Hi Andy!

What is your goal? Do you want to strip the extension till you get the "kopfnummer" (sorry, I do not know the english term)?

Maybe a special lookup function might be useful which does some kind of longest match matching (like the SQl query in the LCR module).

I know other which solve this problem by using a private ENUM tree with wildcard NAPTRs for the extensions which point to the "main URI".

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
