 04 Oct '10

Hi List, Having an issue with my freeradius, I am getting below errors when kamailio sends radius records and freeradius try to store into database; Error: Ignoring request from unknown client 192.168.1.100:1814 Radius client and server are running on the same machine and I have necessary configuration in clinet.conf and server.conf for localhost and I can see radius is writing record for the calls but looks like radius client is trying to send record twice one from localhost and one from the interface ip? Error: Rejecting request 88 due to lack of any response from home server OpenSER:5061 Proxy: marking accounting server 192.168.1.100:1813 for realm DEFAULT dead Proxy: marking accounting server 78.137.190.133:1813 for realm DEFAULT dead Error: rlm_sql (sql): Couldn't insert SQL accounting START record - Duplicate entry 'fdeb080-b342ea59-13c4-50022-17bee27-76d4b161-17bee27-fc5b7f8-b34' for key 'sess_id' Error: rlm_sql_mysql: Cannot store result As the radius record being store in the database so looks like its trying to record the same data twice and because the this record already in the database its failing to record the data. I know this is more related to freeradius but I am just wondering if someone experienced the same problem and how it was resolved Thanks, Asim

by X- x -X 04 Oct '10

04 Oct '10

Hey Jon, I gather you are the man when it comes to packaging the goods. My query: Building packages for a distribution yields in the end packages with this 3.0.2.99 version. How come ? shoudn't it be 3.1.x (source pulled from git repo of kamailio 3.1) Anyway how are there any test packages out there to be tested before releasing on 6 th ? Thanks --

"Create Certificates to be used with Kamailio" changes
by Juha Heinanen 04 Oct '10

04 Oct '10

now that 3.1 has async tls support, i decided (first time ever) to try to test tls. things went quite smoothly when i followed "Create Certificates to be used with Kamailio" document http://kamailio.org/dokuwiki/doku.php/tls:create-certificates#using_the_cer… during the process, i fixed a typo in the doc, added two comments to cfg part: enable_tls=1 tcp_async=no # do not include in 3.1 listen=udp:0.0.0.0:5060 listen=tcp:0.0.0.0:5060 listen=tls:0.0.0.0:5061 # not needed in 3.1 and fixed wrong file references in client configurations: eyebeam: copy the CA certificate (/etc/certs/demoCA/cert.pem) to the Windows PC and add it to the Windows certificate store (Start→Control Panel→Internet) QjSimple: copy the CA certificate (/etc/certs/demoCA/cert.pem) to the client PC and configure QjSimple to use this CA (“TLS CA file” and “verify TLS server certificate) earlier the paths pointed to certs/sip.mydomain.com files, which i think were wrong. at least i was not able to get them working. perhaps someone who is more familiar with tsl stuff could verify the above changes. -- juha

correct way to define flags in Kamailio 3.0.3
by Andrew Pogrebennyk 04 Oct '10

04 Oct '10

What is the correct way to write flags in Kamailio 3.0.3? I've tried both enum-like way: "flags a, b;" and the macro way: "#!define a 1", but neither has worked. I'm getting a syntax error trying to used defined flag, e.g.: modparam("usrloc", "nat_bflag", FLB_NATB) In 3.1 though the macro works fine. -- Sincerely, Andrew Pogrebennyk
