Microsoft Teams users will get the Call Merge feature next month. This upcoming Call Merge feature will allow Microsoft users to merge their active unheld 1-1 call into another 1-1 call or another group call. This feature will work with both Microsoft Teams VOIP calls and PSTN calls.
On a related note, Microsoft recently announced the roll-out of Microsoft Teams and Skype interoperability.
- Teams users can search for and start a one-on-one text-only conversation or an audio/video call with a Skype user.
- Skype users can search for and start a one-on-one text-only conversation or an audio/video call with a Teams user.
This Teams and Skype interoperability feature is now available on the desktop, web, and mobile for both Teams and Skype.
