   4 Subject: [PATCH] sip_parser.c: Allow brackets in via parameters
   5
   6 From RFC 5118 section 4.5:
   7
   8   While it would be beneficial if the same non-terminal
   9   ("IPv6reference") was used for both the "sent-by" and "via-received"
  10   production rules, there has not been a consensus in the working group
  11   to that effect.  Thus, the best that can be suggested is that
  12   implementations must follow the Robustness Principle [RFC1122] and be
  13   liberal in accepting a "received" parameter with or without the
  14   delimiting "[" and "]" tokens.  When sending a request,
  15   implementations must not put the delimiting "[" and "]" tokens.
