How to Wi-Fi Call in Australia?

Are you aware that if mobile coverage is limited indoors, whether at home, in the office, or even in places such as shopping centres, you can easily make and receive calls and text messages over a wi-fi connection? If you’re in a poor coverage area, you may well have heard of Wi-Fi calling. If not and you have reduced mobile signal, then this is the guide for you.

How many times have you said “wait one second, I have to go outside, I haven’t got a good signal”. Great news!  Wi-Fi calling promises to be the fix. By using your home/office Wi-Fi enable internet service (ADSL2, Cable, NBN) you can place calls seamlessly.

How to enable Wi-Fi Calling?

Firstly, you will need an iPhone 6 or Android 4 (or later) and have updated your mobile to the latest version. To enable the service on the following mobile devices, follow the procedures below:

Apple iPhone 6 (or later)Wi-Fi Calling

1. Go to “Settings – Phone – Wi-Fi Calling

2.  Enable “Wi-Fi Calling on This iPhone” by   swiping the button to green.

 

 

Google Pixel (or late model native to Android devices)WI-FI CALLING

 

1. Open the Phone app on your device.

2. Tap More and select “Settings – Calls”.

3. Tap Wi-Fi calling on. If you don’t see this option, it’s because your carrier doesn’t support this feature.

Extra Information on Wi-Fi Calling

Q. Does using my Wi-Fi connection make the calls free like VoIP services such as Skype?

Unfortunately, not, they are still charged at your normal call rate.

 

Q. Does every carrier support this?

No, but the main ones do, see Telstra, Optus, Vodafone for more information.

 

Q. How much bandwidth & latency will I need to support this?

Between 100-120kbps maximum and 100ms maximum. This is the general rule for most VoIP/VoWi-Fi applications. So, if you’re not too far from your local exchange or still on dial-up modems, you should still be able to access the service.

 

Q. As the call is going through my home internet (or office internet connection), does it use my data allowance?

100% it uses your data allowance at 100kbps for a one hour call, so you could expect to use around 350-400mb, which is not a lot compared to one hour of Netflix 4K stream using around 56,160mb. However, still be cautious.

 

Q. If I answer the call on 3/4G/LTE and then connect to a Wi-Fi network, does the call transfer? Or the opposite, if I disconnect from the Wi-Fi network does the call move?

Yes, 100%. Even turning the Wi-Fi connection on/off really quickly switches the call between networks, you just may get a small pop/break in the service.

 

Q. I am at the airport/shopping centre and getting no signal from my mobile provider, can I join the free Wi-Fi and call work through Wi-Fi calling?

Yes you can!

 

Q. If you are overseas and are connected to Wi-Fi, will Wi-Fi calling work?

Unfortunately not, our local mobile carriers still must charge international roaming fees. If you are tech savy, find a decent VPN service, although tricky, it will work.

 

Q. My Wi-Fi calling is working at home, Starbucks, McDonalds, my local library and even on my friends Wi-Fi but it doesn’t work at my office, what do I do?

Tell your IT staff to “enable IP-SEC Pass-Through and Certificate Fragmentation support” (…..and quickly walk away before they ask you questions about it, because you have no idea what you just said). Most office/business networks will have extra security (firewalls) and your IT staff will be required to configure access for those services.

 

Q. How secure is Wi-Fi calling? If I am making a call over an open unencrypted Wi-Fi network?

We always recommend you do not use an open Wi-Fi network, in saying that the Wi-Fi calling apps send and receive using an encrypted tunnel, like a VPN service.

 

Q. I already have Cisco Jabra, Skype-for-business, x-lite, Samsung Mobility, Facebook Messenger, WhatsApp, WeChat and every other communication app on the planet, why do I want this on?

Wi-Fi calling has become a native feature (Android/iOS) of your smart phone and it is there to help combat low signal/dead spots where it is not possible to connect to 3/4G, but where Wi-Fi is available.
