This will handle notificatiof of call status to the rest of the system Dial Handling ============= The dial function sets up the parameters for the QMI_VOICE_DIAL_CALL service. The parameters are the number to be called and the call type, which is currently hard coded to be QMI_VOICE_CALL_TYPE_VOICE. The dial_cb callback wi then be called and will receive the call-id. --- Changes in V4 -merged qmi_voice_call_status and all_call_status_ind -several minor structure/formate changes --- --- drivers/qmimodem/voice.h | 17 ++ drivers/qmimodem/voicecall.c | 435 ++++++++++++++++++++++++++++++++++- 2 files changed, 451 insertions(+), 1 deletion(-) diff --git a/drivers/qmimodem/voice.h b/drivers/qmimodem/voice.h index 917e72f7..2344fd50 100644 --- a/drivers/qmimodem/voice.h +++ b/drivers/qmimodem/voice.h @@ -48,6 +48,9 @@ enum qmi_ussd_user_required { /* QMI service voice.
