NEW Rings even when the app is closed

Your office line, in your pocket.

The 4voice app turns an Android phone into your work extension. A call comes in, the phone rings with Answer and Decline, and you take it from the street, the car or the couch. Chat, voicemail and your queues come along.

Closed app. Ringing phone.

Your extension is always reachable. A call to you sends a push, the app wakes and rings like a phone call, whether you opened it today or not. Tested on a real Android phone on cellular, 2026-10-01.

One call, from a locked phone to a live conversationLive demo

Follow one call from an idle phone to the keypad. Press any step to take over.

An Android phone sits idle with the app closed. A call from Bob, extension 101, arrives and the phone rings with Answer and Decline. The call is answered and a timer runs. Afterwards the app shows its keypad with the queue status.

Ringing: Answer or Decline, on a phone with the app closed.

Good to know

Questions about the app.

Does the app ring when it is closed?
Yes. A call to your extension sends a push that wakes the app, and the phone rings like a phone call with Answer and Decline. If the call is answered somewhere else first, or the caller hangs up, the phone is told to stop ringing. We tested it on a real Android phone on cellular on 2026-10-01: it rang, it was answered and the audio ran both ways.
Does it work away from the office Wi-Fi?
Yes. Calls from the app relay through our own servers, so they work on cellular and on ordinary Wi-Fi without anyone changing a setting.
Can I move a call between my desk phone and my mobile?
Yes. Press *6 during a call to send it to your mobile number, or dial *71 on the app to pull the call in from another phone of your extension. Both are available as add-ons, switched on per company.
What can a manager do from a phone?
The 4voice Admin app shows live calls, extensions, company logins, call history and a call report. Managers can force the schedule open or closed, and edit call forwarding, blocking, park, speed dials, departments, texting and holidays.
Does the app follow my phone's light or dark setting?
By default, yes. If you would rather keep one look, pin light or dark under Account, then Appearance.
