<p class=MsoNormal>Hi Joel, I had a similar issue. I would see our
calls drop after exactly 30 seconds. It turned out to be an issue with
our carrier TimeWarner telecom and thier Oakland SIP switch. We
repointed to thier North Carolina SIP switch and everything cleared
up. TW is running Sonus switches.<o:p></o:p></p>

<p class=MsoNormal>I have a customer that is experiencing a weird issue.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>Currently some of their forwarded calls are failing after 29
secs. I believe it is only happening when the calls are forwarded to 2 specific
carriers, but cant confirm that yet.<o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>I have a ticket open with the carrier so that they can take
a look at the traces we have captured. <o:p></o:p></p>
</div>
<div>
<p class=MsoNormal>The issue happens the following way. Inbound call to main
company DID goes to an AA, if no choice is used by the caller then it goes to a
live person. However afterhours this live person forwards their call to an
offsite #. When that offsite # receives the forwarded call they are only able
to stay on for 29 secs then the call dies on both ends.<o:p></o:p></p>
