    I want to stream media to multiple phones using RTPMRx and it works great but if a phone has the headset enabled it is not sent to the speaker.
     
    I thought about sending Key:Speaker but this starts an outgoing call. 
     

    Is there a way to handle this?
     
    Many Thanks,
    Roland
