the caller I’d had stopped displaying names and numbers was working fine until about a month ago also the ring tone changes after the second ring have tried *234# it is saying calls will be displayed any ideas would be appreciated thanks
I have had the same problem with Caller ID not working after it had always been working before. This only affected one phone, a BT Decor 2200 corded phone. It happened around 29 July. I can pinpoint this date because my other phones (Panasonic cordless) are still showing Caller ID.
Has there been a change to the Caller ID signal format.
