Cross tenant calling in Microsoft Teams using user extension.

Copper Contributor

Hello all,

I have a situation where there are multi-tenants in a subscription and each tenant has 100 users. 

Organizations want to enable the teams to call using the user's extension. 

For example, user A in tenant-Apple has extension 3312 and User B in tenant-Orange has extension 4414. So Is it possible for this user A having ext 3312 to dial out User B having extension 4414 and vice versa?


If so, what all I need to configure?

Thank You!

No currently this functionality is not supported. The only option is using the federation calling using the name resolution only.
