Cannot Login to Teams and Busy Signal

Hello - I've been working on a major problem with my Polycom vvx 411 and 450 office phones. We recently moved our phone system over from Zoom to Microsoft. Everything was moved over fine, and we can use our mobile phones and desktop to call our main office number where we get our Auto Attendant greeting. But I noticed our Polycom phones are not ringing or responding to incoming/outgoing calls. When I dial our main number in the Polycom, it gives me a busy signal. I tried to log in to Teams from the phone with the code that was given, but each time I tried, nothing happened. The display remains on its login screen. 

I put in a support request ticket over four days ago, and still have NOT heard back from anyone in Polycom support. I really need help with this issue right away because my employees cannot use the Polycom to dial out and receive incoming calls, and they can't login to Teams on the polycom phones. 

The firmware version is

It's been factory reset several times

My Polycom Case Number is 34339652 

My email is Isadore@digitalfacemedia.com


Again, I need help right away. Please have someone contact me. This is hurting my business.
