[Serusers] Using SER with Microsoft OCS 2007

[Nolan Garrett]

Hello!

I am interested in using SER to convert TCP SIP traffic from OCS to UDP
SIP traffic that I can use with an external PSTN gateway provider.  Has
anyone successfully managed this?  Basically, the configuration would
look like

OCS -> Mediation Server -> SER -> External Provider

Would the Mediation Server still need an external (non-NAT'd) IP? It
seems like it would, unless I use mediaproxy or RTPproxy, which would
add an additional layer of complexity.

I guess I am looking for some validation that what I am trying to do
will work.  My next question, which I can't seem to find an answer to,
is how I take the TCP SIP traffic from OCS, convert it to UDP SIP, and
also authenticate with that external provider.  Any ideas on how to use
t_relay_to_udp with authentication?

Thank you!
