[asterisk-biz] asterisk and kamailio realtime integration tutorial

[Daniel-Constantin Mierla]

Hello,

I thought this might be interesting for some guys here - I wrote a new 
tutorial about realtime integration of Asterisk and Kamailio (OpenSER), 
it is available at:
https://kb.asipto.com/asterisk:realtime:kamailio-3.0.x-asterisk-1.6.2-astdb

In the past I wrote and maintained Asterisk and OpenSER (then Kamailio) 
relatime integration for various versions, but a different approach, 
published at voip-info.org, like:
http://www.voip-info.org/wiki/view/Realtime+Integration+Of+Asterisk+1.4+With+OpenSER+1.3
http://www.voip-info.org/wiki/view/Realtime+Integration+Of+Asterisk+1.4+With+Kamailio+1.5.x

There is a new approach with latest tutorial. First, the used database 
is Asterisk realtime, not kamailio (openser) database like in old 
tutorials -- this allow to update easily from existing Asterisk 
installations using realtime, keep your GUI to add/remove extensions and 
manage the system.

Second, voice call routing is handled by Asterisk, practically the VoIP 
service goes as you have it configured with Asterisk only (in the old 
tutorials, call routing between users was handled by kamailio (openser), 
Asterisk being used only for several media services, such as voicemail, 
conference, announcement). Therefore you can play audio within each 
call, have customized ringing tones, process DTMF with calls, etc.

Cheers,
Daniel
