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 up.


and yes been there done that.
