Patch: Allow "~" in SIP header token #13

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
P2P-SIP doesn't allow "~" character for tokens in headers, so it sends quoted 
strings (see To tag):

Attached patch fixes this.

According to RFC3261:

To        =  ( "To" / "t" ) HCOLON ( name-addr
             / addr-spec ) *( SEMI to-param )
to-param  =  tag-param / generic-param
tag-param =  "tag" EQUAL token
token     =  1*(alphanum / "-" / "." / "!" / "%" / "*"
             / "_" / "+" / "`" / "'" / "~" )
