the hotline number. No other users can share the phone line. Note that
universal call blocking disables triggering via a long DTMF tone.

1. Take your phone off-hook
2. Enter # * 2 1
3. Press # #
4. Listen for two confirmation beeps
5. Place your phone on-hook

Advanced Hotline Number Programming
You can program a hotline number that is a sequence of numbers, separated
by timed pauses and other events, such as prompts for computer tones or
DTMF tones. You can do this by programming a dialer string. A dialer string
is made up of a series of instructions and numbers. Instructions include one
that tells the dialer to wait for a certain amount of time, and others that tell
the dialer to wait for a computer tone, for voice, or for DTMF. Numbers can be
phone numbers, PINs, or other codes that you want the dialer to dial.
Dialer strings can be too long to program all at once by hand. Therefore, you
enter dialer strings one instruction or number at a time. There are separate
commands to start a dialer string, and to add to a dialer string that has
already been started.
To start a dialer string, do the following:
1. Take your phone off-hook
2. Press # 0 #
3. Enter the first Instruction or Number
(Instructions are listed below. A Number is from one to 92 DTMF digits.
See details below.)
4. Press # #
5. Listen for two confirmation beeps
6. Place your phone on-hook
To continue a dialer string, do the following:
1. Take your phone off-hook
2. Press # 1 #
3. Enter the second or third, etc., Instruction or Number
