[cisco-voip] Phones losing connection to the CallManager

[Gheorghe PLETEA]

Is MPLS, 200 Mbps, never seen more than 50% used.
The problem is I have multiple messages "CM-aborted-TCP" that means CCM
closed the TCP session, and I don't understand why.

Thanks,
George

What's the connection like between the phones and the CM(s)? Local LAN?
Frame Relay? T1? MPLS? Firewall(s) in between?
