•
Internal Call Block also prohibits certain features, such as Walking Extension and Walking COS, from
being performed between certain extensions.
•
Any extension can make an Operator Call regardless of the Internal Call Block setting of its COS. (→
14.1.7 Operator Features)
•
Because each doorphone port is assigned a COS, the Internal Call Block feature can restrict certain
extensions from calling certain doorphones. (→ 5.1.15 Doorphone Call)
