In the face of "the device associated with this extension or the dial number is not valid" when you use DX80 telepresense phones

Hi team,

We have EX and DX series telepresence as endpoints agent. But DX series phones are facing issue "the device associated with this extension or the dial number is not valid" when checking in the agent. EX works very well. Both phones are properly recorded in CUCM.

Can you please help me out here to solve the problem.

Thanks in advance,

Sisi.

In my case, we tried to do a few different modifications here and there on the DX650 but never managed to do work.  Randomly, I was able to connect to the fineness with the DX650 as my camera, then my colleague could not connect to the Finesse with his 9971 as his camera - (keep in mind this was in an environment of model and it was just her and me as agents).  Since I saw this strange behavior and doesn't do not sense, we rebooted the server CCX. Once she is back to the top, we were also well able to connect successfully and had not had the problem since.

Thank you

EK
