Polycom VVX400 with Teams

Hello.   My account was on SfB on Prem. I was moved to Teams Only mode (Hybrid).   Is there any way I can still use my old Polycom VVX400?

    I got my problem figured out.  My problem was there was some old proxy config in my VVX .  After I cleared that out my VVX400 registered with no problems. Anson2400

LinusCansby So in Teams emergency routing policy I have setup 9911 for emergency:

 

Emergency dial mask - 9911

Emergency dial string - 1414566911

Dynamic emergency calling - On

 

I have network with subnets including my Polycom and Windows app IPs.

 

When I call 9911 from my Windows app - all works fine - call is marked as emergency and routed correctly throu my SBC.

 

When I call 911 from my Polycom I get nothing.

LinusCansby Looks like Teams doesn't setup my Polycom location correctly.

 

On Polycom I have:

And my Polycom IP is correct.

 

But on Teams log for my test call I see:

Connectivity_LocalSite 10.0.137.0:51576
Connectivity_LocalAddress 10.0.137.0:51576

    I finally removed number recognition from Polycom but Teams doesn't still work correctly with 911

    So when I dial 9911 from Polycon that call is translated in standard 4digit normalization rule instead of emergency routing policy.  And that happens when on Polycom is signed in standard Teams user. For that user on Windows app all works fine.

     

    Line 4094: 0818133046|so   |3|00|[CSoRegexDigitMapElement]: Checking 9911 against ^(\d{4})$

    Line 4095: 0818133046|so   |3|00|[CSoRegexDigitMapElement]: RegexMap ^(\d{4})$ Declared match 9911 -> +14145669911

     

    Basing on my emergency routing policy 9911 should be translated to 1414566911 and routed to SBC.
