0800 numbers going straight to a voicemail but not on my phone?

[MollyB2]

Today, I have found out that calls from an 0800 number to my mobile, were redirected instantly to a voicemail service.  I have no call diverts on my phone, the number is not blocked on my phone (checked that) and I'm rather concerned that neither the 0800 number or the voicemail message that they left, appears on my phone.  It would appear that both the call and the message have dropped in to an 02 abyss?  How can this be?  I have checked my phone settings and there is no block on 0800 numbers, no restriction on unknown callers, no explanation as to why this should be happening.  I have an iphone 15.

Numbers not in your contacts are redirected to Voicemail as of IOS 26.2  Have a look under the Hamburger menu in the top right, and then Unknown Callers..

Also to turn it on or off go to Apps, then Phone and scroll down.. 

This isnt an o2 thing but an Apple Improvement..

But it's not turned on by default and needs enabling by the user.

Hi thanks for your response.  So no hamburger (/) menu on iphone 15 and the silence unknown callers is switched off  so not sure what to attempt next?

Hi, my version is 18.6.02 and there is no hamburger menu on the phone.  So, with the Apps, Phone, and "Silence Unknown Callers" off - 0800 numbers should still come through.  But they are not.  betwixed and between 02 and Apple still?  🙂

Hi thanks for your response.  It is not switched on so still strange that this is happening.  There doesn't seem to be anywhere in the phone, Apps>phone>silence unknown callers is off, so not sure where to try next?

The usual fix for issues such as this is to ask customer service to disconnect your phone from the network and then reconnect it. This means being without connection for about 4 hours.
