Conditions
• Walking COS
The extension user can make a toll call at other lower level COS extensions (toll / outward
restricted) by employing his own higher level COS temporarily.
• Switching COS
Two different levels of COS, Primary COS and Secondary COS, are assigned to all
extensions. However, either one of them is valid at a time. The Manager and the Operators
can change the COS level of any extension including their own.
