macOS SIP softphone
Cocktel keeps ordinary calls simple while giving professionals the controls they need for demanding deployments: multiple accounts, conferencing, transfers, prioritized audio devices, network recovery, call history, and per-call SIP trace capture.
Shape
Routine calls should stay routine. When the environment changes, Cocktel exposes the relevant state: audio profiles, registration health, network conditions, call journal artifacts, and SIP capture from inside the TLS session.
Modes
For people who just need a dependable macOS softphone: choose an account, pick the right audio profile, call, conference, transfer, hang up.
For PBX people and SIP operators: inspect registration, capture signaling per call, keep traces separate from conferences, and understand what happened after the call ends.
Capabilities
Keep separate SIP identities available without turning the main window into a control room.
Handle real phone work without needing a browser tab, a desk phone, or a second app.
Prioritize headsets, speakerphone, and roaming setups so Cocktel can recover upward when better devices return.
Registration, DNS, VPN, and route changes are treated as normal operating conditions, not exotic failures.
Capture signaling per call leg, including TLS sessions from inside the client, with user-controlled auth redaction.
Keep duration, route, codec, packet health, and capture metadata attached to the right call.
Spoken labels and state values are kept concise so the app remains usable without duplicating every visual phrase.
Signed, notarized, Sparkle-updated, and designed around macOS permissions instead of fighting them.
Diagnostics
Per-call captures, TLS events, registration state, audio route changes, and call journal records stay tied to the call they belong to. Troubleshooting should not require reconstructing a session from one global log.
