I have a CME version 4.1(0) on 2821 router with IOS 12.4(15)T5.
i configured the following dial-peer:
dial-peer voice 15 pots
and when i try to call 8320 i get a fast busy tone
i tried csim start command with debug voice ccapi inout and get the messages shown in the attachment.
Note: the service aa command under the dial peer is used for auto attendant purpose.
could any one please help me to know the reason of this?
