I have a problem with call dropped after 5 min ( during mute "on" ). If mute is "on" RTP packets will not flow from Lync server. Do you know how to force Lync to sent "empty" RTP packets during mute in enabled ?
PS. Current fix its not working :
Set-CsTrunkConfiguration -EnableSessionTimer $True Set-CsTrunkConfiguration -RTCPActiveCalls $false -RTCPCallsOnHold $false
