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

[Eric Knudson]

Ah - so, data(modem) on the first 13, and voice(voip) on the last 11?
If using an nm-ct1, no 'voice-port x/x:x' will be created, so, you'll
need the vwic for that. Unless you're using an Access-Server, I don't
see how you can service both voip and data(modem) calls on the same
T1.

Regards,

Eric
