MGCP after NAT

[ravindra Krishna]

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.

Any assistance will be highly appreciated.

Regards,

Ravi

Hi All,

We resolved the issue.

The dump was fine. The issue was with the router ahead which was running in half-bridge. We converted to NAT and it MGCP worked fine and the phone was working fine.
