directly between the end phone (Polycom here) and the Level 3 media gateway
that transitions the call to the PSTN.&nbsp; I&#8217;d recommend you take a capture on
your furthest point out towards Level 3 (outside of BroadWorks) and also have
the conference provider take a capture on their end as the call comes in.&nbsp; Then
you go to Level 3 with the proof that something bad is happening within their
network or after they pass off to the PSTN, and they can either fix the issue

<p class=MsoNormal>Have you engaged L3 yet on this issue? If not get them on
the phone, armed with your own captures showing appropriate RFC2833 event
duration and if you yell loud enough they'll setup the instrumentation on their
network to trap it. My guess, L3 isn't terming the call themselves and at some
point the converting RFC2833 to inband to hand off to the eventual term
carrier, and that carrier is accepting the call via a Sonus which is mucking it
