[OpenSIPS-Users] registrar lookup() and avp_aor

[Darren Sessions]

Excellent advice Bogdan! (and sorry about not starting the new thread)

Basically I had a vendor sending 'rn=' number portability tags (see  
RFC4694) in the RURI of the invite. We tracked in the registrar module  
source code (which led us to the parser functions in the core code),  
and while we've been able to see other supported tags in the RURI,  
'rn=' isn't one of them that we could find.

I was able to implement a solution using the aor_avp modparam in the  
registrar module though just as you suggested, and then using  
avp_subst with some regular expression to strip out what I needed gone.

I did a detailed write-up on my website, but basically it goes  
something like this:

---

modparam("registrar", "aor_avp", "$avp(i:1402)")
--snip--
if (!is_avp_set("$avp(i:1402)")) {
   $avp(i:1402) = $ru;
   xlog("L_INFO", "[R14] Setting ruri_user_avp = $avp(i:1402)\n");
}
avp_subst("$avp(i:1402)", "/;rn=[0-9][0-9][0-9][0-9][0-9][0-9][0-9] 
[0-9][0-9][0-9]//");

lookup("location");

Thanks again!
