Can't login to ATA192 Phone Adapter Configuration Utility

[kevin-mitchell]

I have configured several Cisco ATA192s using Webex and have an issue with remote access.  Onsite I have configured all the necessary settings to allow remote access.  In order to do so, the utility makes you change the device "admin" login.  After doing so, I can no longer access the device with the "admin" password.  The "cisco" user level login works just fine, but you can't complete any admin level changes with this login.  I have tried logging into multiple devices with my new login credentials, and "admin" will not work.  I receive "Invalid Username or Password. Please Try Again.  After several attempts, I get a temporary lockout from the units.

I had luck with changing the admin name itself to something other than admin. That works until it connects to Webex. OP sent a message showing a TAC case he had started. Summary was that Cisco does not want to allow editing once it's connected to Webex. I was able to log into the device with the user level account while connected to Webex. My current issue with that ATA is that it goes offline and will not come back up until its power cycled. Some cases a factory reset is required. Then you wait for it to go down, rinse, and repeat. We've had a few in use for over a year with no issues up until the last 2 months.
