Hi.

For about the past 1 month now I have been experiencing considerable call quality issues. I have a Samsung A8 phone with stock Android acquired via Vodafone. A few times now the call has started low quality and several minutes into the call it switches to HD Voice quality. When the call is in HD Voice it can sound quite siblant and occasionally get a bit of static/crackle.

Yesterday I was on a 12 minute call and it kept switching between HD Voice quality and low quality. It probably did it about 10 times during the call. I asked the caller if the call quality was changing on his end but he said no, I was consistently the same throughout the call.

I also noticed the other day an advertorial on Newstalk ZB and the person being interviewed, their call quality was also exhibiting the same issue I have.

Anybody else experiencing this or do I possibly have a dodgy phone?

At the about the same time this started I also had data issues with my phone where app updates wouldn't download, so ended up factory resetting my phone, but that hasn't stabilised the call quality.

If you can't laugh at yourself then you probably shouldn't laugh at others.

Were you mobile at the time or stationery? Doubt very much it's a handset issue

I was stationary. Primarily at home in West Auckland, but for call yesterday I was in East Auckland.

Were you near the water? Sounds like the call was handing off between different cell sites

No. Indoors and places I was at is about 1-2km to nearest body of water.

Does phone support VoLTE and can you lock phone to 4G only? Also was this Vodafone to Vodafone, or Vodafone to off-net?

Yes phone supports VoLTE and I have that symbol showing on my home screen. No can't lock phone to 4G. I have 4G/3G/2G (auto) or 3G/2G (auto), 3G only and 2G only.

The call I had yesterday was VF to VF.

I’ll be honest and say I don’t use my phone for voice particularly often, but I happened to be at one of our sites in East Tamaki the other day and call quality was atrocious. Disconnected and redialled and seemed marginally better. Also VF to VF.

These calls need to be called at in the tracing tool and see what is happening to them or we are only guessing

So how do I do that or is that something that Vodafone has to initiate?

Vodafone technology would need to investigate (good luck getting a ticket to them)

I can hear the call now

(1) You need a new SIM card (2) Send your phone in for repair (3) Turn your phone off and back on a try again

Clue issue is with none of the above

Either that, or "I'll transfer you to someone who can help..."

...

"Hello, Vodafone Collections, how can I help you?"

coffeebaron: Vodafone to off-net?

There is a ton of work happening in the interconnect space, so i expect this should drop off as being a factor soon :)
