The cost of such calls will be billed to the owner/renter of the PBX.
To protect the PBX from this kind of fraudulent use, we strongly recommend:
a. Enabling DISA security (Trunk Security or All Security).
b. Keeping your passwords (verification code PIN/extension PIN) secret.
c. Selecting complex, random PINs that cannot be easily guessed.
d. Changing PINs regularly.
