Poor coonection during landline calls

[Danno]

I have been having issues with calling landlines. I can usually hear the person on the other end but they can't hear me. This issue is only a calls to landlines problem as calling mobiles is always fine. 

This was happening on my previous sim and phone and I expected an upgrade to resolve the issue with a new sim card and new number, unfortunately the problem still occurs. 

I've called Three and they're unsure of the issue.

Hi Jonathan,  thank you for replying. 

Appears to be quite a few people having the same issue. 

It's all landlines, I can hear them but they cannot hear me it just breaks up, cannot be my signal as it is great for calling mobiles, it's just landlines. 

I've had the sim card changed, I've knocked WiFi calling off, and my friend with the same handset had the exact same problem, appears to be the handset on 2 different S23 ultra,  though not sure about everyone else.

I have the same issue as the others and don't have WiFi calling enabled, full signal 5g, and it only affects landlines. 

I'm only calling businesses for this and given they can only hear every other word I say for the topic I'm calling to discuss, I'm not about to ask them what provider they use for their business... 

Help please, as this has been going on for many months now and multiple phones, sims, etc.

Im struggling to get help from them, I've been to the shop and they have changed sim card etc, they just say must be poor signal,  paying all this money for contract and phone is unusable to make phone calls,  I'm pleased it's not just me though, so doesn't doing like it's just the hanset

Hi Jonathan, it's affecting all landlines that I ring, business and personal,  I've tried a few things with three through their help and nothing works, I cannot use my mobile for any calls to any businesses or personal they all say they cannot hear me and it's a very bad line

I have looked at coverage and network checker and there are no reported issues. Only thing I haven't done it turn off wifi calling. I have made calls when not connected to WiFi when I'm out and it was still the same.

Hey Danno,

Thanks for getting back to me.

Could you turn off Wi-Fi calling and let me know if it's still the same?

Also, do you find any call you make to a landline, while out and about, is the same, no matter the location?

Could you also provide me with the make and model of your device, please.

Thanks,
Kate

Hey Danno,

I'm sorry to hear you're having trouble with calling landlines, this must be frustrating.

Did you try following the steps as advised by @tarantella , at all?

Could you also pop your postcode into our Network Status Checker and let me know if any issues are reported in the area, or work currently taking place, please?

Thanks,
Kate

Try switching off wifi-calling and see if that helps.

If you haven't already, put your postcode into the coverage checker.

Also, check network status in your area to see if there's any ongoing work or maintenance. 

Failing all of that,  have a chat with Customer Services. 

If none of that helps,  raise a complaint.

I've tried turning the phone on/off, I've manually selected on the sim settings Three; and the area checker is showing as no faults in the area. 

The only thing I haven't done is turning off wifi calling, however I've called landlines when I'm not connected to WiFi anf had similar issues.
