Hi Bjc47, thank you for coming back to us with some additional information.
Sincerest apologies for your experience whilst trying to get this missing Caller ID issue resolved!
Would you also be able to confirm the make and model of handsets you are currently using, and having the issue with?
Following this we need to identify if the issue is with the handset, provisioning of your account, or at the exchange.
In terms of provisioning - as turning the feature off and back on virtually does not seem to have resolved the problem it may be the case you need a technician to investigate further. As soon as we have confirmation of the make/model handset you are having the issue with, we will be able to offer further support.
Thank you for your patience and cooperation!
All the best.
Molly
