@FIX_CID The huge problem with your request is the spam and scam callers already show the same fake number they are calling from in both the name and number. It's one big indicator an incoming call is spam.
The problem is all calls from Bell cell phones show up as "anonymous". On iPhones we don't get both number and name fields on incoming calls, so almost every call I receive says anonymous. There should be so way to correct this.
Complain to Apple for not showing both lines of information. All iPhones work that way.
It is my opinion that TELUS should not change the CName information. If CNAME info is not provided or available then TELUS should not add this field to the call info. The receiving device can decide how to display the missing info, such as "unknown"
