Hi,
I am just getting started with Kamailio and have been following the book
"Building Telephony Systems with OpenSER" by Flavio E. Goncalves. The
book describes an architecture with a SIP Proxy handling registrations
and handing calls to a PSTN Gateway. I now have a basic test network
running where calls are routed via the SIP Proxy (Kamailio) to a third
party PSTN Gateway. I feel that a better design would be to implement my
own PSTN Gateway using Kamailio. This single gateway would then handle
all third party PSTN gateways. Thus one Kamailio server would be facing
my clients while another would be facing my suppliers.
Is this a sensible architecture and are there any sample configurations
for Kamailio performing this role?
It depends on what features you need facing the gateway providers. Eg.
if the gateway provider uses digest authentication then you may run into
problems with Kamailio. Many people use a B2BUA as "fake" gateway to
have full control over the call (e.g. Asterisk, sems, sippy)
