[cisco-voip] Gateway / Gatekeeper Dial Tone Qestions

[Alan Su]

Hi Ryan,

The connection between gateway and PBX is T1-CAS, I also have E&M connection
in another end. So in this situation, does the call from PBX conected phone
to local POTS number occupy 2 T1-CAS channels? Many many thanks for your
help.

Regards,
Alan
