Seems like a network problem. Can you have your network admins install a packet sniffer and see what's breaking the tcp links?

Completely agree, maybe the NIC is bad, maybe the 2 servers are on WAN and WAN has disconnections or even on LAN too much broadcast/traffic and makes the link go down, what is sure is that this should be seen on both, TServer and PBX, sides.
