Thanks for confirming that @5progface.
When you actually call 1571 to listen to your voicemail, does this give the actual number that called?
Also if possible, have you had the chance to try connecting a different phone to see if the same issue occurs with this?

@5progface I have Digital Voice myself and gave this a test, and it's not something I encountered.
When leaving voicemail, the missed call history was always showing the number of the caller.
If you get back in touch with our team they'll be able to check on how everything is configured at our end, but we can't rule out it being linked with the handset too.

Received a call from a family member this afternoon.
The correct telephone number was shown on bt handset and in my online calls log.
I am now waiting for the next call to be forwarded to voicemail and check again.
