Summary:                    "No audio" on incoming bluetooth call to voicemail,
call dropped
Description: 
I have "context=incoming-mobile" in mobile.conf for my bluetooth phone.  It
connects, and Asterisk indicates that "Usable" for voice = "Yes", "Type" =
"Phone".

The incoming-mobile context directs the call to voicemail:
 context incoming-mobile {
    _. => {
        VoiceMail(9999,b);
        Hangup();
    };
}


When I call the bluetooth phone, I hear the outgoing voicemail message
"...9999 is busy... leave message...beep", then the call is dropped.  The
logs contain:

channel.c:2992 in set_format: Set channel Mobile/SCP2500-f304 to write

---------------------------------------------------------------------- 
This error appears to be caused because of the way chan_mobile handles
audio data.  Currently chan_mobile only reads audio from the phone when it
writes audio to the phone.  I am working on a fix.
