Incoming UDP is not working for Natted IP

[chaman prakash]

Hi All,

I have Natted IP address from 192.168.X.X to X.X.X.X . when the call is going out over SIP Trunk, outgoing call is working fine. But for the incoming call . Its giving no way audio. 

Please help me to confirm if there is a way to allow incoming UDP traffic to allow over Natted IP

The NAT device would need to support application-later payload inspection to rewrite IP and port information within the packet.
