I am having troubles with a Cisco IP phone but in traces I see this message:
Outbound SCCP message to 220.127.116.11 at 08/18/2015 09:56:27.242
StationD: (0051062) Can't forward DeviceMediaPortCloseMsg to cdpc for CI 49018231; can't find it.
Source Filename: SDL002_100_001192.txt.gz
I tried to find what's the meaning of that message but I can't find anything.
This is a fragment of my call flow.
18.104.22.168 IP Phone
22.214.171.124 Voice GW
I hope you can help me.
The exact issue is that we see in CUCM traces a "500 internal Server Error" when some calls are assigned to that phone.
And in Gateway debugs we see the same error.
This is a Contact Center Enterprise we have all the SIP trunks between CUCM and CVPs and Gateways.
And not all the calls fail.
CUCM version is 9.1(2)
The extension is an extension mobility profile for 7942 SCCP.
Ths is the INVITE:
