+Subject: [PATCH] sip_parser.c:  Remove wholesale '[]' strip from
+ parse_param_impl
+
+The wholesale stripping of '[]' from header parameters causes issues if
+something (like a port) occurrs after the final ']'.
+
+'[2001:a::b]' will correctly parse to '2001:a::b'
+'[2001:a::b]:8080' will correctly parse to '2001:a::b' but the scanner is left
+with ':8080' and parsing stops with a syntax error.
+
+I can't even find a case where stripping the '[]' is a good thing anyway.  Even
+if you continued to parse and resulted in a string that looks like this...
+'2001:a::b:8080', it's not valid.
+
+This came up in Asterisk because Kamailio sends us a Contact with an alias
+URI parameter that has an IPv6 address in it like this:
+Contact: <sip:1171@127.0.0.1:5080;alias=[2001:1:2::3]~43691~6>
+which should be legal but causes a syntax error because of the characters
+after the final ']'.  Even if it didn't, the '[]' should still not be stripped.
+
+I've run the Asterisk Test Suite for PJSIP (252 tests) many of which are IPv6
+enabled.  No issues were caused by removing the code that strips the '[]'.
+
+I tried running 'make pjsip-test' but that fails even without my change. :)
+
+The Asterisk ticket is: https://issues.asterisk.org/jira/browse/ASTERISK-25123
