Message:

Initial fixes for ticket #747: bugs in parsing SIP torture messages (RFC 4475):

• SIP version components may be separated by whitespaces (e.g. "SIP / 2.0")
• parsing of mangled header when for unknown/generic header
• Via parameters were parsed with paramchar rather than token
• handling NULL character inside quoted string

Some torture messages have been added in the Python test.
