8.6.2.1.10 Hold Call
The Escape service allows for the installation of private services not defined in the ECMA
CSTA protocol. See Private Services for a description of private services defined for the
Alcatel-Lucent OmniPCX Office Communication Server.
The Hold Call service places an existing connection on hold. The behavior is identical to a
manual Hold. The service supports multiline and monoline devices.
8.6.2.1.11 Make Call
The Make Call service creates a CSTA call between two devices.
Details specific to the Alcatel-Lucent OmniPCX Office Communication Server for the Make
Call service are:
- The Make call service is allowed if the originating device is in the idle state, or has one call
initiated, or is in the disconnected state (the remote party has cleared the connection).
- The system does not check the validity of the called device's number or state.
- If the device supports on-hook dialing, the service can be configured to start calls
immediately without prompting.
- If no called number is provided, the device goes into hands-free or dialing mode.
Make Call sequence of events when device is in the idle state:
1. The originating device is in the idle state.
2. The service rings the originating device (local ringing). The service is unaware of the
device's active features (for example, forwarded, monitored, do not disturb). If the device
has a display, it displays "Automatic call".
3. The user can:
• refuse the service using soft keys, the fixed release button, or, if the device is not in
auto-answering mode, by waiting for the time-out (20 seconds).
• accept the service by picking up, using soft keys, the hands-free button, or, if the
device is in auto-answering mode, waiting for the time-out (5 seconds).
Note 1:
The auto-answering mode can be enabled only for sets having the broadcasting facility. It is not
enabled for analog or GAP sets.
4. In the case where:
• the service is accepted, the application dials for the user. The subsequent call progress
information (tones, display, LED s and soft keys) is identical to that of a manual call.
• the service is refused, the device goes into the idle state. The initiated connection is
cleared.
Note 2:
The Make Call prompt cannot be overloaded by another call.
Make Call sequence of events when device is in initiated state:
1. The originating device has one call in the initiated state.
2. The application immediately launches the call using the initiated connection and dialing for
the user. The subsequent call progress information (tones, display, LEDs and soft keys) is
identical to that of a manual call.
