Protective Actions for Avaya and Mitel Systems to Help Stop Toll Fraud

You’re one step closer to mitigating the financial and security risks of Toll Fraud for your company. Over 90% of Toll Fraud attacks occur on weekends and bank holidays. We can’t eliminate the potential for Toll Fraud but taking these steps and requesting a Fraud Risk Assessment will help.

Steps You Can Take Right Now to Mitigate Against Toll Fraud

  1. Ensure that a ‘strong’ password is used on ALL your SIP devices (iPad, soft phone, mobile client, SIP phones, etc.)– not the extension number or an easy to ‘guess’ password.
  2. Only use SIP devices if both the phone system and the SIP device have a mechanism to secure SIP (e.g. Digest Authentication).
  3. Never expose SIP phones (softphones or physical phones) to the Internet without encryption or a VPN.  Talk to Britannic if you need advice on how to secure remote devices.
  4. Ensure that your individual voicemail users have changed their passwords.
  5. Consider changing to 6-digit passwords, if not 6 already.
