Hello DavidSt1
Thanks for your post and welcome to our community.
Sorry to hear about the caller Id going missing
For some reason this can occur after faults in the area
It's an easy fix though, we just need to arrange for a service engineer to come out
I am more than happy to take a look at this for you
I will need to send you a private message to pass security
If you can check the purple envelope top right of your screen that would be great
Regards
Gareth_L
