Hi,
I have a client with 2 7100 MP10a, at version 4.60b. Call from site A to B is working fine. But from B to A, B ear the A fine, but A can not ear B. The port that need to be open are open... Does somebody have resolved a similar problem?

Do you have ping enabled on both routers?

Have you opened both the 30,000 & 40,000 port ranges? If you have MPS on, one of the sites may be trying to route the call without using the MGI ports.

Make sure you've got the correct Public IP in 2.1.2 on each side.
