[cisco-voip] Calls from Analog ATA186's dropping out after 20-30 minutes

[Jason Burns]

Is there any firewall between the ATA and the CallManager, or between the
ATA and the other IP endpoint of the call?

You might need to SPAN the switch port the ATA is plugged into and get a
packet capture to see if the RTP stream really is healthy the entire length
of the call.
