[asterisk-r2] Some long distance numbers get congestion message every time

Wed Dec 3 10:49:42 CST 2008

I have installed libopenr2 1.0.0 on Asterisk 1.4.22. I have some long distance numbers (national and international) that get the "all circuits are busy now" message every time. We know the numbers work because we've tried them from other lines. There is no restriction for such numbers so we are kind of lost here. This is the first DAHDI installation we made but we have several Asterisk 1.4.21.2 with the same system configuration (computer, Sangoma card, etc.) that do not present that issue.

Here is my system configuration:

Asterisk running version 1.4.22

Asterisk source version 1.4.21.2

CentOS 5.2

OpenR2 version: 1.0.0, revision:exported  ->got from mfcr2 show version
