Hi Syed,

Can you collect them together for a sample call.

Can you confirm the call flow?

From the logs i see below

Can you try shut/ no shut of voice-port, If that don't help collect below logs

show voice dsp group all
show voice port summary
show runn
show version
show trunk group

 Enable Voice IEC syslog 

enable  
configure terminal  
voice iec syslog 

collect below logs for another sample call
debug voip ccapi inout
debug vpm signal
debug voip ccapi error
debug voip vtsp all
debug tgrm

Mohammed I really appreciate your support.

I bounced the voice port with shut & no shut commands and it started working.

May I know what went wrong with this, please?

[Mohammed Khan]

seems like voice-port was in abnormal state.

[Syed]

Since the port was administratively & operationally up, hence I did not think of it.

Now it changed to admin (UP) Oper (Dorm).

Wasn't that good status to go with?

[Syed]

Please find it.
