    Voice call with Nokia 30, is it possible?

    I'm trying to establish voice call to the Nokia 30. I wasn't able so far, looks like there is no signal on the ear pins and the audio input is ignored. Looking at AT commands, AT+FCLASS should include the modality 8, which is "Voice Mode" (from the Nokia 30 AT command set). This modality is not listed when querying the Nokia 30.

    Is this phone able to do voice calls?
    Is there any setting for this?

    The voice call with Nokia 30 is possible.

    Nokia30 does not have any inbuild audio equipments like microphone or earpiece.
    Nokia30 has two alternative audio interfaces available on the
    M2M system connector:
    - digital audio
    - analogue audio
    These lines are multiplexed in M2M system connector so that there
    is only one physical audio interface.

    The default audio setting is digital. The use of digital audio requires external audio codec.

    The analogue audio can be activated with the Nokia30 configurator program.
    The analog audio interface:
    pin 23 mic +
    pin 23 mic -
    pin 26 ear +
    pin 28 ear -

    The AT command AT + FCLASS does not support
    mode 8, which is voice mode.

    The nokia30 configurator program is available from:
    www.forum.nokia.com
