What are restriction/permission lists and codes?
Introduction
Restriction/permission lists are an important part of preventing
users and callers from abusing your Meridian Mail system.
Definition:
restriction/permission
list
A restriction/permission list is a group (or set) of restriction
codes and permission dialing codes that can be applied to
Meridian Mail features or services that are capable of placing
outcalls.
Up to 80 lists can be created, but each list must have a unique
name. Each list can have up to 30 restriction codes and up to 30
permission codes. Once a list is defined, it can be applied to a
number of Meridian Mail features.
Definition:
restriction code
A restriction code is a dialing code that Meridian Mail is not
permitted to dial. When Meridian Mail is passed a number that
begins with a restricted code, the call is blocked.
Restriction codes can be up to 20 digits in length.
Example 1
Your local dialing prefix is 9, your long distance dialing prefix
is 91, and your international dialing prefix is 9011. You want to
restrict all off-switch dialing. The restriction code is 9.
Example 2
Your long distance dialing prefix is 91 and you want to restrict
calls to the 801 area code. The resulting restriction code is
91801.
Definition:
permission code
A permission code is a dialing code that Meridian Mail is
permitted to dial. These are usually exceptions to the restriction
“rules.”
Permission codes can be up to 20 digits in length.
