IPVC and Cisco (Tandberg) CP-7985?

I have not seen the 7985 in use with a MCU, and wanted to verify it would work. Customer also has Polycom MP Viewstations (H323), with IPVC could a 7985/Viewstation call each other?

Re: IPVC and Cisco (Tandberg) CP-7985?

The 7985 is a Skinny (SCCP) device, like any other Skinny IP Phone. If you want to use the 'Confrn' and 'MeetMe' keys to create ad-hoc conferences, then the MCU needs SCCP ports registered to CallManager, and the MCU needs to be specified as the first device in the 7985's MRGL (the same is true for IP Phones with VTA attached). However, a SCCP-only MCU will allow SCCP endpoints to dial out to and add H.323 endpoints to conferences, but H.323 endpoints will not be able to initiate conferences (they don't have the softkeys).

You may wish to consider using an H.323 MCU, but all endpoints (SCCP and H.323) will have to dial Conference numbers to join conferences. The IP/VC 3544 MCU allows individual ports to be assigned for use by either SCCP or H.323 (rather than having an all-SCCP or an all-H.323 MCU).

H.323 endpoints can be added as devices in CallManager directly (and assigned a DN), or they can be registered to a Gatekeeper (which can be useful for DHCP-addressed clients), and then an H.225 intercluster trunk (and appropriate route pattern) is configured between the CallManager cluster and the Gatekeeper.

There is more information in the Voice and Video SRND for CallManager:

I can see you are as Cisco centric as myself.

I found out we have Tandberg endpoints and a Tandberg MCU (not Polycom) which can emulate a SCCP device via this Plug-In for CallManager from Tandberg, allowing the 7985 to dial a Tandberg endpoint transparently. I have to admit Tandberg was pretty smart with this, makes it a lot easier than IPVC!
