i am a little confused about statements in the forum, documents and distributor about voice call with the mc7304. the distributor said:
“… In general the MC73xx product family does not support voice calls only data calls…”
the document AirPrime MC73XX-8805 AT Command Reference_V4 mentioned in chapter 11: Audio Commands:
This chapter describes commands used to configure and manage
audio-capable devices, including:
and some audio commands are only available with firmware 06.xx.xx.xx or higher
in the forum entry
there is a statement about the mc7304 and voice with the a firmware SWI9X15C_06.02.16.00 r21356 CNSHZ-AR-BUILD 2014/04/08 08:48:50
the document AirPrime_MC73xx_USB_Driver_Developers_Guide_Rev1_1 describes a audio usb interface, but i dont see an audio interface
i was able to make a voicecall (at least the signalling) with the vodafone approved firmware SWI9X15C_05.05.39.02 but not with the generic one SWI9X15C_05.05.58.00.
my questions are:
is the the mc7304 supporting voice cs calls?
when it is supporting, do i need a special firmware?
why is there a firmware SWI9X15C_06.02.16.00 from 2014 when the most recent one is SWI9X15C_05.05.58.00 from 2015 at source.sierrawireless.com?
when voice is supported, is there a audio usb interface available?
thanks and regards
