Unable to register Phone to Webex Calling

[Jason13]

Getting an error trying to register an 8841 to webex calling.  MPP firmware is updated to latest version 11.3xx

When entering activation code on phone - I get error - Invalid Configuration.  Contact administrator'

The log file from Control Hub is below - the pertinent part appears to be 'unable to reach upstream service'

Any ideas?

Wanted to drop by in case anyone else runs into this.

This was self-inflicted pain.  I had this phone that I used as a demo for another client and failed to delete it from their control hub.  After deleting the phone/MAC from that, I was able to register it.

That log file had me running in circles.

Hi,

Have you tried deleting the phone from control hub and re-adding it with new activation code?

Thank you for your reply.  Yes I have.  Multiple times.

I have deleted phone from control hub.
I have reset phones to factory default.
I reloaded firmware.
