Calling in Teams is powered by Phone System (formerly known as Cloud PBX), the same service in Office 365 that enables PSTN calling capabilities in Skype for Business Online.

The Phone System feature set for Skype for Business is different from the Phone System feature set for Teams.Also With Direct Connect we can use our existing  PSTN Telephony system through an SBC . To connect the on premise SBC to Microsoft Teams a sip proxy is used to connect to  sip.pstnhub.microsoft.com.

Microsoft Teams have a new feature consult before transfer.

By using this option we can help the  wrong callers calling our extension to reach the right person.

This feature lets you quickly check in with another person via chat or audio call before transferring a call to them

Anyone with an Enterprise Voice license can do this, not just delegates! To try it, when you’re in a call, click More options (…) > Consult then transfer.

Prerequisites:

1. This works from the Teams desktop app from Windows 10 PC.
2. Need to have the remote assist app installed on the holo lens.
