Five Success Tips when using the Voice Prompt
 "*" shifts down to the next menu option and "#" returns to the main menu
 "9" functions as the ENTER key in many cases to confirm or toggle an option

All entered digit sequences have known lengths - 2 digits for menu option and 12 digits for IP
address. For IP address, add 0 before the digits if the digits are less than 3 (i.e. - 192.168.0.26
should be key in like 192168000026. No decimal is needed).

Key entry cannot be deleted but the phone may prompt error once it is detected.
