 Hi jehan, who are the chief developper of the blackberry project, the device can support simultaneous play/record, the problem is originated on the packet info at a secuential send of packets, the receiverstream "receive" just "AMR"
Can you elaborate ? what do you mean by "receive" just AMR
  header and stop the audio, but client still sends audio packets....
From the trace you send me, the error comes from the send stream which is stopped by the BB with error Device unavailable.
I was try to determine when the header is send but is appear to be random issue...
My question to the chief developper is "why you do not observe that AMR header who stops the audio on the other client?"

Well, I'm not really optimistic. The following trace means the BB has stopped the record stream just after the play stream begin:
SendStream-Warn:Got event deviceUnavailable[]

From my experience, having this sequence of event means the device does not support simultaneous play/record.

We download linphone blackberry version to BB Bold series and we are
able to REGISTER and place calls.

The issue is other party is not able to hear our Voice.  When we ran
the latest source in emulator and look at the debug messages, we are
getting device unavailable error.

Please see debug messages.
