[cisco-voip] Phones losing connection to the CallManager

[Gheorghe PLETEA]

Hi,
I have a problem with some phones losing the connection to the Cisco
CallManager (CCM).
A similar problem was posted, few months ago, by Matt Oliver, as "Phones
displaying CM Down during calls".

I noticed in the ccm traces many messages that mentioned last reason of
restart as "CM-abort-TCP" (100 messages in 3 days, for 1000 phones).
Can anyone tell me what can be the root causes for these? 

Thanks,
George
