The client application uses this service to set up a call on behalf of a station extension
(calling party) to an on- or off-DBS endpoint (
calledDevice
).
All trunk types are supported as facilities for reaching called endpoints for outbound
csta-
MakeCall
calls. The only call progress feedback that is reported as an event to the applica-
tion via Monitor Services is Networked Reached.
For the originator to place the call, the
callingDevice
(digital extension) must have an
available appearance for call origination and must not be in the talking (active) state on
any appearances. The originator is allowed to have a call(s) on hold or alerting at the
device.
The originator may go off-hook or turn the speaker on and receive dial tone first, then
issue the Make Call Service request for that station. The switch will originate the call on
the same callID to establish the call.
If the originator is off-hook busy, the call can not be placed and the request is denied. If the
originator is unable to originate for other reasons (see
universalFailure
), the switch
denies the request.
