[cisco-voip] ISDN PRI: Service/Option not available, unspecified

[Nick Matthews]

First thing I would try is removing the 1, and just dialing 1800.

Then I would compare the ISDN message to an 866 or something similar and
see what you see for the plan/numbering:

        Called Party Number i = 0x80, '1800XXXXXXX'
                Plan:Unknown, Type:Unknown

You could try setting this to the same setting as they are accepting for a
normal LD call. Or just go through the list of permutations and see if any
work. Sometimes playing around on your own system is faster than waiting
for the service provider to tell you the problem.

It's also quite likely it's a carrier problem you can't do anything about.
I'd contact them and see if changing the dialed numbers or Plan/Type
changes the outcome.
