How iNdex Voice works

Your company phone system, in an app

Customers call your business number from any phone. iNdex Voice routes the call the way you configured it, and your team answers in the iNdex Voice app.

1. Sign up and create your company

Create an account at voice.indextech.co.za and enter your company name. We set up a main call flow, office hours (Monday–Friday, 08:00–17:00) and voicemail for you.

2. Choose your business number

Search by area code and pick the number you like. It rings as soon as the phone company has approved it, at most 3 working days. You can also ask us to move (port) your existing number.

3. Add employees and extensions

Invite your team by email. Each person gets an extension such as 101 or 102. You decide who can manage settings.

4. Install the iNdex Voice app

Each employee installs iNdex Voice from Google Play and signs in with their invitation. Their phone is now registered to receive business calls. Prefer a computer? The web app works in Chrome, Edge and Firefox.

5. Customers call — your team answers

When a customer calls, the app shows a full incoming-call screen with the caller's number. Answer, mute, hold, transfer to a colleague, or end the call. Missed calls go to voicemail.

6. Fine-tune your phone system

In the web portal, add an auto-attendant ("Press 1 for sales"), ring groups, queues, public holidays and forwarding rules — no technician required.

What you need: an Android phone (Android 8 or newer) with mobile data or Wi-Fi. Calls use your internet connection — a stable 3G/4G/5G or Wi-Fi connection gives the best quality.
