YunZheng Voice
A softphone for any SIP phone system. YunZheng Voice is a free SIP softphone for your computer and your phone. Add an account from your office phone system or your provider, or sign in with YunZheng and your extensions and YunZheng Voice numbers are added for you. Incoming calls open a call window on the desktop and ring like a phone call on your mobile. Built on Orbit.

What you get
Works with any SIP phone system
Add SIP accounts from your office phone system or your internet phone provider: a name, the SIP address and the password, with advanced settings when your provider needs them.
YunZheng Voice numbers
Sign in with YunZheng and your personal phone, your extensions and your YunZheng Voice numbers are added automatically.
Several accounts at once
Every account stays connected on its own. Choose on the keypad which one a call goes out from, and see which one a call is coming in on.
A call window on the desktop
Incoming calls open a small window in the corner of the screen with Answer and Decline, while you work in another app.
Calls on your phone
On Android, incoming calls ring full screen, like any phone call. On iPhone, calls use the phone's own call screen, including on the lock screen.
Everything a call needs
Mute, hold, keypad tones and transfer. Put a call on hold to answer a second one.
Call history
Every call placed, received and missed, with a Missed filter and one click to call back.
Voicemail
Listen to your YunZheng voicemail in the app; for any other SIP account, one click calls its voicemail number.
Contacts
Names and numbers or SIP addresses, kept on the device.
Your audio devices
Choose the microphone, the speaker and the device that rings.
Keyboard first
Type a number from anywhere in the app to dial it; one key answers, or calls the number typed.
Always ready
Keeps running when the window is closed so calls still ring, opens at login, and follows light or dark mode.
