Is it possible to dial a number, get connected, count ringing and then submit DTMF : **12127773456
(not VoIP, using local SIM just like you would do manually)
record until silent (max 4000 ms) to files 'f-[0-3]-[0-2].out'
hangup
wait 2000 ms
You mean Step 1, 2, 3 i can do with B4A? ( i cant use cloud solution because its for Emergency fallback
call via my APP to a Emergency fire alarming PSTN/ISDN number, where via GSM protocol i wanted to
send DTMF when internet was down)
