Hi,
You *can* tell the recursive call to properly return the retcode.
Instead of "return(route(2))", enumerate all possible return codes
after the recursive call (inside route[2]) and call return with the
same retcode:
route[2] {
if(lookup("location")) return(2);
if(!uri =~ "^sip:[0-9]{6}[0-9]*@") return(3);
strip_tail(1);
route(2);
if (retcode==1) {
return(1);
} else if (retcode==2) {
return(2);
}
}
instead of all these if-else statements you can use the 'switch' statement.

It was designed for such cases.
However, return(statement) will be taken in consideration for further
enhancements of the configuration language.

Hope this helps.

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
