What exact changes are done in MGCP after NAT

Hi All,

I am not able to understand the changes in the MGCP packet after NAT. The screenshot is of working and non working case. Office is working fine with port change after NAT. But at home the NAT does not change the src port. It RSIP packet from the phone to the MG.

What exact changes are done to a MGCP packet after NAT.

NAT should not be used with VoIP.

However, you may have better luck with H.323, or SIP, under NAT.
