This seems a completely novice question, but nonetheless it has me stumped. I am merely trying to log into to my Asterisk server locally on my company's Intranet, using free SIP software (I've tried 3CX VoIP Phone and QuteCom). However, for the life of me I can't figure out where to define a USERNAME and PASSWORD for an Extension in the FreePBX administration interface, or in the various Asterisk .conf files.

I defined Extension 191 (config shown at bottom), and assigned it to an Incoming Route (which I doubt is relevant to merely connecting to the Extension). In the Device Options section of the Extension config page, there is a field for the password (secret), but not for a username/userid. I could not find any place in FreePBX to define an actual user, and all of the SIP software I've seen requires a username in addition to the password. What am I missing?

Many thanks to anyone who can be of assistance!
