Can I use my Telstra T-Voice app outside of my house?


You can make and receive phone calls at someone else’s place as long as they are a Telstra customer with a compatible Telstra gateway.  To use your Telstra T-Voice App, you will have to register the App to their compatible Telstra gateway and be within their home Wi-Fi range. If you’ve previously registered the T-Voice app to another Telstra gateway, you’ll be prompted before connecting to the new gateway.


Note: Calling charges will be applied to the service number (home phone service) of that location. Your Telstra Home Phone or Bundle plan will not be charged. Your compatible smart phone or tablet will also receive all incoming calls for that location while in Wi-Fi range.

Making internal calls using Telstra T-Voice® App


When you set up the Telstra T-Voice app on your compatible smart phone or tablet, it will be assigned a number (1** - 7**). This number can then be used to make and receive internal calls between compatible devices in the home. These calls are free and are made by calling the device number then pressing ‘**’.

Numbering plan

  • 1** to 7** to individually call an individual smart phone/tablet with T-Voice installed
  • **1 to **6 to call an individual T-Voice 502 handset
  • **7 to call the phone wired to the gateway through the green phone socket
  • **8 to call the other phone wired to the gateway through the green phone socket (Telstra Gateway Max™ only)
  • **0 to call all the T-Voice devices, all the cordless handsets and any home phones connected to the green phone sockets on the back of the gateway


On NBN only, you can call the T-Voice 502 handset from the T-Voice app by dialling ** and its number. For example, **1 will call the first T-Voice 502 handset.



Managing Telstra T-Voice® App contacts


Telstra T-Voice can share up to 1000 contacts from your compatible smart phone and tablet with all other T-Voice enabled devices connected to your compatible Telstra gateway.

Troubleshooting tips for Telstra T-Voice® App


What happens when I go out of Wi-Fi range?


As you move further away from your gateway, the home Wi-Fi signal strength drops. The T-Voice App will begin to beep when you are almost out of home Wi-Fi range. You will then have a few seconds to walk back into range to maintain the call. The call will end when you go out of Wi-Fi range.


When you walk back into Wi-Fi range the T-Voice app will automatically connect you back to the gateway. You will not have to step through the setup wizard again to connect back up to the gateway.
