Your voicemail PIN number cannot contain any of the following patterns:
- Any sequential string of numbers. (1234, 5678, 3456, etc.)
- Any portion of your phone number. (If your phone number was 555-2641 you could not use 2641, 5264, 5526, etc.)
- The same number repeated. (1111, 2222, 3333, etc.)
These restrictions are in place to protect the integrity and privacy of your TekTalk service as these sequences would leave your account very vulnerable to a brute force attack.
