Gateway Calls

Wrong Destination Number

The number of re-dial attempts is controlled by the WRONG_NUMBER_DIAL_RETRIES system flag.

The default number of redial attempts is 3. To modify the number of redial attempts, manually add the flag to system.cfg and set its value to the number of redial attempts required.

The flag value range is 0-5. A flag value of 0 means that no redials are attempted. For more information about system flags see .

Redial attempts follow the same order as defined in the Gateway Profile: H.323, followed by SIP, followed by ISDN. For more information about Gateway Profiles and Gateway Dial out Protocols see Defining the Gateway Profile.

Redial on Wrong Number is activated if a Gateway Call fails, for all defined protocols, for any reason or combination of reasons listed in the following table.

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.
