Conversation State
Send a DTMF Signal
When DTMF function has been set, the numerical key,
#
key and
*
key pressed
will be transmitted to the recipient as DTMF signal in a communication. Setting for
disabling DTMF during a conversation can prevent undesired and accidental touch of keys.
If it is disabled, extensions can not be dialed.
For example, when you dialed “1861” to inquire the balance or recharge, the
pressed selection keys and password of the recharging card can not be sent to the
counterpart if you disable DTMF at that time, and 1861 would continue to give
instructions for no keypad operation detected.
Handsfree
There is a prompt at the lower right corner of the screen during a call. Press the
right soft key once to enable the handsfree function, Press the right soft key again
to resume to the normal call.
