Thanks for your reply Klaus.

Yes I was not clear... I just meant they wanted to keep the Asterisk server on a different segment for their reasons,
and use a bridge to the Kamailio server.

Very possible.  Once we have it working both ways (with/without bridge), I have a feeling the bridge may cause enough
issues -- or not enough advantages -- and it will be easier to convince them to re-think.

In this setup, can Kamailio allow non-SIP protocols (HTTP, SSH, etc) to pass to the Asterisk server and/or other servers?
