Microphone control issue in Android SDK

When an Android user is on an REM call, and a normal voice call comes in to the device, both audio streams are audible on the calls. Is there a way to provide more granular mic control?

Could the app listen for standard Android telephony events, and put the RE Mobile call on hold when a regular phone call is answered?  The call could be resumed after the phone call ends...

Thanks, David. Seems reasonable enough. I could see some issues around triggering that hold event without prompting the user first, but it may be worth exploring. Maybe if there's a trigger to put the REM call on hold when the voice call is "answered", rather than "ringing" it could provide the user the ability to notify the REM far end agent that they were about to be put on hold. I'll see if we can explore that idea further.
