Hello everyone...

I'm testing various ways of setting up Kamailio and FreeSWITCH (as VAS-handler).

I'm struggling a bit on what Kamailio should do and FreeSWITCH should do.

My basic setup is to handle voicemails, internal calls between subscribers and outgoing calls to a SIP gateway to GSM.

My idea is to have Kamailio handle all calls and routing between subscribers and the SIP gateway and only have FreeSWITCH handle voicemail (to save the audio file and e-mail it).

How does that sound?

Or should I route everything to FreeSWITCH via Kamailio and have FreeSWITCH route calls between subcsribers and SIP gateway as well?

What are best practises etc...?
