Title: Fwd: Re: OpenSER ENUM module now has ISN functionality

Good news!   Looks like openSER might have native ISN lookups in it shortly.  If anyone is interested in this patch, please try it out and let me know.  I don't run openSER in a non-production environment right now, so I don't have a handy testbed.

John,

I don't think Juha has updated the README / docs yet. However, this is what he sent me:

enclosed find a modified openser cvs HEAD enum module that includes
isn_query(suffix) and isn_query(suffix, service) functions.  README has
not been updated yet.

here is usage example:

   if (uri =~ "sip:[0-9]+\*[0-9]+@") {
             isn_query("test.fi");
   }

you can replace "test.fi" with "freenum.org".

this test version of isn_query produces some extra debugs so that you
see in syslog what happens. for example, call to sip:1234*
produces:

May  9 12:59:50 rautu /usr/sbin/openser[9111]: isn_query(): Name is 4.3.2.1.260.test.fi.
May  9 12:59:50 rautu /usr/sbin/openser[9111]: isn_query(): resulted in replacement: 'sip:'

when dns has in test.fi zone entry:

*.260     IN      NAPTR   1 1 "u" "E2U+sip" "!^\\+*([^\\*]*)!sip:\\!i" .
