Summary:                    sip register: reserved character check not RFC 3261
compliant
Description: 
The checking of reserved characters within chan_sip.c is not RFC 3261
compliant.

According to the RFC there are different reserved characters for username
(* auth user), user (* username), password (* secret) and hostname (see
below).
chan_sip compares all above values against the SIP_RESERVED variable which
is defined as ";/?:@&=+$,# ".

This bug avoids registration to sip providers using allowed special
characters within the user part or the authentication user (eg.
bluesip.net, they use a '/' wihtin the auth user).

A backport to the 1.6.0 branch, which is affected also, would be great.

Just use FreeSWITCH, it's a lot better.

Asterisk is worthless and broken software.
