## About

CallerLite is a native SIP softphone for macOS, built with its own SIP/RTP stack in Swift and a SwiftUI interface. It handles incoming and outgoing calls, hold, call transfer, mute and a DTMF keypad.

It includes favourites and contacts with quick search by name or number, a call history with missed calls, and a callback list. Availability can be set to available, away, busy or Do Not Disturb, and unwanted calls are rejected silently.

The SIP password is stored in the macOS Keychain and data stays on the user's Mac. A demo mode lets you try the app without a server. Version 0.1.0 requires macOS 13 or newer on Apple Silicon, uses SIP over UDP and supports G.711 (PCMU/PCMA) codecs. The app is not yet notarised by Apple, so the first launch needs approval in System Settings.
