Thanks for you answers guys, I test the parameters you suggested but still no audio due to the lack of reINVITE.  By the way I'm using 1.0.4 but I also tried 1.0.5pre3. One particular condition is that there is no on-hold before the Blind Transfer. Regards, Humberto

  <param name="media-option" value="resume-media-on-hold"/>   <param name="media-option" value="bypass-media-after-att-xfer"/>

...

My scenario is as follows:

inbound-bypass-media is set in the profile because we dont want FS handling the media.

1. A calls B 2. FS sends to B the A's SDP 3. B answers 4. FS sends to A the B's SDP 5. Media going directly between A and B 6. B REFERs the call to C (blind transfer with no reINVITE for Hold) 7. FS accepts(202) the REFER and sends the NOTIFY 7a. B and FS send the BYE 8. FS sends an INVITE  to C with A's SDP 9. C answers 10. FS doesn't send a reINVITE to A to let it know about C's SDP

Is that the expected FS behavior or is this a bug?
