Terminating a voice call via AT Command
Solution 1
I think the answer to your question is ATH0 from memory
Solution 2
While the "classic" command ATH
(there is no need to give a numerical argument to ATH) is applicable for disconnecting calls, notice that it might be configured to do nothing by AT+CVHU=1
(ignore DTR pin and ATH) for other phones (TC35 seems to not support AT+CVHU).
There is the AT+CHUP
command that always will hang up the current call, independently of ATH behaviour configuration.
The 27.007 standard also defines an AT+CHCCS (Hangup of current calls) command that can be used to disconnect calls. Also AT+CHLD
might be used to disconnect calls.
Solution 3
ATH command ends call ONLY when call was answered.
AT+CHUP command ends call whenever answered or not
Solution 4
The command you are looking for is ATH0 (Also dredged from my memory) but then confirmed with the Official Documentation

Im working on a hobby project involving an Arduino and TC35 GSM Module, all is going well really but I am wondering is there an AT Command to terminate a voice call (ATD+phone number;) as I cannot seem to find one in any of the literature I've searched through.
Thanks, Dave
