Subject: [PATCH] MWI for Multi Registrations on Multi Profiles

Sometimes you can have multiple registrations for the same extension across multiple SIP profiles. This adds the functionality to fire an event for each unique SIP profile. I also added a check to see if we have already send an event for a profile since you don't want multiple events fired one SIP profile.
