APPENDIX B – ADDITIONAL SERVICES
1. Call Waiting Notification
The service uses a definite signal to notify user about a new incoming call when the line is already busy
with another call.
Having received the signal, the user may decide to pick up the waiting call.
The service can be chosen in the menu with user port settings in the VoIP/SIP Advanced Setting tab (see
section 4.4.2 The The SIP Advanced Setting Submenu. SIP Advanced Settings) by setting the Call waiting flag.
When you receive the new call notification while you are already talking, press R to hold the current call
and take the waiting one. All further pressing of the R button will be processed according to the algorithms
described in sections 2 Call Transfer and 3 Conference.
– R – a flash release.
2. Call Transfer
The Calltransfer service allows temporary interruption of connection with active subscriber (subscriber A),
connection to another subscriber (subscriber C), and transfer of the call with disconnection of subscriber B (the
subscriber providing the service).
The service description:
While being connected to the subscriber A, hold the call by pressing the flash release (R), wait for the
"station response" signal, and dial the subscriber C. When the subscriber C answers your call, hang up.
3. Conference
Conference is a service allowing three and more subscribers to have shared phone conversation.
The service description:
While being connected to the subscriber A, hold the call by pressing the flash release (R), wait for the
"station response" signal, and dial the subscriber C. When the subscriber C answers your call, press R to switch
to the conference mode.
The subscriber who starts the conference is a chairperson; the rest two subscribers are participants. When
the chairperson presses flash release in the conference mode, the last called subscriber is disconnected. A
participant may put on hold other participants.
The conference ends when the chairperson hangs up; the rest two participants will receive the release
signal in this case. If a participant leaves the conference, the chairperson and another participant are switched
to a normal two-party call.
4. Message Waiting Indication (MWI) – Notification about Voice Mail
If a voice message is left on server for a subscriber, the service allows the subscriber to be timely notified
about the message. When the MWI service is enabled and there is an new message on server, the subscriber will
hear a discontinuous buzzer when he picks up the phone.
In order to enable the MWI service, set the flag in the MWI field of the corresponding port on the VoIP/SIP
Advanced Setting tab (see section 4.4.2 The SIP Advanced Setting Submenu. SIP Advanced Settings).
