Technical Tips - Lock Thieves Out of Your Customer's Phone System
Tell your customers about these important steps!
Why do they do it?
People like free things. A free phone call doesn't exist. Whether
it's a hacked payphone or a cheap call to the home country via a
series of PABX's and trunks across the world, someone pays. Free
phone calls are theft from someone else.
Change Codes Frequently
Change the authorization and voice mail passwords and security codes
as often as is appropriate for the user community. Delete codes of
former employees. Change the passwords for PABX system and voice mail
administration terminals regularly. Also, change system passwords
when key personnel with password knowledge leave your organization.
Restrict International Calls
International locations are the major destination for toll fraud
calls. Restrict international and interstate calls if authorized
users do not normally place calls to these locations. If users do
place calls to international locations, allow only the area codes and
country codes they require. Also: consider time of day shutdowns
(individual over-ride codes can by issued as required).
Secure Access Codes and Passwords
Don't allow employees to post access codes and passwords in plain
view. Look under the terminal keyboards, etc. for “the usual hiding
places” – crooks will.
