The user receives the Redial on Wrong Number IVR message: “Incorrect destination. Please
enter the destination number”.
If all the redial attempts fail the user receives the Disconnect on Wrong Number IVR
message: “Destination could not be reached; call is disconnected”.
Gateway Re-dial is not activated if the reason for call failure is Busy or No Answer, for any
of the defined protocols.

Wrong Destination Number Time-out

•A time-out counter is started when the Redial on Wrong Number message is played. If the
user does not enter another destination number within the time-out period it is
considered a failed dial out attempt.
•The Redial on Wrong Number message and time-out are repeated according to the value
of the WRONG_NUMBER_DIAL_RETRIES System Flag. If there is no input from the
user, after completing the retries, the user receives the Disconnect on Wrong Number IVR
message: “Incorrect destination number” followed by the Reorder Tone.

Disconnect on Busy

As in previous versions, redialing of calls to busy destination numbers can be selected. The
number of redial attempts is dependent on the NUMBER_OF_REDIAL System Flag, the
default value is 3. For more information see "Defining New Profiles” on page 2-18.
In previous versions, if all retry attempts failed, there were no further call attempts with no
notification.
When using this version, if all retry attempts fail, the user receives the Disconnect on Busy
message in the form of Busy Tone. The call is then disconnected.

Disconnect on No Answer

In previous versions, if a call failed due to no answer at the destination, the call was
disconnected with no notification.
When using this version, if all retry attempts fail, the user receives the Disconnect on No
Answer message in the form of Reorder Tone. The call is then disconnected.
