Point-to-point video calls
Touch tones (DTMF) in a call
In a call you may be prompted to
submit numbers to be able to reach
an extension or otherwise enter into
something (for example with a PIN-
code).
To be able to submit this you will
need a keypad on the Touch screen.
The technical term used with this is
DTMF (Dual Tone Multi-Frequency),
which describes what actually takes
place.
About DTMF
In a call, tap Touch
