Trying to start a call with a user on teams from a web page. All I have is their email.
I was trying to copy the example here: https://learn.microsoft.com/en-us/microsoftteams/platform/concepts/build-and-test/deep-links#generate-a-deep-link-to-a-call
They say to use this format to start a call: https://teams.microsoft.com/l/call/0/0?users=EMAIL_HERE
It starts a call with joe@contoso fine but when I try and use any other email it fails with this message:
Any help would be appreciated.

You need to specify either a upn or a phone number with a 4: prefix as specified in the documentation https://learn.microsoft.com/en-us/microsoftteams/platform/concepts/build-and-test/deep-links#deep-linking-to-an-audio-or-audio-video-call
https://teams.microsoft.com/l/call/0/0?users=,4:<phonenumber
Note that the upn should be of the user as it exists in the callers AAD, so for guest users you'll need to lookup the guest users upn which will look something like upn#something#@contoso.com
