VVX300 and MS Teams auto sign out

We have Polycom VVX300 phones at our office which login to Teams using the Web Sign In method. Because our staff are now working from home due to Coronavirus, the phones are not getting used and some users going to the office are reporting that they are logged out of the phones and are prompted to login in order to use them. Is this logout due to a MS authentication token expiring?  Or a config setting on the phone itself?  Any help would be appreciated.

Re: VVX300 and MS Teams auto sign out

Hello @VVX300user ,


Welcome to the Poly Community.

Please let me correct you on the terminology used. The VVX cannot log into Teams. You are using Skype for Business online most likely. Only our new CCX 400, 500 and 600 phones >here< can be used with Teams natively.


There is no setting on the phone which would cause it to log out after a certain time of inactivity (other than a Guest Signing) so the issue must be on the Microsoft end with some expiry.


In order to help you to troubleshoot this we can offer the following FAQ article:

Resolution: Have a look => here <=


Please ensure as well that you post the currently used software version.


Volunteers can try and help you once you post some useful information for us but if you seek official support a service ticket is required.


In order to raise a support ticket, you need to work with your Poly reseller as they may need to do this for you.

End Customers are usually unable to open a ticket directly with Poly support. Available End User Poly services offerings are detailed here

If this is some sort of an Internet discounter providing your MAC address or your Poly devices serial will enable us to look up who would be able to support you. This may not be who you purchased the Poly device from.

If the unit is no longer within the warranty please be prepared to Pay Per Incident / PPI. This is all outlined in detail here

Please ensure to provide some feedback if this reply has helped you so other users can profit from your experience.

Best Regards
