<div dir="ltr">Hi,
<div><br></div><div>I am interested to know if it is possible to do speech calls via QMI on the MC7304. I have the MC7304 with speech capable firmware, and I can do speech calls via AT commands (although the AT port might freeze after a number of calls).</div><div><br></div><div>When I tried the "--voice-get-supported-messages" I get InvalidQmiCommand, so I can't see which messages would be supported.</div><div><br></div><div>I use the master branch of qmicli.</div><div><br></div><div>I was checking the qmi-service-voice.json and saw that there are some commands defined, but maybe they are not implemented? or then the modem does not have them implemented?</div><div><br></div><div>-Sebastian</div><div><br></div><div><div>root@MR0S03B05:/opt/libqmi/src# qmicli --version</div><div><br></div><div>qmicli 1.17.0</div><div>Copyright (C) 2015
