Greetings, are running CM 4.2(3) this was just upgraded from 4.1(3) and we saw the same thing on both versions. We are sure it is a config issue, but have not found it yet.
2 sites BH and DT. Both sites have 3800 GWs, and are running MGCP. Sites are connected via 100MB gigaman link. The CM's are at the DT site. G.711 is the only codec configured for both regions. They do not want MoH, therefore per Cisco TAC the MoH servers were removed from MRG.
Calls coming in via PSTN to BH site are put on hold, and get disconnected after 60 seconds.
