How to protect your business from PABX Fraud
Here are just some of the ways that you, personally, can protect your system:
· Regularly change your personal and group voicemail box passcodes
· Do not use default passcodes such as ‘0000’ or ‘1234’
· Block all international calls access unless absolutely necessary
· Block international call access to countries that you don’t usually dial
· Ensure your PABX admin access unit is kept in a secure location
· Look for heavy call volumes at nights or on weekends and public holidays
· Review system call records for discrepancies and unusual use
Ways in which a technician can assist to increase the security of your telephone system:
· Disable any call forwarding or outbound call ability from your voicemail ports
· Cancel any unused voicemail boxes
· Update the passcode for voicemail administration access
· Restrict the ‘after hours’ outgoing call access
· Disable DISA access unless absolutely necessary
