Hello I have three remote sites that are very similar in configuration and layout. Each site has a gateway using MGCP and SRST with a VPN connection over the internet (T1 or DSL). Periodically 2 of my 3 sites are failing and this is the message that I get in the trace and event viewer:
Error: StationEventAlert - Station alert.
TCP ProcessID: 188.8.131.523
Device Text: 32: Name=SEP001930C8F22A Load= SCCP41.8-2-2SR3S : Invalid SCCP message! : Invali
App ID: Cisco CallManager
Cluster ID: StandAloneCluster
Node ID: 192.168.18.20
Explanation: Station device sent an alert to Cisco CallManager.
Recommended Action: Ensure that the configuration for identified device is proper..
The phones will reset soon after I receive this message. However, the gateway is fine and stays up.
TAC is stumped. Any ideas?
