Secure PBX

A widely reported fraud scenario is the case of a malicious user detecting the address of a company’s PBX gateway and accessing that PBX directly. Once the attacker has managed to have access to the PBX the attacker can start making calls and even selling telephony minutes through that PBX with the costs incurred upon the owner of the PBX.
