blocked for each COS.
[Programming Example]
: Block
Explanation:
a) COS 1 extensions can make calls to all extensions.
b) COS 2 extensions can make calls to COS 1 destinations only. (COS 2 extensions cannot make
calls to COS 2 destinations.)
c) COS 3 extensions can make calls to COS 3 destinations only.
Conditions
• Restricted extension numbers cannot be used as the parameter of a feature setting (e.g., FWD)
• All extensions can make an Operator Call (→ 2.2.5 Operator Features) regardless of Internal Call Block.
• This feature can also restrict calling a doorphone from an extension on the basis of the COSs assigned
to the extension and doorphone port. (→ 1.15.1 Doorphone Call)
