Hi @rnmh1964,
Thank you for your post and welcome back to our community forums. We're here to help.
I'm really sorry to hear you've been facing some issues with your Caller ID function recently, and that connecting a different handset also hasn't helped to alleviate the issue. I've checked our systems on our end, and I'm unable to detect any issues on the line that would explain this problem for you.
Are you facing any issues with your broadband (wired or wireless/Wi-Fi) and other devices connected to it, or is it only the Caller ID function?
Thanks,
