OsmoMSC tells the MGCP-GW which port to assign for voice calls. For that purpose, we have a very lean mgcpgw_client.c implementation.
This implementation utterly lacks proper cleanup: it simply increments the transaction ID used to assign a port number to new voice calls.
Practically, at some point all ports have been used once and the entire system will break down.

Implement proper cleanup and management of the transaction IDs, so that the MGCP-GW re-uses ports.
Possibly discuss this first.
