Extensions
The Extensions page is the tenant-level list for creating, finding, editing, importing, exporting, and deleting extensions. Open it from Configuration > Extensions.
The page works against the tenant currently selected in the top bar. The screenshotscreenshots showsshow ten fake demo extensions, numbered 100 through 109, with a mix of chan_sip, PJSIP, custom, and virtual extension types. SIP and PJSIP usernames use the extension number followed by the tenant code, for example 100-CANISTRACCI. Password values are masked in the screenshot.screenshots.
