I've been trying out a few new termination providers, and am finding that
the first second of media is being lost.<br><br>I get early media
(ringing), then when the call is answered the first half a second to a
second is lost, then the rest of the call is fine.<br>
<br>The engineers at one of the providers ran a sip trace and a full packet trace, and it
looked like everything was being delivered from the pstn to my server.
They said that none of their other customers have reported this problem
before.<br>
<br>I've tested connecting to pstn's in several different countries,
with the same results. I've used a couple of other termination providers in the past (1
still in current use) which have been fine, but now have 2 that are losing the first part of the media.<br><br>So it seems like
it's specific to Freeswitch, with some subset of conditions for some providers.<br>
<br>This is running on Ubuntu on a Amazon AWS server, in case that helps.<br><br>
Any ideas how to narrow it down further?<br><br clear="all">Cheers,<br><font color="#888888">Fraser<br>
