[OpenSIPS-Users] Join AVPs?

[Vlad Paiu]

Hello,

The avp_pushto function is kind of limited in functionality, since the 
1st param ( the destination ) can only be one of the following
/destination = '$ru' ['/'('username'|'domain')] | '$du' | '$br'


/The script gives you more flexibility. You can do something like :
         $var(i) = 0;
         $avp(result) = "";
         while ($(avp(uuri)[$var(i)]) != NULL) {
                 $avp(result) = $avp(result) + $(avp(uuri)[$var(i)]) + ",";
                 $var(i) = $var(i) + 1;
         }


The $avp(result) will now contain all the values of $avp(test), 
sepparated by commas.
Then, in order to add that info to a Header in the reply, you can call :
     append_to_reply("P-Associated-URI: $avp(result) \r\n");

Best Regards,
Vlad
