[OpenSIPS-Users] Usage of OpenSips as a OCS to PBX Gateway

So here is my usage Senario.....
We have a multiple registration points on a SIP based PBXs and we want to use Microsoft OCS as a Client to the users extensions..
The SIP PBX must have registrations for each extension and does not accept TCP It uses UDP
Microsoft OCS uses a Mediation server and only talks TCP.
So we found working examples of how to make a TCP < - - > UDP Gateway (problem one solved.)
So what I need to do is create a database that contains a list PBX's and the associated E.164 address in OCS
So here is the Senario
OCS Client < - - >
OCS Server < - - >
OCS Mediation Server (next hop to Opensips Server) < - - >
OpenSips Server (registers with each PBX) < - - >
So what I was looking for was a way give a DB list containing
SIPServer SIPUser SIPPassword E.164
Pbx.michigan.anycompany.com 7101 cn4516 +12485558765
Pbx.ohio.anycompany.com 308 jf455k +13805557888
Pbx.florida.anycompany.com 922 ki7633 +13525557455
So functionally each record would connect and register with the associated PBX
Any incoming calls to PBX would be routed to the Mediation server using the E.164 (Let Microsoft figure out what the user based on the E.164)
Any outgoing calls from OCS would connect to the appropriate SIP server.
Sounds like a tall order.
But anyone have any idea if this can be done with Opensips?
Or does anyone have a more elegant solution?
