[cisco-voip] Polycom Video integrated to Cisco

[Justin Steinberg]

I have a couple of Polycom video units that are currently integrated via PRI
to an Avaya PBX for ISDN access to the PSTN.

C.O.---PRI-----Avaya-------PRI------Polycom (VSX8000)

I am forklifting the Avaya for CUCM. Has anyone used the TDM switching
functionality in the ISR to switch inbound/outbound PSTN ISDN video calls
between pots dial-peers to provide the same functionality on Cisco that is
currently provided by the Avaya PBX?  Any better solution than TDM switching
that works well?

I could always fall back on using an Adtran.  Where the C.O PRIs terminate
to Adtran and the Adtran routes the video DID to the polycom units and
everything else to the CUCM/ISRs.  But I'd rather not use the Adtran if I
can avoid it.

Thanks

Justin
