[cisco-voip] Question: Splitting T1 with PRI service (moot)

[Tony Kava]

Eric:

I was probably not clear on that posting.  I meant that the T1 would be on
the NM-CT1, not the VWIC.  I'm probably going to have our phone company
setup a PRI group for the last 13 channels and standard DS0s for the first
11 channels.

Thanks.
