DETAILED DESCRIPTION OF SERVICES
5.1
General description of opening greeting service
Four working
modes are available with T11/T12. T11 accepts incoming call, plays the opening greeting
message associated to current mode for different times and after this, caller can interact with the system.
T11/T12 will therefore perform one of the following operations:
•
It goes to “on hold” mode with the closing greeting, “End of the Service”
•
It connects caller and operator
•
It connects caller with the desired extension after caller’s DTMF digit selection
•
It connects caller with the desired extension after caller’s DTMF extension selection
•
It allows recording message in mailbox
The call transfer to a PBX’s extension is performed with the following operations:
•
While caller is listening to music on hold, the unit calls the desired extension
•
It detects if the extension is busy (tone recognition)
•
If free, T11/T12 connects called and caller, releases the line and it’s ready to accept a new call.
•
If busy, it transfers the call to the operator console
No control on possible busy state of the operator is performed: the PBX must be able to queue incoming
calls. After the extension’s number selection, the unit plays “Incoming call” message in order to notify called
person.
5.2
Automated Attendant service: a detailed example
The unit’s operating mode is described as follows:
•
It accepts incoming call and answers
•
It plays an opening greeting to callers (one or more times)
•
If it receives a DTMF tone, it breaks message playback and sets a 3 seconds service delay
•
When delay is expired, it verifies if only a single digit or a complete selection (max 3 digit) has been
received
•
If only a single digit arrives, it verifies if the digit is associated to any extension number
•
If it doesn’t find any association, it plays “Invalid selection” message
•
If it find the associated extension, it puts on hold the caller and calls the extension required
•
If it detects busy, it transfers the call to operator and when the call’s transfer is finished, it releases
the line
•
If it receives more than one DTMF digit, it puts on hold the caller and dials the number received. No
control is performed before dialing this number
•
If it receives a busy tone, it sends the call to the operator and it releases the line after dialing
•
If it does not receive any digit, T11/T12 dials the number programmed as operator and releases the
line
5.3
Automated Attendant and Answering System service: a detailed example
The unit’s operating mode is described as follows:
•
After the answer, when opening greeting has finished, the unit will announce “Press 0 to leave a
message” (parameter 30=0), if parameter 30=1 then the unit will accept the message with no
condition
•
If the caller does not dial digit “0”, T11/T12 goes on with normal operational mode
•
If caller dials “0” (or parameter 30=1) the unit will announce “Please leave a message after the tone”
and plays one second beep
•
Caller takes a message of customized length (parameter 29), the unit releases the line later.
CAUTION
:
if system storage is full, the “take a message” announce will not played as far as the user deletes
old messages in mailbox.
