You can easily check this in the SIP invite. I’m working mostly with Audiocodes so the screenshots below will be based on the Audiocodes Syslog tool.

Choosing the right Teams IPPhone Policy

2021-02-04 2 min read Microsoft Teams     "Erwin Bierens"

In this article i want to show the different capabilities of the Microsoft Teams IPPhone Policy. Do not get confused with the SfB IPPhone Policy, this one only controls the global policy and it’s not possible to create your own.

The Microsoft Teams cmdlet Set-CsTeamsIPPhonePolicy is only available in PowerShell. When logging in to your Tenant you can check which cmdlets are available.

Get-Command -Module tmp_3ju02ihp.npo | Where-Object {$_.Name -like "*TeamsIPPhone*"}

Use the temp module name in above cmdlet.
