Emergency Locations, Port Data, and physical phones
From my the last update from Microsoft, the next update will be in June should have fixes for the phones.
As for the MS Teams client itself, that should work assuming you have the correct information in Teams. I'd double check the values being sent in the LLDP packets to make sure you're using the right values for chassis ID and port ID. Some switches will send extra information (TLVs) so it's important to grab the right fields.
If you connect a computer with Win10 and the Teams client on, give it some time to verify the networks. Go to Settings > Calling and see what location is showing up. If you see a location, close the settings window, and hit ctrl+alt+shift+1. It'll dump a bunch of log files into your Downloads\ folder. If you look at the file named "MSTeams Diagnostics <datetime>.txt" and search for chassisId, you should see what the Teams client is sending to Microsoft. You could confirm this is what you have configured.
I'm working on this issue currently, Teams windows client pulls location and routes to local PSAP, but Yealink MP56 is still going out to the national ECC.
I've provided a link to Microsofts latest release for Teams phone software, which does call out LLDP for E911 Updates. Unfortunately after updating my phones it still does not seem to make a difference. I've set up everything up to switch chassis ID#s, did not do Port ID #s. But now i'm wondering if i need to go down that rabbit hole to make this actually work?
