Canadian universal call blocking


Jack Reiland


What's happening? 

In keeping with the recently mandated call blocking measures by the Canadian Radio-television and Telecommunications Commission (CRTC), and in an effort to help customers protect against unsolicited and illegitimate calls, Bandwidth and its partners have implemented network-level call blocking for all of its numbers in Canada.

What do I need to know?

Canadian network-level call blocking is designed to prohibit all calls that come into our Canadian network where the caller identification of the Originating phone number:

  • Exceeds 15 digits
  • Is malformed and doesn't conform to a dialable number for calls initiated under the North American Numbering Plan (e.g. 000-000-0000, 000-111-0000, 222-022-2222) 

What do I need to do?

The CRTC has required Canadian service providers to implement these call blocking measures uniformly to ensure consistent call blocking practices by all providers. We recommend that you notify your network team and end-users so they can make any necessary changes to your particular service offerings to ensure that valid calls aren't inappropriately blocked because they're utilizing non-conforming numbering formats or caller identification information.
