Cannot sign in to a desk phone using Teams SIP Gateway
Hi all, I'm attempting to sign in to a Polycom CCX VVX 411 desk phone I have onboarded to the Teams SIP Gateway by following the instructions here. As far as I can tell, the device has been confi...
- Mar 31, 2022I finally got connected with a helpful Microsoft 365 support rep and it turns out the problem was that the "SIP devices can be used for calls" setting was not enabled on the Calling policy assigned to the user.
My fault, to be sure; that being said, it would be helpful if there were some kind of error message during the web sign in process if the setting is disabled rather than being told "You have successfully signed in". May my misfortune serve as a warning to others.

I bumped into this issue too recently. It was working months ago but unfortunately not now.
I've confirmed the SIP Calling was enabled on the call policy. So we may need to drill down further with Microsoft Support.

Andy_Chau I discovered this article the other day; perhaps you may find it useful:
Common issues when using SIP devices with Teams - Microsoft Teams | Microsoft Docs
- NicholasSellMay 27, 2022Copper ContributorI've been through that common issues doc, checked every setting I can think of on a Yealink T46S, but getting a similar issue. Sign-In screen is up, sign-in on web shows success, but the device never updates and remains offline in the Teams AC.
I am seeing network traffic on the designated ip/ports for a certified teams phone plugged in right next to this SIP phone, but no inbound traffic coming from the SIP gateway to the Yealink. I'm wondering if there is currently an issue with the provisioning service?

Great news then...
That step is indeed in the procedure https://docs.microsoft.com/en-us/microsoftteams/sip-gateway-configure#enable-sip-gateway-for-the-users-in-your-organization
I agree that a meaningful error message would be better
