Incoming Calls
Parallel Ringing
Note: This feature is only available in newer versions of the
exchange.
The Parallel Ringing feature makes it possible for an incoming call
to ring several phones simultaneously and for the call to be
answered on any of the phones. The main advantage of this feature
is that you do not risk losing any calls.
The feature requires all the phones involved to be defined in a
Parallel Ringing list, which must be configured and initiated by
your system administrator. Because only calls to a main extension
will be distributed among the phones in the list, this main extension
also needs to be defined.
A call to a specific extension will not be distributed to other phones
in the list, and will only ring that specific extension's phone.
Parallell Ringing can be temporarily disabled by the phone user
using the feature “Internal Follow-me”. See also section “ Internal
Follow-me ” on page 29.
Note:
If an extension part of a parallel ringing list tries to activate/
deactivate one of the features below, the procedure is only
performed on the main directory number not on the
extensions own number.
- Call diversion for non-generic extension
- Do not disturb
- External Follow-me
- Follow-me
- General Cancellation
- Individual Repeated Distribution or Personal Number
- Message Diversion

list only, follow the procedure for disabling the feature from this
