I'm just starting to evaluate Kamailio to be used
as a front end to a couple of Asterisk Servers.
Currently I have an Adobe Flex application that interfaces with Asterisk via AMI using a
socket connection. I searched on how to interface with Kamailio but wasn't able to
find anything that helped me. I would appreciate it if someone could point me to where I
can find information on how this can be done using Kamailio. For example I would like my
Flex Application to connect to Kamailio to know the status of the SIP channels.
By default, kamailio doesn't have any knowledge about "channel". A SIP proxy
is transaction stageful - in telephony terminology, it knows a call setup or a teardown,
but doesn't have any relationship between them - the idea of a "call" is
lost.
You can make Kamailio call stateful by using the dialog module, but on the other side -
you don't need it since Asterisk is very call stateful. In fact, it makes your
platform less redundant to have call states everywhere.
The interface you are looking for is either the MI interface or the RPC interface. We have
two interfaces that mostly provides the same functionality. Every module has different
functions. It is a simple query-answer interface and has not got the "events"
that you get from Asterisk.
I hope this helps you.
