Universal Network-Level Call Blocking

Nexicom is implementing Universal Network-Level Call Block (UNCB).

UNCB will help to protect you against certain types of unsolicited calls by blocking calls when Call Display information is clearly inaccurate.

What type of calls are blocked?

  • Calls with unassigned North American area codes (for example, 000-000-0000, 111-111-1111, 123-456-7890, etc).
  • North American calls that have less than 10 digits (for example, 0000, 1234, 12345, etc). Note that this does not include 310- calls.
  • North American calls that have more than 10 digits (for example, 705-775-6394-1234). Note: This does not include long distance calls that begin with the number 1 (for example, 1-905-837-1111 or 1-800-595-1234, etc).
  • Calls originating from international countries containing more than 15 digits (for example, 11-123-222-222-111-111, etc).

These phone numbers often include various types of spam, unsolicited, unwanted phone calls, such as fake marketing (e.g. free security system offers), and they usually originate from telemarketers who are not registered with the National Do Not Call List (NDNCL).

These numbers can appear as a string of numbers, a random number, or the number of a person, company, or even a government entity. Telemarkers making sales calls to customers in Canada have an obligation to accurately identify themselves. Those using technology to purposefully change their Call Display with inaccurate, fake, or misleading information violate this requirement.

Universal Network-Level Call Block (UNCB) should help reduce the number of unsolicited calls that you receive, although it will not block all unsolicited calls.

Wightman will be implementing Universal Network-Level Call Block (UNCB) Fall 2019. You can read more about the CRTC policy on Network-Level Call Blocking here.
