Hi All,

I would like to setup freswitch and kamailio as follows:

Kamailio acts as Proxy and Registrator
Freeswitch acts as a SBC and MediaServer (voicemail)

Users will be reigstered to Kamailio
Kamailio forwards calls to FS to NAT
FS sends back INVITE to Kamailio
Kamailio will dial-out user.

Bob calls Alice
Bob ==INVITE ==> Kamailio ==INVITE==> FS ==INVITE==> Kamailio ==INVITE ==> Alice

How can I achieve this scenario?  Can you please direct me to any documentation which is available?
Thanks,
Ramu

Yes it is possible but there is no documentation on how to do it. You will have to learn SIP and understand what you are doing.Forwarding the call to FS for nat may cause issue as FS will then not have direct connection to the phone and may not be able to always detect it is behind NAT.
Have a look at SIP PATH Extension as it is what you need to force traffic back to KAM from FS.


Regards,


Thomas
