2.24 The Voice Processing Unit begins the message transfer process by transmitting the mes-
sage type (new or reply), message length (if available), the originating mailbox, and the desti-
nation mailbox. If the remote system responds with an unsuccessful acknowledgment, the
Voice Processing Unit returns the message. If the Voice Processing Unit has not reached the
per-call message limit (nine messages per standard AMIS-Analog), and there are more mes-
sages, it continues with the next message. Otherwise, it ends the AMIS session and discon-
nects.
Incoming Calls
2.25 Call Routing Announcement applications are the only applications that can receive and
process incoming AMIS calls. If any other application answers an incoming AMIS call, the
application eventually times out. If a Call Routing Announcement application answers an
incoming AMIS call, the application's Accept Network Calls flag must be enabled for it to pro-
cess the AMIS call. If it is not enabled, the call times out.
2.26 After the Voice Processing Unit sets up the AMIS call, it performs the following tests to
see if it can deliver the message:
•
Checks to see if there is enough disk space to receive the message.
•
Checks to see if the destination mailbox exists.
•
Checks to see if the destination mailbox is full.
2.27 If any of the tests fail, the Voice Processing Unit sends the appropriate response to the
originating system and then waits for the next message. If all the tests pass, it begins recording
the message. The Voice Processing Unit continues recording the message until it detects
DTMF tones or at least ten seconds of silence, or until the recording exceeds the maximum
message length. If it detects ten seconds of silence or if the recording exceeds the time limit, it
disconnects. If it detects DTMF tones during the recording, and the DTMF tones are not the
End Message signal, then it ignores the tones and continues recording.
2.28 When the Voice Processing Unit receives the End Message frame, it delivers the mes-
sage to the destination mailbox and waits for the next frame. If the next frame is the End Ses-
sion frame, it disconnects. If the next frame is another Message Information frame, it verifies
that it has not received the maximum number of messages during this call. If it has, it sends an
error response and disconnects. If it has not, it begins receiving the next message.
AMIS-Analog Protocol Limitations
2.29 These limits are enforced when the Voice Processing Unit places calls to or receives
calls from another Voice Processing Unit or a non-Inter-Tel Voice Mail system that supports
AMIS-Analog.
•
Maximum of nine messages per call.
•
Maximum of one recipient per call. If the same message is to be delivered to multiple
mailboxes, the message must actually be transmitted multiple times.
•
Maximum message length is eight minutes.
•
Certified delivery of messages is not supported.
•
Priority message indication is not supported.
•
Private message indication is not supported.
