[OpenSER-Users] CPL and $var issue when different process

Hi, maybe someone could confirm this:

At the begining of my script I set a variable:

$var(gateway) = "123.123.123.123";

Later, I run CPL for calls to internal users and there could be forwardings and so. I set CPL "recurse" parameter so convert 302 from UAS into a new branch into CPL.

At the end of CPL I run "route[20]" in which I use the variable $var(gateway), but sometimes it appears empty. I think this could occur because CPL can involve various OpenSer process. I think that when CPL receives a 302, maybe sometimes it's a new OpenSer process and since it's a reply the variable at the begining of my script is not read, so it appears empty. Am I right?

A solution is to use AVP instead od variables since AVP's remains along al lthe transaction. Am I right?

Thanks for any confirmation. Best regards.
