[asterisk-users] Strange ISDN-problem with incoming calls out of the same city

[Marco Mouta]

Does this number (you are dialing) has been ported from a different Telco?

 When you dial from the other city and you get "service not available" you
may be dialing from a different Telco that either has no route aggreement
for the dialed network, or the number portability database (of Out of city
Operator) is not up to date.

Can you confirm this two things?
