9.3 Time Control

Several time groups can be configured in the OpenCom 100 / Aastra 800.

Depending on the activated time group, incoming calls are signalled on different

terminals. It is possible to automatically change between these time groups,

manually.

You can only program this function if the system administrator has activated the

“Time control” authorisation for your user group.

This feature cannot be used with a SIP terminal.
