Archived:Call muting disables routing to telephony uplink (Known Issue)
Telephony routing rules have changed in S60 3rd Edition, Feature Pack 2 devices. When a voice call is muted from the Phone application, all playback to telephony uplink is automatically disabled for all clients, including Music Player, Voice Recorder, and 3rd party applications.
This affects Audio Proxy Server (APS) and VoIP Audio Services (VAS) clients running on S60 3rd Edition, FP2 devices.
Currently no solution available for Nseries devices compatible with S60 3rd Edition, Feature Pack 2.
