Voice Gateway PRI question

Answered Question
Dec 18th, 2009


I am going to migrate a remote office's old PBX system to our centralized CCM with Callmanager V5.12.  My questions is the office has a PRI with 16 channels.  Do I set up the voice PRI on the gateway the same way as if it has 24 channels?

controller T1 0/3/0
framing esf
linecode b8zs
cablelength long 0db
pri-group timeslots 1-24 service mgcp

if not, should I change the pri-group command to 17 channels(including the D Channels)?

pri-group timeslots 1-17 service mgcp

Any help would be appreciated.

Thanks in advance

Yes, but drop the service MGCP.

We do NOT support fractional PRIs with MGCP, if you want to use it you'll need H323
