 Options during a call

tions which are only available during a call.

rent circumstances.
Note:
Some supplementary services will be unavail-
able during satellite calls to other Thuraya
mobile phones.

Sending DTMF signals during a call
During a call you can send DTMF (Dual Tone
Multi Frequency) signals, even if sending of
DTMF tones is not set in advance (see page

By this you can send DTMF tones during a
call to a service which accepts only DTMF
tones, e.g. in order to enter access codes for
listening to an answering machine. After the
function is switched on, a DTMF tone is sent
with each key press.
The function has to be called for each DTMF
tone sequence to be sent.
To send DTMF tones during an active call:

a service that requires DTMF tones

ting down the connection.
