911 addresses randomly removed, disabling outbound calling.

I had an issue where the e911 address was there but I had to go in and accept it again. Seems to be a known issue with the RC database. JIRA: RLZ-32162 

I use the softphone desktop app and I see this when I switch workstations.

For me, the reason it happens is because I have not logged into the Admin portal and deauthorized the previous workstation before attempting to login on the current workstation.

There has to be a reason for this, likely security, but it's frustrating having to do all of this daily, some times more than once:

Bring up Rincentral.com
Load the login page
click on Sign in to bring up the profile login window
Choose my profile
Let the account page load
click "settings"
THEN phones & numbers
THEN phones 
THEN edit
THEN 'Deauthorize this computer"

I'd like to see a simple "would you like to deauthorize (whatever) computer" as an option when signing into a new workstation. But I'm probably in the minority as I work in an environment where we do not have assigned seats, so....

Yes, several times.  I thought it was the new meds.  Thanks for saving me a trip to the doctor!
