During the 403/780 area code split in 1999, Telus decided to set up a series of test numbers called Alberta Terminating Test Lines in the 403 and 780 area codes. Since the split affected millions of landline/cellular customers, Telus thought that permissive phone numbers would be the best way to keep the information flowing between employees. There were two main types of Terminating Test Lines created during the 403/780 area code split: Lines to leave messages on other numbers, and numbers to receive messages on (which were similar to messageboards). The test lines set up in the messageboard format were used to wide dissemination of information relevant to a large group. Technicians could call up the messageboard lines and receive up-to-date information regarding the area code split in a pre-recorded format. The other type of test lines, the lines to leave messages on other numbers, were used gave Telus technicians the ability to call up a private number and leave detailed messages regarding any technical issues that may have arisen with 780 to 403 (and 403 to 780) long distance call routing.
