+Subject: [PATCH] sip_parser.c: Allow brackets in via parameters
+
+From RFC 5118 section 4.5:
+
+  While it would be beneficial if the same non-terminal
+  ("IPv6reference") was used for both the "sent-by" and "via-received"
+  production rules, there has not been a consensus in the working group
+  to that effect.  Thus, the best that can be suggested is that
+  implementations must follow the Robustness Principle [RFC1122] and be
+  liberal in accepting a "received" parameter with or without the
+  delimiting "[" and "]" tokens.  When sending a request,
+  implementations must not put the delimiting "[" and "]" tokens.
