Hi,
Add the following under dial-peer pots:
progress_ind setup enable 3
progress_ind alert enable 8
progress_ind progress enable 8

No need to add the above config as you're using mgcp not h323. Anyway, is there a firewall involved in this setup at all? You could be dropping RTP packets (udp ports 16384-32xxx, sorry can't remember them off the top of my head). Either that or a routing issue. Can you Ping any of your ip phones from your voice gateway?

Connectivity is fine and no packet loss.

Try this:
mgcp behavior g729-variants static-pt
mgcp behavior dynamically-change-codec-pt disable
I think you may be hitting this issue:
hth,
