Thank you for your reply. Unfortunately I send all pstn traffic to a single
gateway provider. So what I really need is for ser to check if this user is
in the 36countries group, and it dialled a number outside of the 36
countries then denied. I was thinking of using multiple if URI but i don't
want to define a lot IF statements. Hope someone here can share something
that they were able to do.

you have two servers

calls to only 36 countries:

the URI to the 36 countries in question which really
isn't THAT bad, but
dependent on their numeric format for numbers, it could get annoying to
specify each one (especially if they have differing formats for land line
and mobile numbers). It's not undoable, though.

Currently, when I see that
