Hi BenRooke , 

I am not a microsoft guy, I do not have information about the plans to fix this but I wrote article about this behavior which tries to explain reasons why. It is problem coming from current design of the onhold function and the luxury of having the ICE protocol handling the media negotiation.

      I am seeing the same issue across three separate instances of MS Direct Routing that I have tested.

      I don't yet know of a solution but keen to hear if anyone else gets one.

      In the mean time I will keep looking!

       

      Thanks

        As I was doing more tests since my last response I can give you another point of view on this issue probably. The delay is noticeable also for regular Teams calls between Teams users and not only for Direct Routing calls. I still believe the negotiation of the media and transfer of the call to another On-Hold music source generates some of the delay but not the whole time.

        On top of that I have observed different time of the delay on different PCs and I assume it was related to HW configuration of the PC.
