The following overview shows the switching functions which can be 

accessed in ringing status. The desired called party is called in the 

ringing status but has not yet answered the call.

You can use this function to save a callback request if the internal par-

ty called is conducting a call, does not answer or switched off his/her 

mobile telephone.

The callback is performed by the telephone system as soon as the 

called party performs one of the following tasks:

• Ends  the  call

• Activates the mobile telephone and conducts a call

• Performs the callbacks saved in the telephone system’s mailbox

The callback is deleted if you do not answer it within four rings.

You can use this function to save a phone number if the internal party 

called is conducting a call or does not answer.
