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

 

Thanks,

John

        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

        No. I realize that's it's a B2BUA and that's exactly what we

        Everything with the transfer seems to work fine, except that
there is
