Dialing During a Connected Call

When calling interactive teleservices, such as phone banks, you need to
use Dual Tone Multi Frequency (DTMF) signals. If the phone exchange
is not already programmed to automatically convert entered digits into
DTMF signals, this function needs to be activated during the call.
To dial digits during a connected call, do the following:
1. Press 9.
Note: In Finland, press 1.
2. Dial the required digits.
The entered digits are transferred as DTMF signals.
OR
1. Press More, select DTMF and press Select.
2. Dial the required digits.
The entered digits are transferred as DTMF signals.
