I have an issue where IP phones register to my SRST reeference even though the WAN is Up and there are no issues. I see from the trace the following: Last=CM-closed-TCP.....Can anyone tell me what this means? Has anyone come across this and fixed it...
you help is greatly appreciated... full output seen below:
I'm also seeing TCPPID socket broken errors roughly at the same time...any clues ????

What this means that TCP connection between the IP Phone and the CUCM is getting reset/broken causing the phone to think that CUCM is unavailable and it registers with local SRST.
In CUCM, please view the event viewer application logs through RTMT and you should see either device unregistered or device transient connections messages for the MAC of one of the phone you are experiencing this problem with.
For that message, you should have a reason code. Can you tell me what is the reason code?
Most likely, CUCM is closing the TCP connectsion because it is not receiving keep alives from the IP Phone causing it to think the phone/network is down and so it resets it.
