Hi, I've found that Linksys SPA9000 (some sort of IP PBX) signals extensions in a "ref" parameter of From-Header, like: From: <sip:line1@matrix.sipura.com>;tag=1234;ref=105 Is there a way to easily access this parameter? Seems like... $var(ext) = $(fu{uri.param,ref}); ... doesn't catch it because it's not part of $fu. Any other ways except trying to assign $hdr(From) to an AVP and extract it using avp_subst(...)?
