Establish Voice Connection (not INSYS GSM 4.3 com-
pact)
The INSYS GSM 4.3 can establish a voice connection to a normal telephone. For
this, the used SIM card must support voice connections. If the SIM card supports
only data connections, no voice connections can be established. In order to be able
to use the voice functionality, you need to connect a standard phone receiver into
the audio socket of the INSYS GSM 4.3. During dialling, an acoustic signal in form
of a tone sequence can be heard in the receiver.
Configuration with HSComm
A voice connection can be established with the terminal program of the
HSComm Software and AT commands by selecting the menu item
“Terminal”.
