Microsoft plans to release federation between Teams and Skype (for consumer) in January 2020. This federation is in great demand. On Teams User Voice more than 3000 people voted for this. Except the description on the road map no further details are on docs.microsoft.com as far as I could see. However, I’m sure that there will be more details available as soon as the feature hits preview or general availability.

Teams <-> Skype (for consumer) Federation
What is the upcoming release of the federation between Teams and Skype (for consumer) probably like? As far as we can read in the road map it says that it supports chat and voip calls. I’d assume that this will be similar to what we’ve seen and experienced in the federation between Teams and Skype for Business at the beginning, e.g.
- peer-to-peer (p2p) chat
- peer-to-peer (p2p) voice calls

Conclusion, opinion and summary
In my opinion this is a good start for federation between Teams and Skype. I’m looking forward to it. In the past, for many Skype for Business (Server/Online) implementations the option to communicate with Skype (for consumer) was an important argument for globally distributed organizations with the need to communicate with freelancers, small agencies etc. In my view this federation option is another step to increase adoption and communication.
