The softphone, rethought

Professional calling.
Consumer-grade polish.

Everything a desk phone does, none of what makes SIP apps feel like 2009. You'll see “Work line ready”, never “REGISTER 200 OK”.

HD voice with a live waveform

Opus wideband audio, echo cancellation and a waveform that moves with the voice on the other end, so you always know the line is alive.

Video, with consent

Your camera never switches on by surprise. Accept with audio first, turn video on when you're ready.

Every line, one app

Work, personal and a shared queue side by side. Pick the line per call, or let the app choose.

Transfer, merge, hold

“Transfer” or “Speak first”. Add a call, merge into a conference, swap between them with a tap.

Presence that means something

Green, yellow, red, grey: see who's free before you call, synced from your PBX.

Private by design

TLS signalling, SRTP media and a lock that tells you when a call is encrypted. SIP passwords live in the iPhone Keychain and never touch our servers. Sign-in is by passkey or a one-time code.

Messaging

Chat like WhatsApp.
Stay on your company line.

SIP messaging that finally feels modern: read receipts, typing indicators and rich media, all on the same extension you call from.

Love that, see you Friday 🙌

Say it face to face

On my way!

Drop a pin

Send where you are as a map picture with a one-tap Maps link, so visitors never get lost in reception.

Delivered over your PBX, not a third-party cloud.

Try it

Go on,
make a call.

Tap the keys, or type on your keyboard. The keypad is a floating sheet in the app, not a tab you'll never use.

Your sidekick

An assistant that
knows your calls.

Ask what you missed, who called about what, or have it place the call for you. It works from your history and messages, and asks before it acts.
