Thanks for posting your inquiry to the Rogers Community! This is a very unique question as we're normally asked about incoming calls rather than outgoing ones.
I'm afraid there is no such thing as a local calls "blocker". Here's a list of the Calling Features your can get with Rogers Home Phone:
For more information, or if you want to know exactly what each feature includes, check out the What Home Phone Calling Features are there? article. 😉
Hope this helps!
This is a good thing to have with a parent that has dementia and calls people numerous times without remembering.... once the receiving person expresses that they wish for the calls to stop it would be great to be able to block an outgoing number from being called.
