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

 

Thanks,

John

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...

I have a pcap, but I'm not able to see anything obviously wrong with
 
 
 
it.
 
 
 
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
 
bug hunting.

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.
