[Asterisk-Users] Problems dialing out - possible settings changes

[Jeff Busch]

First, I apologize if this info has been covered, I tried doing a search
on Google and the wiki and found nothing, but I could be searching for
the wrong info.

Second, I am new to asterisk and linux.  My knowledge is Asterisk is
much better than linux, so excuse the ignorance in some areas.

Configuration:
Novell Linux Desktop
Asterisk 1.0.6
Intel CPU/MB
TDM12P digium card (I think that is it - 1FXO and 2FXS)

Problem:
My calls are infrequently successful.  I have the dialplan to dial
_8NXXNXXXXXX and ignorepat => 8
When I dial 8206391xxxx, which is my cell... (and any of another 5
numbers I tried)  About 1 out of 6 times it is dialed the connection is
made.  The rest of the time I receive "the number you have dialed is not
in service" from the phone company.

I look at the Asterisk CLI info and it is saying that it connected
g1/206391xxxx and the number is correct.

I am using a standard copper line here via Qwest.

Interesting thing, if I place this on an analog port off our Inter-Tel
phone system, it seems to be 100% successful on the dial-outs.

I have tried changing cords and even moved the server so it is plugged
directly into our phone patch panel where the qwest line is terminated.

Any ideas would be helpful.

Thanks!

Jeff
