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

04 Jan 2016
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” at the bottom of the app. It is usually due to one of below reasons:

1. The connectivity transition has not occurred on the device. Simply close and restart the iPlum app. (To close the app without deleting it on an iPhone or iPad, simply double click the home button, locate the running app and swipe it upwards. For ending the app on an Android device, press on the home key until the screens for the running apps are shown. Then swipe the app screen to the right to end the app.)

2. The other reason for connectivity issue is the port block or firewall set by your carrier to block voice apps like iPlum due to competitive threats. Wi-Fi too gets its internet via carrier so if a carrier has blocked the ports or put firewall, you will get an error using iPlum. Close the app and try to change the source of internet.

Fortunately, there are various VPN apps available in iTunes Store & Google Play which can help you get connected through the port block or firewall. If you need any specific help send us an email.

Note for 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)
