Important Notice Regarding Universal Call Blocking

In an effort to reduce unwanted nuisance calls, we will implement Universal Call Blocking (as required by the CRTC) beginning November 2019. This will block incoming calls that contain telephone numbers that do not comply with North American or International numbering plans e.g. 00000.

FAQ’s about Universal Call Blocking

 

What is Universal Call Blocking?

Universal Call Blocking is a CRTC mandate (CRTC decision 2018-484) to block all incoming voice calls that have malformed calling line ID information. This applies to all Canadian service providers. Malformed calling line ID information contains telephone numbers that do not comply with North American or International numbering plans.


How will Universal Call Blocking affect me?

Universal Call Blocking will prevent you from receiving calls with calling line IDs that have malformed numbers.


How does Universal Call Blocking work?

Any incoming call with a malformed calling line ID will likely be blocked by the destination party’s service provider.


How can I tell if a number is Malformed?

Generally, any number that does not comply with the North American Numbering Plan or international standards will be blocked. 000 000-0000, 111 111-1111 or numbers with more than 15 digits are examples of non-compliant numbers.


Can I opt out of Universal Call Blocking?

No, Universal Call Blocking is a CRTC- mandated service that applies to all customers.


Will Universal Call Blocking work on and device?

Yes, Universal Call Blocking is a network level solution that is applied to all incoming voice calls for wireless, IP and landline phones.


Will I be charged for this?

No, the Universal Call Blocking is free of charge.


Why am I still receiving spam calls from numbers that appear legitimate?

Universal Call Blocking only blocks calls with malformed calling line IDs. Unfortunately this may not stop all spam calls.


If I  use extension dialing for intra-office communication, will it be impacted by Universal Call Blocking?

No, Universal Call Blocking will not scan any intra-office calls. Extension dialing within the office network will not be impacted.


After the rollout of Universal Call Blocking, are customers expected to make any changes in their handsets, wireline phone instruments or IP phones?

No, Universal Call Blocking is applied at network level, so you are not required to make any changes in settings on their end. If you have a programmable calling line ID, you must ensure that a compliant calling line ID is displayed – otherwise outgoing calls may be blocked by other Canadian voice service providers.


Who can alter their caller ID?

If you have a phone system that is capable of modifying the outgoing Caller ID (through a physical PBX or in the cloud), then calls with a malformed Caller ID may be blocked by universal call blocking. It is important that you use a number compliant with the North American Numbering Plan, e.g. your 10-digit main telephone number to avoid any service interruption.
