I have also seen this on a 4.4 system.
Calls were not being processed and the caller heard dead air. When a call was researched, I found that sipXproxy was loading the NAT plugin for the call even though the call was outbound to the PSTN via an AudioCodes gateway. On this system, NAT traversal was enabled and the Address Type was set to STUN. Since the system was not supporting remote users, we disabled NAT Traversal and changed the Address Type to a public IP address. The problem has not reoccurred since the changes to the configuration of the system.

But it is not clear to me how it would cause a hang. Can you disable session-timers in the phones and see if that somehow lessens the occurence of this incident?

Obviously this is just a band-aid workaround until we can resolve this issue, since this means they incur approximately 3-4 minutes of service interruption every time this happens.
