Always have issues when I make a call to companies that use "internet" call systems.

[SSThing]

I have had this problem for years and across 4 different handsets. 

If I make a call to a person/company that uses an Internet call system at their end, I have constant issues. 

For example, if I call my local council, the majority of departments are working from home, so they are then distributing the calls out (via internet) and the problems begin.

If I am on speakerphone my end they struggle to hear me. If I switch back to phone speaker mid call, I can hear them but they cannot hear me at all (so invariably I have to call back). Or, most annoying, the audio they hear cuts out whenever I say a number, so communicating account numbers etc is impossible (a lot of the time it drops a specific number every time I say it). 

Because I have this issue across multiple handsets, I have to guess that the issue is between Three and whoever I am trying to call? 

Are there any settings on my phones (all recent Samsung Galaxy) that I can change that might help? 

Any other suggestions?

Thank you.

Thank you everyone. 

I'm definitely not using wifi calling myself, so I can rule that out but I will definitely check to see if any mic options become available next time I am in a problematic call. 

I would say that the vast majority of problems begin when I initiate or receive a call and I try to use "speaker" on my phone and the recipient of the call is either (I'm guessing) using voip AND (again I'm guessing but it's most likely with people working from home) a headset. They struggle to hear me (frequent cut outs) but I can hear them perfectly. If I then switch off the speakerphone, 99% of the time the problem then gets even worse and I invariably have to hang up and dial again. 

I do sometimes use an Anker Bluetooth Powerconf device which works perfectly most of the time but has exactly the same issues if the person on the other end is using voip/headset. Actually, now I am typing this I can recall that when I ring my local pharmacy, if they pick up the phone there's no problem but if one of the staff answers via their headset, they can't hear me (I can recall having to call them about 20 times until I managed to actually have a conversation and it was the pharmacy who explained that most of the time they used headsets and that they were definitely using voip at their end). 

The thing that really confuses me is when I am reading out something such as an account number and every time I try, when they repeat it back it has cut out on a particular number and it will be the same number every time, almost as if their system is listening for numerical prompts (to redirect to another department?).

Hello there. 

Welcome to the Three Community. 

That's strange. I'm wondering if it's a combination of noise cancellation on the phone, and bandwidth restrictions/compression of the internet based calling service. 

A couple of things that might be worth trying - when making a call, check to see if a Mic setting pops up within the notifications panel when you pull down twice from the notification area. Have a play around with whichever settings are available to see if any make a difference. Another thing is to check to see if you're using Wifi Calling, if so, turn it off and try making the call again to see if things improve.

Hello
I think I experienced this or similar before. I think was on cellular calling and I reckon the other side/company was using VoIP system... Initially the 1st minute of the conversation was ok, but at some point when I queried the other side it took like 10-15 seconds to ear something back, like it was lagging behind, in short the conversation was not fluid and was getting worse. we agreed to try again a phew times and the same over and over, regardless who had started the call. I think after the 5th attempt I switched/forced wifi calling on and then it went ok.
So I can only think or guess it could have been something around the cellular network/coverage or I am now thinking the codecs being used either by Three and/or the company I was calling to.

I have this exact same issue (iPhone 16 Pro). It must be an issue in the network rather than the handset, because regular calls (to my family for example) work fine.
