I do see audio being received, but I don't hear it on my softphone. I see
no TX at all. Interestingly, the guy on the pri I was calling said he could
hear me. The remote pri is an asterisk box, so i set a DID on it to go
straight to the echo test. While that system is playing demo-echo I see RX
on my end, but when the actual echo test starts i see nothing.
