Programming the Ringing Assignment
Each external telephone number connected to the Opera 4 IP may be programmed to ring a
different user or set of users on incoming calls. The SIP trunk assignment is done on the
‘Ringing assignment’ page in the section ‘External Numbers’. The ISDN ringing assignment is
done on the ‘Ringing Assignment’ page under ‘External Numbers’. The analogue line
assignment is done on the ‘ Analogue Ringing Assignment’ page under PSTN Analogue Trunks.
The ringing assignment may be changed for different times of the day. By default, three ringing
modes are defined, ’Day ringing’ and ‘Night ringing’ and Operator Mode and there are two
additional modes that can be defined by the user.
By default, all external lines are programmed to ring the first IP user, 11, of the Opera 4 IP. This
user, in the default configuration, is defined as sole member of the operator group, group 9.
This ringing assignment can be changed by typing the users or groups or Auto-Attendant
message to be called when an incoming call arrives on a particular line, as shown below and
pressing the SAVE button.
You may proceed to program another ringing mode by clicking on the link below the table on the
left.
