Tandberg E20 and CUCM 8.6.1

[pdinapoli]

followed several people's posts about how they've successfully registered an E20 to Call Manager.

So far no luck. I’m getting a Reason: 485 Ambiguous – device type not recognized.

I’ve also tried to reset to factory default with the ** (presentation key) ## sequence, the device reboots, but all previous saved settings are still present – so device is not going back to factory default (would like to try the initial setup wizard, but saved settings won’t blow away)

anyone have the definitive word on how to register a device?

Hi Paul,

It's always helpful to know what versions the systems are running in order to provide suggestions.  What is the exact version of software the E20 and CUCM (8.6.1......) are running?

I was able to successfully factory reset my lab E20 running TE4.0.0 with the * * (press the presentation key) # # sequence so I am not sure why yours is just rebooting.  Try the command: xcommand SystemUnit Configuration ResetToFactoryDefaults Settings: All and verify that it resets to factory defaults.

Also, ensure you have have everything configured per the admin guide:

and release notes:

Try again with the factory reset and verifying the CUCM config and versions and see if that corrects the issue.

Thanks!
