Toll-free dialing via PRI problem</span></font><o:p></o:p></p>

<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>We have a PRI from Telepacific. Asterisk 1.2 and a Sangoma A101
T1 card.<br>
<br>
Outgoing calls to certain toll-fee (8XX) numbers fail -- we hear ringing but
the calls are never answered. All other calls, and most toll-free numbers
are not affected. The numbers that are affected are all travel related
companies (United Airlines, American Airlines, US Air, Starwood Hotels, etc.)
we cannot connect to any of these numbers. <br>
<br>
Telepacific has been very helpful, but based on their diagnostics have
determined that it's a configuration problem on the Asterisk box and not a
problem in their network. They brought a test set to our office,
connected to the PRI and successfully dialed the numbers we cannot reach. <br>
<br>
Based on watching the traffic go by they told us that we were sending
"Progress Indicator length = 2" and the that was incorrect, we should
remove the Progress Indicator. I have done a bunch of Google searches and
searches through the voip-info wiki and the digium lists and am not finding
anything about removing the "Progress Indicator". I have also
asked the Sangoma Tech Support folks and they had a couple of suggestions but
nothing has worked. <br>
<br>
I hope someone has a bit more insight -- it's rather annoying that we can't
make airline or hotel reservations from the office.<br>
<br>
Thanks,<br>
<br>
