User permissions
Disallow security-risk permissions for all users except those individuals who really need them.
You can change permissions for individual users by editing the user account.
• Security-risk permissions which should be disallowed are:
• Place external calls when logged on via a trunk (under the Standard permission group)
• Log on via trunk (Standard)
• Log on via IP trunk (Standard)
• Log on via station (Standard)
• Forward or route calls to external numbers (Standard)
• Return calls when logged on via a trunk (Standard)
• Select a specific trunk for outbound call (Administration)
Setting up dialing restrictions
A good way to prevent unauthorized outbound calling is to place restrictions on users' dialing
permissions. You can change permissions for individual users by editing the user account.
Some dialing restrictions to consider:
• Disallow access to any number dialed during toll fraud. To find a list of numbers, search
your call logs for frequent calls to international locations.
• Disallow dialing 011 and 00 to block all international calls (00 dials the international
operator).
To permit some international calls you can do the following:
• Enable 011 for those individuals who are authorized to make international calls.
Those individuals can then dial any country.
• Enable country codes for those foreign countries that are appropriate for users to
call. To do so, enable 011xxx where xxx is the desired country code.
