Facing "The device associated with that extension or dial number is invalid" while using DX80 telepresense phones

[Sasikumar Divvela]

Hi Team,

We have EX and DX series telepresence as agent end points. But DX series phones are facing issue "The device associated with that extension or dial number is invalid" while logging in agent. EX is working fine. Both phones are properly registered in CUCM.

Can some one please help me here to resolve the issue.

Thanks in advance,

Sasikumar.
