Query a voice server, a voice mailbox, a
messaging service, etc. (DTMF tones)
Some phone services (such as phone answering machines and pagers) require your phone to
transmit DTMF tones (Dual Tone MultiFrequency), also known as "touch tones". These are
used to communicate passwords, callback numbers, caller choices, and so on.
You can send DTMF tones at any time during a call by pressing any of the keys
and .
You can also append a DTMF sequence to a phone number before dialling it (or storing it in the
Names list). The phone number and the DTMF part must be separated by a wait character.
Pause and wait characters
To obtain a pause or wait character, press and hold
p
for a pause. The phone always interprets the first pause character 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.

Any subsequent pause character is an ordinary pause that generates a delay of 2.5 seconds.
