How many user registered and connected without Qualify?

HI everyone,

I need to know how many users are actually connected on an Asterisk Server in SIP.
The command sip show peers and the qualify options don’t help me because I’m using a stress tool and that qualify doesn’t work in my case.

I tried to send OPTIONS message temporally to the Asterisk and it answers me with 200 OK. (This is the exact contrary or the qualify actually). However, even if the Asterisk answers 200 OK it doesn’t seem to keep the connection active betwen it and the user.

IS it normal? If yes, is there any solution to know exactly how many users are actually registered and connected o the server but without qualify?

Thank you
Best regards,
