Hello,

I have Sip header that has multiple commas in it. Something like this From: "1234567890,,,3"<1234567890,,,3@nonet.net>;. I am using Net::SIP::Packet to parse the packet and best I can tell from the RFC 3261, multiple commas are legal as long as they are quoted or in < > brackets.

Here is the relavent code form Packet.pm in _hdrkey_parse_comma_seperated

while (1) {
                        if ( $v =~m{\G(.*?)([\\",])}gc ) {
                                if ( $2 eq "\\" ) {
                                        $v[-1].=$1.$2.substr( $v,pos($
+v),1 );
                                        pos($v)++;
                                } elsif ( $2 eq '"' ) {
                                        $v[-1].=$1.$2;
                                        $quoted = !$quoted;
                                } elsif ( $2 eq ',' ) {
                                        # next item if not quoted
                                        ( $v[-1].=$1 ) =~s{\s+$}{}; # 
+strip trailing space
                                        push @v,'' if !$quoted;
                                        $v =~m{\G\s+}gc; # skip space 
+after ','
                                }
                        } else {
                                # add rest to last from @v
                                $v[-1].= substr($v,pos($v)||0 );
                                last;
                        }

I want to either submit a bug, or I will create a local copy to modify for this potentially ill-legal formatting.

Thanks, gman
