Some telephone services(such as telephone answering machine and
pager) require your telephone to transmit DTMF tones(Dual Tone Multi-
Frequency), also known as “touch tones”. These are used to communicate
passwords, call back numbers, and so on.
Wait Characters
To obtain a wait character, press and hold . The display shows P for
a wait. The phone always interprets the P as a wait character.
When you dial a number containing a wait character, your phone dials the
first part(the phone number) and then waits for the call to be connected
before sending the rest of the digits as DTMF tones.
