CME inbound SIP call forwarded or diverted has no audio in either direction

sometime911
Level 1
Level 1

Inbound and outbound calls are working fine.

Inbound calls answered by agents then transfered to external numbers working fine.

But Inbound calls were forwarded or diverted directly (Call forward) by CME to external numbers have no audio.

Signalling works fine. (External number can answer can hand up. But NO AUDIO)

Did some research on web and found this post.

But No NAT and FIREWALL are involved in this case. also check configuration

These two command has already been added by CCA.
