How about:

      ....
      &blacklist(${exten});
      ....

macro blacklist(the_exten)
{
    switch(the_exten)
    {
    pattern +4390[01]: Hangup();
    default: return;
    }
}

You could use something like the above.

Basically, you are using the pattern matching capability to
end the call for certain extensions... so the above should
come close. If you really, really want to keep your gosub call,
then you can, you'll just have to ignore the warnings, iirc.
