[Users] Recursive routes and retcode

[Andreas Granig]

Hi,

I'd like to recursively strip off digits from the tail of a username (a 
numeric number in fact) and do a lookup in usrloc until an aor is found 
or the number underruns a lower bound, like:

route[2] {
   if(lookup("location")) return(2);
   if(!uri =~ "^sip:[0-9]{6}[0-9]*@") return(3);
   strip_tail(1);
   route(2);
}

route[3] {
   # check if numeric, then:
   route(2);
   if(retcode==1) {...}
   else if(retcode==2) {...}
   else if(retcode == 3) {...}
   # ...
}

The thing is that it obviously doesn't work (retcode is 1 as soon as one 
recursion happens) because I can't tell the recursive call to properly 
return the retcode like "return(route(2))" or "return($?)" or something 
like that. Any other ideas except using flags or is that the only way to go?

Thanks,
Andy
