Common Issues

  • Can’t make or receive calls

Start Here

1. Check Your Internet

VoIP needs a stable connection.
If your internet is down or slow, fix that first.

Switch everything off, then back on in this order:

  1. Router
  2. VoIP device

3. Check Connections

  • Cables plugged in properly
  • No damage
  • Handset powered

4. Using an App (Zoiper / GS Wave)?

  • Must be connected to WiFi or mobile data
  • Status should show Ready / Green

5. Check Registration

Not registered = no service
Check your VoIP details in Client Zone
