[Asterisk-Users] Problem switching from external ISDN-2 to PBX ISDN-2

[Lars Dybdahl]

I have a system that works perfectly using zaphfc on an external
ISDN-2 connection. When I move this to a PBX-based ISDN-2 connection,
it still receives calls, but is unable to dial out.

In Denmark, we have no long distance calls, but only national calls
(8-digit numbers) or international calls (00 <countrycode> etc.).
Normally, incoming national calls would be reported as 8-digit
numbers, but when I connect my asterisk to the PBX, it is preceded by
three zeroes (00012345678 instead of 12345678). This seems to indicate
a problem, too, since you normally only dial one zero on a PBX to get
an outside line.

Any ideas?

Lars.
