Mohammad –
How did FXO ground start function on the Carrier Access channel bank using analog lines?
Does using ground start (which is often associated with battery reversal) provide answer supervision?
I am running IOS 12.2.7b Enterprise VOIP/VOATM with IPSec56 on a MC3810.
My MC3810 was successfully operated using standard loop start setting as specified in Carrier Access manual.
Answer supervision is not there locally.
