cokemaster: With VoLTE and VoWIFI, the voice channel is fully packet based while WCDMA (3G) is circuit based.
The only handover that exists is VoLTE -> 3G. It’s a one way trip once that occurs eg. It won’t hand up to 4G.

You can however go back and forth from VoLTE (4G and 5G) and VoWifi with no problems.

Any updates? I had a few calls randomly drop at the office yesterday and today (I have decent 4G VoLTE coverage where I am).  Hopefully not too much longer 🫰🏽🫰🏽

Geektastic: Are they still planning to turn off 3G?

There are plenty of areas here in Canterbury where there’s only 3G at least according to what shows on my iPhone 13.

@Geektastic SparkNZ have made no announcement for turning off 3G 

Spark chief executive Jolie Hodson said it expected to announce plans in the next 12 months to also switch off its 3G network, and expected it would give at least one year’s notice of its closure date.

Noticed today that the Samsung Galaxy A13 is now on the compatible list for Wi-Fi calling. This is our current fleet phone so have been doing some testing with it today. I use Wi-Fi calling with my personal Vodafone connection on a S21 but work is with Spark, so testing for specifics for the inevitable staff questions/problems.

It requires the 1 October update, which has only been available for our devices the last week or so.

Manually needing to enable Wi-Fi calling in settings is going to be annoying, another thing to add to comms to staff for when setting up the device.

The toggle to turn on Wi-Fi calling only shows with a SIM inserted, and is remembered by the phone on a per SIM basis. E.G Insert SIM A, turn on Wi-Fi calling. Remove SIM A, insert SIM B, Wi-Fi Calling is off. This is also reflected with the dual SIM slots, if SIM in slot 1 is on and 2 off, if you swap the positions, 1 becomes off and 2 on. So you can't set it up with any Spark SIM and then send it to staff for putting their own SIM in and expect Wi-Fi calling to still be on, each SIM needs to turn it on manually in settings.

Handover from a Wi-Fi call to a VoLTE call has around 1.5 - 3 seconds of downtime in the call audio, which seems mostly fine to me. You can't enable Airplane mode with a call in progress, so haven't been able to test VoLTE to Wi-Fi. Need to find a cell signal dead spot that has still Wi-Fi coverage. Going from Wi-Fi to a 3G call drops as expected.

Call quality and audio seems fine/normal.

So yeah, glad it is here. It is going to solve a couple of issues with have with coverage. Just wish SMS was working over it, that is a real pain/gotcha I'll need to let staff be aware of. Hopefully when that gets enabled it won't require any setting changes, though I am guessing it will require another security update.

cokemaster: Someone needs to make a meme re: ongoing lack of SMS over wifi. I would have expected them to solve that ASAP.

iOS 16.1 enabled today. Wifi Calling seems to work fine on both Skinny and Spark. Very happy as our house is a bit of a blackspot for cell reception.

I'm having issues at home with iOS 16.1. Worked fine on work wifi today.

Looks like pihole may be blocking it as once I disable it and toggle wifi calling it shows up. I'm running dual sim with 2D and wifi calling has always worked fine. Anyone seen anything similar?

rscole86: Have you checked the pihole logs to see what it's blocking?

The plot thickens. Having a proper look at logs and playing around it seems PiHole is not responsible and was purely coincidental, I can't see any DNS requests that relate to WiFi calling (that I know of).

If I put the phone (12 mini) in Airplane mode WiFi calling comes up, when I turn off Airplane mode it disappears. Meanwhile 2D shows WiFi Calling the entire time.
