Call Park is coming to Microsoft Teams, estimated this year
The description for this feature is: Call Park enables users to put a call on hold and then retrieve the call from the same phone or another phone. The parked call can also be transferred to a department or general area where there is a common area phone. While a call is on hold the original answering phone can stay free for other calls.
It’s currently showing as “In Development” with an estimated release date of Q4 2018 – so a little under 2 months as I write this.
This will be useful for lots of business scenarios with a general incoming line where calls are answered and then routed. The description mentions as well that parked calls can be transferred to a “department” with a common area phone.
