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.

Hi Kevin,
Do you have transcoding turned on? You may require this but in most cases is not essential.
Is the diverted call going back out over SIP or through a form of PSTN/PRI connection?
Cheers,
David Trad.

Hi David
Yes. Transcoding is turned on. Required for CUE at here.
Diverted call going back out over same SIP trunk.
But when I checked SIP trace.
Inbound call was using G711alaw. But outbound is using G729
Outbound dial-peers are configured with a codec class. (g711alaw. g711ulaw and g729)
Not sure how to correct this.

Bind SIP to interface is configured where?
Which device is performing NAT?
Also seeing the trace would help.

Kevin,
This is like a codec issue, you can configure voice class codec under voice service voip.
voice class codec 1
codec preference 1 g711ulaw
codec preference 2 g729r8
video codec h264
