[swest]

I'm supposing the lack of response indicates it is not possible to do this?

I have so far tried the following without success:

Use of the static mute() method net.rim.device.api.system.Alert class. On closer inspection it would seem that this class has nothing to do with the microphone, but it was worth a shot.

Use of the Player and VolumeControl Interfaces. I am lead to believe that VolumeControl can manipulate the volume and mute settings of a Player. However, it seems to me that a Player does not have control over a call in progress (but I may be wrong), but to some output that has been pre-recorded. Maybe there is a constructor of Player (via the Manager class) that would allow me to hook into the current call? Other than this, I am pretty much running out of ideas.

Any pointers would be much appreciated.
