Does the SIP grammar consider differently-cased resource identifiers to
be equivalent?

Hi,
sometimes UAs do subscriptions using mixed case uris which most of the
times leads to NOTIFY messages not getting to the UA.
if used with subs_db_mode = 3 and a case insensitive dbengine it works.
however, if we use other value on subs_db_mode it doesn't work or
behaves poorly (missing cache)
should we make string insensitive matches in presence module for uris ?
i marked the 10 occurrences with >>>
Thank You
