2.6 Placing a Voice call<br />
<strong>GE863</strong>-<strong>QUAD</strong> / <strong>PY</strong> <strong>Software</strong> <strong>User</strong> <strong>Guide</strong><br />

Before a voice call can be placed, it is recommended to check if the mobile is registered on a network<br />
(see par. 2.5.3.1) and if the signal strength is enough to ensure a call can be made (see par. 0).<br />
2.6.1 Voice call device set up<br />
2.6.1.1 Set the device in voice mode<br />
• Send command AT+FCLASS=8<br />
• wait for OK response<br />
NOTE: This command may be omitted if the modifier ";" is added at the end of the ATD command<br />
after the number to be dialed.<br />
2.6.1.2 Set the desired audio path active<br />
The <strong>GE863</strong>-<strong>QUAD</strong> / <strong>PY</strong> has two different audio paths:<br />
- internal microphone/ear (MT)<br />
- external microphone/ear (HF)<br />
Usually the internal path is used for a handset function, while the external is used for handsfree<br />
function. There are two way to switch between these two paths:<br />
- SOFTWARE: by using the command AT#CAP= (with n=1 OR n=2)<br />
- HARDWARE: by setting AT#CAP=0 and setting the AXE input high (internal MT) or low (external<br />
HF).<br />
If only one path is needed, then it is preferable to use the internal one (MT).<br />
TIP: when Hardware control is not needed AXE pin can be left unconnected.<br />
TIP: the audio paths can be switched also during a call in both ways.<br />
• Send command AT#CAP=<br />
where:<br />
= 0 for HARDWARE control with AXE input<br />
= 1 for external HF path (regardless of the AXE input status)<br />
= 2 for internal MT path (regardless of the AXE input status)<br />
• wait for OK response<br />
