Let me know if you see anything. I'm not able to see anything wrong.

 

Thanks,

I smell a NAT... is there any NAT involved?

	Okay. I just tried this.
	 
	 
	 
	Now we're getting the audio going one way, but not the other.
So, I
	    

can
  

	hear the person that I just transferred to, but they can't hear
me.
	 
	 
	 
	Anyone have any other ideas?

	try blocking ICMP packets TO the MSS.... i had this exact same
problem
	    

a few
  

	months ago.... MSS starts sending RTP to FS before FS is ready
to
	    

accept....
  

	so the OS catches the port not open and returns an ICMP 3:3 back
to
	    

the
  

	MSS.... which in turn chokes on the queued up RTP and refuses to
send
	anymore...

	We find that some equipment (in fact a lot of equipment) have
features
	 
	that cause issues to be quite non-obvious, so perhaps you could
give
	 
	the pcap to Brian for him to review. He's a total ace when it
comes to

	would be most helpful to capture a pcap of the entire thing by
itself
	 
	 
	 
	start
	 
	 
	 
	to finish.

	No. I realize that's it's a B2BUA and that's exactly what we
want.
	 
	 
	 
	 
	 
	 
	 
	Everything with the transfer seems to work fine, except that
there is
	 
	 
	 
	no
	 
	 
	 
	audio.
