Subject: Correct RPID parsing for unquoted display-name.
X-Git-Tag: 1.8.22.0-rc1~30
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=68d2599d3958d0850511a746bd4e89c2dc2a04a0;p=thirdparty%2Fasterisk.git

Correct RPID parsing for unquoted display-name.

Parsing Remote-Party-ID will now succeed if display-name is of the
*(token LWS) kind and not just the quoted-string kind.
