[Freeswitch-users] user registration

Hello I am using freeSWITCH 10.06 and i am wondering about the difference between 2 commands : - show registration - sofia status profile internal reg both commands list the users registered, but sometimes, I am still seing users in show registrations whereas they are not present in sofia status. which is the command to have the right registration status ? what is the difference between these commands ? thanks regards
