Re: [SR-Users] Add custom parameter to To: header, and then recover it

But what you could do is extract the existing From header value, remove the From header, and append your own parameters to it: $var(new_from) = $hdr(From) + ";yourparam=yourval"; remove_hf("From"); append_hf("From: $var(new_from)\r\n"); Now, as to whether you actually want to be modifying From and To unilaterally, which of course breaks RFC 3261 and is definitely not something proxies should do, that's another matter. I would say don't do it. -- Alex Balashov - Principal Evariste Systems LLC Tel: +1-678-954-0670 Web: http://www.evaristesys.com/, http://www.alexbalashov.com/ Please be kind to the English language: http://www.entrepreneur.com/article/232906
