Cannot Call Teams Number

[Trevor_Howard]

We assigned a number to a teams user, that user can call out but when calling it from an external number it will go to voicemail.

@Trevor_Howard  I had this same issue recently and was able to resolve it by going into the Teams Admin Portal, and changing the user(s) Coexistence mode to "Teams Only"

Yes, Thank you! This solution worked for me too.
