Why I can’t connect or make calls using Wi-Fi or Carrier data?

If you are not able to make calls using Wi-Fi or Carrier data you will see a gear moving at the top right corner in the app or “Registering Error” at the bottom of the app. It is usually due to one of below reasons:


  1. The internet connectivity transition has not occurred on the device. Close and restart the iPlum app.

  2. In certain cases the port block or firewall set by your carrier or wi-fi provider may lead to connectivity issues. Close the app and try to change the source of internet or use a VPN app on your device. There are many VPN apps which you can find in iTunes or Google play.

Corporate users: If you have Cisco Firewall ASA 5505 family, make sure to switch off sip_policy. Configuration >> Firewall >> Service Policy Rules >> Inspection Default >> edit > Rules actions (tab) > Protocol Inspections (tab) > Sip (Uncheck it)



Important: You can also use Carrier Calling for your iPlum calls:
