Hi all I’m trying to create a relatively simple setup with Kamailio dual homed on public/private ip and asterisk on private ip only. The idea is load balance / fail over asterisk boxes. Following the real-time tutorial I have clients registering with Kamailio, Kamailio registering on clients behalf with asterisk as well as invites going through. However what I’m seeing is that when an invite occurs asterisk offers media on its private ip, as it would. However this is making its way through Kamailio all the way to the client. After a bit of searching all I can find is people trying to get it working and failing, or putting asterisk on public IP. So questions - am I doing this completely the wrong way? Should Kamailio alter the media ip of asterisk on the way through or do I need to do that by hand? Surely someone somewhere has a write up on this already :-) Thanks Mark

SEMS with sbc application

by Mojtaba

Hello, I have a problem today, It's strange for me. Suppose we have this senario: uac1------->SEMS(mo profile)------->Kamailio-------->SEMS(mt profile)---------->uac2 In above topology, we have two interfaces(intern,extern) for SEMS, and just used as SBC (sbc application). if i used port=5060 as external port, every things is right and log file is like this: [#7fed3f9f9700/32820] [run, udp_trsp.cpp:352] DEBUG: vv M [|] u recvd msg via UDP from 89.165.117.125:42411 vv --++-- REGISTER sip:kava.shatel.ir;transport=UDP SIP/2.0 Via: SIP/2.0/UDP 89.165.117.125:42411;branch=z9hG4bK-d8754z-021bd8b61efc7ac0-1---d8754z- Max-Forwards: 70 Contact: <sip:4000@ 89.165.117.125:42411;rinstance=79011092e56e1a09;transport=UDP> To: <sip:4000@kava.shatel.ir;transport=UDP> From: <sip:4000@kava.shatel.ir;transport=UDP>;tag=82820e1f Call-ID: Y2U4YThiYjEwNTUzMzliZTIwNWZkMDI3MTM4OTZlNWU.

I just changed external port=4080 in sems server. In SDP protocol i have the same problem when i changed external ip port in sems server. Thanks. --Mojtaba Esfandiari.S

Transcoding

by Wilkins, Steve

Hello All, I am currently using Kamailio and Asterisk on Centos 7 servers and trying to enable WebRTC jsSIP clients to be able to do Audio/Video calls with Provider Phones (Purple, Z, Sorenson, etc....), however, the providers do not have vp8 codecs (which is what the WebRTC clients use for Audio) so I believe I will need a media proxy server to resolve the video issues. My question is, can rtpproxy or rtpengine perform this transcoding? If so, and if rtpengine is the way to go, should I use Ubuntu for the rtpengine since it is the only one that seems to have a working installation? Thank you, -Steve

EOL of geoip module.

by Sergey Okhapkin

Maxmind just announced EOL of legacy geolite databases used by geoip module, no updates starting this April. See more at https://blog.maxmind.com/ 2018/01/02/discontinuation-of-the-geolite-legacy-databases/ If you use kamailio's geoip module, I suggest to switch to geoip2 module which uses Geolite2 databases and is a plug in replacement for geoip module.

Hey everyone. Right now i'm doing a redirect server and i'm trying to sinalize the redirection using a 3xx reply. In order to do that, according the RFC I need to add a Contact and Diversion header. How do i do that ? i'm creating the reply with send_reply() but i can't seem to find a way to add these parameters to the reply. Thanks for the help. Cheers
