Calls from Poland to UK Landline Not Connecting

[Hoodedoracle]

For the last two weeks we have had the same problem.  We can make a call to POLAND using our landline (DIGITAL PHONE), but those in POLAND cannot call us in UK?

We can call our phone, as can others in the UK.

They can call others in POLAND as can others in POLAND call them in POLAND.

We have had to resort to using WhatsApp on our mobiles (luckily I have unlimited data).  

The annoying thing is that we have the landline solely for contacting those abroad who struggle with mobiles.  There is definitely a fault somewhere - as I can see similar queries raised on GIFF GAFF, O2, 3 and other providers.

Hello @Hoodedoracle ,

Welcome to the community,

Are they making sure that they are putting +44 or 0044 in front of the number and leaving the 0 off the number, I mean instead of ringing 021… they are using +4421… as an example for making calls to the UK, if you get what I mean? Otherwise I have no idea why it is not working and it must be something to do with Poland, nothing to do with UK, which we can solve, they would have to speak to their providers to find out why, otherwise.

I believe this post was originally added, in "me too "style, to a thread regarding roaming in Poland, before being split into its own thread.

Can your Polish contacts call you on other UK numbers? Do you have any issues with receiving calls from other networks in the UK? That includes landline operators as well as mobiles.

If you know customers of other UK operators who have similar issues, it lends itself to an interconnect issue. The Polish customers should be reporting this to their providers - there are processes in place to investigate this sort of problem.

It was working fine up to 24th of Oct 25 - when it started to cut out after 30 mins - then after that date - they have not been able to call our number?

[Hoodedoracle]

According to them - they have no issues calling other countries, or anyone else in Poland... just calling us?

and NO they are not blocked by my call barring/preference.

We can call them from our landline.

We can speak using WhatsApp, we can Video Conference using Teams - all without problem 

But they are elderly and prefer the landline as they struggle when on their own to use modern tech.

I think it is likely their end, but why - but I have seen similar issues with other landline providers online being reported.

Hi again @Hoodedoracle.

I can see you've mentioned checking your blocking settings and these all look fine, but do you happen to know if you can receive international calls from other numbers?

It is possible to block these outright, as well as blocking individual numbers, but we don't block on a country by country basis, or based around connection type. 

It could also be worth selecting this option to block international calls, wait a bit of time, then remove the block to see if this resolves things. 

If you continue to struggle from there, I would recommend giving our team a call, and they can help you investigate further.

Hi.

I have checked our 'international blocking' and it is not activated.  - Also I have done your test - and turned it on, then off again after a considerable time.   The same issue persists.

There is nothing wrong with our line (or broadband, except it being slower than I would like - cannot wait for FTTP to arrive under the installation program - aka soonTM)

I have checked blocked options and their number is not blocked - nor is international as already stated.

This suddenly started issues around Oct 24th 2025.  with calls being cut short - no not working.  

Family in Poland have done their checks and their provider is adamant it is not a fault or blocked their end, as is ours...  it is frustrating to say the least.

Thanks for the update here, @Hoodedoracle.

If things still aren't working after all of these checks from your end, I would definitely recommend giving us a call so we can get this investigated further.
