Voicemail PIN policy: prevent '0000' as a PIN.
Default PINs (0000, 1234, extension itself) are the first vector for toll fraud. Force a PIN change on first use and block trivial codes.
Try this first
- 1PBX setting: force PIN change on first login.
- 2Block trivial PINs (000000, 123456, extension digits).
- 3Disable voicemail for extensions unused for X months.
- 4External voicemail checking off by default, only on for who needs it.
