Advanced Calling: VoLTE und WiFi Calling

Hello!

Super! I’m glad that Swisscom doesn’t sleep when it comes to introducing new services!

Now my question! I have an iPhone 6 with iOS 8.4 Beta 4. Now I see Voice & Data for 4G under the “Mobile Data” setting.

Does this mean that VoLTE is supported from iOS 8.4? This update would come out on June 30th? Or will it only be supported with iOS 9?

Hello
This is already displayed this way under iOS 8.3. Is not new from 8.4.

Greeting

In principle, some devices would already be VoLTE compatible.

See here: http://en.wikipedia.org/wiki/VoLTE#Devices (but there are probably some other devices)

Let’s see if the devices in the Swisscom network use VoLTE (my Windows Phone is currently still using 3G (CSFB)). The same device was already using VoLTE in the USA last year.

Ah ok! Thank you for the answer. I didn’t pay attention in 8.3.

For WifiCalling I understand that you need a software update, but do you also need this for VoLTE in this case? Or does the network operator software just need to be updated to support VoLTE?

Hello everyone

To benefit from VoLTE you need:

• a 4G/LTE-capable device of the latest generation and a software update from the device manufacturer: this year, devices from Apple, HTC, Samsung and Microsoft, among others, will support Advanced Calling
• one of the following subscriptions: NATEL® (xtra) infinity, NATEL® (xtra) infinity plus or NATEL® entry
• Activation of Swisscom; Swisscom informs all customers who will now be able to benefit from “Advanced Calling” via SMS

According to a press release, only the Samsung Galaxy S5 has currently been activated for VoLTE by Swisscom (June 10, 2015).

LTE-capable Windows Phones with operating system version 8.10.14147.180 or higher support VoLTE, but have not yet been activated for VoLTE by Swisscom. That’s why VoLTE works with Windows Phone in the USA, but not yet in Switzerland.

Hello

Thanks for the answer, although it doesn’t really answer my question. Are you only enabled for Advanced Calling if you support both Volte and WifiCalling or is just one of the two sufficient?

I’m assuming now that the iPhone will receive support with iOS 9. Since you won’t get an answer otherwise…

“Advanced Calling” is the marketing department’s collective term for VoLTE and WiFI calling.

- If a mobile device supports telephone calls via IP data packets via LTE, we are talking about VoLTE.

- If a mobile device supports telephone calls via IP data packets over WLAN, this is called WiFi calling.

VoLTE and WiFi calling are activated individually by the mobile operator. The mobile device/SIM card can be enabled for VoLTE but blocked for WiFi calling.

IPhone 6 and 6 Plus with the current operating system version as of today (June 10, 2015) supported VoLTE, but have not (yet) been activated for VoLTE by Swisscom:

https://support.apple.com/en-sg/HT203078

Currently (June 10, 2015) no mobile device has been activated by Swisscom for WiFi calling.

Is there already technical information about which IP addresses the smartphones communicate with for the WiFi calling function?

I imagine that there are situations in the business sector where one does not want to release the network for this purpose for various reasons, just as there are good reasons for WiFi calling. (But that’s a different discussion and doesn’t interest me…)

I type IPv6 (in the background).:smileywink:

And if I understand the concept correctly, it doesn’t really matter. Because VoLTE and Wifi calling is nothing other than VoIP.

I have a Samsung Galaxy S5 LTE+ SM G901F

Swisscom wants to send an SMS to all activated customers, I haven’t received that yet.

What does it look like for prepaid customers? Will this service also be activated?

It would be interesting to know whether Wifi Calling also works abroad, for example in a hotel, and whether you could then use it to make calls via Wifi instead of the IO app.

Will be introduced gradually, so just be patient…

No, you can’t.

Unfortunately not “yet”. However, this should also be activated at a later date.

Thanks. Are you already in the pilot?

No

Hello everyone

Also for prepaid?

- An expansion to prepaid is planned, without being able to specify a date at the moment.

Why is WiFi calling not possible abroad?

- With the introduction of WiFi calling, we are aiming for better reception quality in buildings. In a further step, we would like to offer this expansion abroad as well. The technical requirements for this are being worked out. Free telephony and messaging abroad is already available to our customers today with our communication app iO.

Thanks for the answers Swisscom. Another technical question that surprises me.

If I understand it correctly, the best network should be selected automatically, even if you are in a call (without interruption). Where I live, I practically only have 2G reception around the house. What happens when I leave the house? Will the connection continue with 2G without interruption or is there an interruption because there is no 4G?
