Hello!
It was accidentally noticed that the variable $fU gets the user part of
userinfo SIP URI (although it is logical and described in the document
RFC2543).
I got message below and my spam filter based on $fU passed it inside the
network, as $fU was test
From: <sip:test:test@1.1.1.1>;tag=123456
Sure I can filter it through a regular expression, but maybe it's worth
adding another core variable with the userinfo value?
SIP-URL = "sip:" [ userinfo "@" ] hostport
url-parameters [ headers ]
userinfo = user [ ":" password ]
