Hi!
1) How long does the outdial take? Does the Dial-Command return immediatly?
2) Maybe dial-out is blocked by your carrier? Did you try to open a
trouble ticket there?
3) What number do you try to call? Did you try some different number?
Alway the same problem?
You receive ISDN-Cause-Code 18. Not sure though, but I would open a
troubke ticket at your carrier.
