In this post I like to notify you about the upcoming support of Music On Hold (MoH) with Microsoft Teams. As of now MoH is planned to be released in June 2019. MoH will provide music to a caller as long as he/she is on hold by the callee, instead of silence.
Conclusion, opinion and summary
MoH is a basic telephony feature in my opinion. If there is no music you might think that the line is dead and you hang up after waiting for a while.
Well, please note, if someone would just mute his/her mic and let you wait in the line there is no MoH.
