EHS6-A Silent Voice Prompts and Calls | Thales IoT Developer Community

February 19, 2018 - 2:57pm, 1873 views

I have Java application running which keeps up ssl connection to the cloud and monitors periodically network connection health with AT commands.

Playing voice prompt fails to give any sound very often. All responses from AT command are allways the same for audible and silent case:
AT^SAFH=0,"a:/beep.amr"
^SAFH: 0
OK
+CIEV: voiceprompt,1
+CIEV: voiceprompt,0

Also calls sometimes are fully silent and with current sequence (voice prompt, wait 10s, call) and timings outgoing calls are all silent. Incoming calls sometimes work sometimes not.

Is there available any diagnostics commands for getting further information of related audio states? Any ideas to try out?
