Hi MrTom!

I am having the EXACT SAME ISSUE! Poly referred me back to RingCentral and RingCentral(Spectrum Business) refers me back to Poly. It is maddening! The one thing both have said is not to try and do a factory reset on the phone and then reprovision. They didn’t explain why, but it’s the only solid advice I’ve gotten so far! I have the Edge E220 and I’m wondering whether these can be “admin phones” at all or whether they’re primarily just expansion phones without the memory or technical capabilities of the more complicated phones. 

I am reading that there is a way to set the password using the configuration file, but I’m not nearly brave enough to try that for myself! Good luck!

I know it’s not the same as the Edge, but RC sets the Admin for our Polycoms from factory 456  to  789  

Try that - see if that helps.

You can factory default them without the password.

1. Power up the phone and the Handsfree and Headset buttons should illuminate (This may depend on the Edge E model)
   
                

   
   and once they turn off press the 1, 5 and 3 Key at the same time until the below screen appears:
   
   
   

2. Now either enter the known phone password or the MAC address of the phone in lower case.

3. Press Ok after entering the MAC address. The phone will reboot 3 or 4 times over the next 5-10 minutes. Do not press any keys during this time. 

4. If the phone is not automatically provisioned, you may be asked to change the admin password on the phone.  After this, you are ready to continue setting up your phone!

It’s that last part that needs clarification, “you may be asked to change the admin password”.

So would that be the default admin password, or the remnant admin password that’s not known?

Then, if it’s provisioned, there wouldn’t be any need to “continue setting up your phone” because it should be back to exactly how it was before the reset, but with a new admin password?

The edge series need manual config prior to them getting an auto provisioning when they are factory defaulted, its a pain!
It will ask to accept a EULA then set a timezone and then an admin password. You will then be able to access the web admin portal with the password you set
If you simply want the admin password (which is likely easier) have you logged a ticket?

You can set the password to essentially anything and then login with that password and manually input the provisioning link or if using DHCP option 66

Once the device reprovisions it will have the admin password set by ring central. Unless you use it as a 3rd party in which case you would be required to manually configure the phone entirely. 

So what would that admin password set by Ring Central be after reprovisioning? I don’t want to end up at the beginning after doing all that work. I need the admin password so I can change the VLAN settings in the phone, the reason for resetting it in the first place so I can modify administrator settings.

Ask them to provide the admin password for the device (so long as your provisioning using the MAC) they may give it to you! - Check Private message
