Call Blocking

_

CRTC-mandated Universal Call Blocking

The Canadian Radio-Television and Telecommunications Commission’s (CRTC) has mandated that telecommunications companies implement measures to protect Canadian consumers against unsolicited and fraudulent calls.

To comply, other carriers will start implementing Universal Call Blocking as early as November 2019. 
TELUS will not be implementing Universal Call Blocking
 as we provide a call filtering solution that protects our consumer customers from suspected nuisance calls.

Impacts to business customers

While TELUS expects that most calls will go through without any issue, there may be times when calls will be blocked, such as:

  • Unassigned North American area codes (e.g. 005-143-4561, 000-000-0000, or 123-456-7890)

  • North American calls that have more than 10 digits (e.g. 905-243-4561-1234). This does not include long distance calls that begin with the number 1 (e.g. 1-800-223-1234 or 1-613-245-1234)

  • Calls originating internationally with more than 15 digits (e.g. 33-131-234-456-234 or 44-131-234-456-234)

Please note that 9-1-1 calls will not be blocked regardless of the calling number.
 Additionally, this does not impact numbers that are toll-free, listed as private, or have a valid calling number as outlined by the North American and International numbering plans.


Next steps

As a result, it may be necessary to reconfigure your equipment to ensure that all telephone numbers conform with the North American and International numbering plans (using active, assigned numbering plans) in order to avoid having your calls blocked.

The simplest way to determine if you have a non-compliant number is to call a TELUS mobile device and view the Call Display, or to see what your telephone number is displaying, call our toll-free, automated support number 1-855-925-5006.
