1. What is sivo?

“sivo” is a new feature that allows a Deaf User and the Hearing Party to see each other while on a VRS call. Both the Deaf User and the Hearing Party can also see the Video Interpreter (VI). The VI can also see both the Deaf User and the Hearing Party.

2. Is sivo only for ZVRS or Purple VRS or both?

sivo as a feature is available on both Purple VRS and ZVRS. In fact, you can use any VRS provider, even if it’s not ZVRS or Purple.

3. What do I need to do in order to be able to use sivo?

At a minimum, the Hearing Party (your hearing family members, hearing friends, or hearing co-workers) must download and install the sivo app to his or her iPhone, iPad, Android phone or tablet, laptop, or desktop computer. The Hearing Party must also register his or her ten-digit voice number inside the sivo app.

For a more seamless user experience, while using either Z5 or P3 VRS apps, you should also make sure that your app is updated to the latest version. With the latest version, you will see a sivo button when you are connected with your Hearing Party over Purple VRS or ZVRS.

4. What app does my Hearing Party have to download and install?

Tell your Hearing Party to go to the App Store and search for “sivo” to find the iOS app. For Android users, go to the Play Store and search for “sivo” to find the Android app. For Windows or Mac, simply visit to download sivo directly to your computer.

5. While on a VRS call with my Hearing Party, can I turn off the video with my Hearing Party?

Yes, you can turn on and off the video with your Hearing Party at any time. When you turn off the video, you will still be connected via VRS and can continue to converse with your Hearing Party (without video).

6. If my Hearing Party calls me first (e.g., V2V call), can we still use sivo?

Yes, sivo works in either case – whether you start the VRS call with your Hearing Party or whether your Hearing Party calls you. Once you two are connected via VRS, just click on the sivo button in the VRS app to connect on video.

If you do not have an app that supports this, ask the Video Interpreter to turn on the sivo video on his or her station.

7. Is there a guide on how to use sivo?

Download sivo User Guide  to receive a free step-by-step guide on how to set up and start using sivo.

8. Can sivo work with other apps and devices?

Yes, you can still use sivo even if you’re not using our Z5 or P3 apps, with the understanding that the sivo button would not be available. Instead, simply call through our dial-around number at 888.888.1116 (ZVRS) or 877-467-4877 (Purple VRS) to reach one of our Video Interpreters (VI), then ask that VI to start the sivo call for you once you are connected to your Hearing Party. The VI has his or her own button on the VI screen for this purpose.

9. Who do I contact if I have product or technical issues?
