Configuring MultiVoice
Using authentication
When you require PIN authentication
If you configure PIN authentication, the MultiVoice Access Manager processes calls as
follows:
1 The caller dials the local MultiVoice Gateway.
2 The local MultiVoice Gateway presents three quick tones to the caller.
3 The caller enters a PIN, followed by the pound sign (#).
If the pound sign is omitted, the MultiVoice Gateway sends the user’s input after a few
seconds.
4 The caller enters the destination phone number, followed by the pound sign (#).
5 The local MultiVoice Gateway initiates a session with the Gatekeeper running the
MultiVoice Access Manager and passes the PIN and destination phone number to it.
If the caller enters an incorrect PIN the MultiVoice Gateway prompts for a new PIN by
sending the caller a single long tone followed by three quick tones. The MultiVoice
Gateway allows three incorrect PINs before disconnecting the caller.
6 If the caller enters a correct PIN the MultiVoice Access Manager selects the IP address of
the destination MultiVoice Gateway, on the basis of configured coverage areas, and sends
it to the local MultiVoice Gateway.
If MVAM finds no MultiVoice Gateway with a coverage area that supports the called
number, the local MultiVoice Gateway disconnects the call.
7 The local MultiVoice Gateway initiates a session with the destination MultiVoice
Gateway.
8 The destination MultiVoice Gateway initiates a session with the MVAM to determine if it
approved the call. The MultiVoice Access Manager acknowledges the call request from
the distant Gateway.
If the MVAM rejects the call request, the destination MultiVoice Gateway disconnects the
call.
9 The destination MultiVoice Gateway dials the destination phone number to complete the
connection.
Note: If you require PIN authentication, you must set the Ethernet > Mod Config > VOIP
Options > VPN Mode to No on all registered MultiVoice Gateways. Otherwise, callers will not
be prompted for their PINs, and their calls will fail.
When callers dial into the MultiVoice Gateway, it presents them either with a dial tone or with
prompts indicating that MultiVoice Access Manager requires PIN authentication.
If the caller does not press the pound sign after entering a string of digits, the MultiVoice
Gateway waits for a timer to expire, then sends the string to the Gatekeeper running the
MultiVoice Access Manager. Initially set to 16 seconds, the timer starts running when the
caller enters the first digit, but restarts after each subsequent digit. However, each restart
decrements the timer by half a second, up to 14.5 seconds. If the caller enters 30 or more digits,
the MultiVoice Gateway waits two seconds before sending the string.
If the call is not established within several seconds, the local MultiVoice Gateway sends a
tick-tock sound to the caller to indicate that the call is still proceeding.
