[Asterisk-Users] Intel 536ep as a FXO?

[Ed Rubright]

Hmmm...that doesn't work in my area either.  I'm in the 509 area code, 448
exchange with Qwest and dialing 509-448-9996 gave me the no service
announcement.

Perhaps calling Qwest customer service and asking for the milliwat test
number for my local calling area?

I'm also in a Qwest area, but that number doesn't work here. All of the
techs that I have asked gave it to me with no problems. They are shy about
the automatic ANI number, however...
