Triggering a Handphone call using Arduino

Hi i am trying to make a handphone call via arduino mega 1280. With the command below i am able to make the phone show "Callling 96631890" then "connecting 96631890" but it will not reach 96631890 nor ring . I checked the call list but 96631890 don't appear . Anyone know what could i add to make the call sucessful ?

void setup() { Serial1.begin(9600); delay(25000);

} void loop() {

Serial1.println("ATD96631890"); delay(5000);

do { delay(1); } while (1>0);

}

Wow, the AT command set, really testing my memory, so i might be wrong. Do you have touch tone service? I think ATD dials with pulse dial, while "ATDT" dfoes a touch tone dial...

I tried ATDT and ATD, both can't dial the cellphone number but i am able to dial my Landline House phone number sucessfully with both ATDT and ATD!!!

werid anyone know how to dial the Cellphone number successfully ?

I'd recheck the cell phone number and make sure you are using all the required numbers.

Well i believe i am using the correct number for dialling, Because i saved the number I.E apple as 96631890 , as i execute the ATD command, the phone show "Calling Apple" "Connecting Apple" but cut off immediately after that. If i change the number to my house phone number (Landline), it works !! but i need to work with another cellphone!!!

Anyone know what's the problem ?

Anyone know the reason why i cannot dial to cellphone ? Cannot find the information anywhere :cold_sweat:

What hardware is doing the dialing?

Sony Ericsson T68I moblie Phone

Presumably you can dial the number manually ok?

Yes i am able to dial manually. Anyway i also found one thing werid is that although i can dial my house number sucessfully but when i pick it up, i can't hear anything nor the other user can hear me talking.

It is a few years since I did this, but I recall that the mobile I was using used an extension of the basic AT command set in order to set up and tear down calls. Have you tried connecting your handset to a PC and just controlling it manually using hyperterminal or similar? Probably easier than trying to figure out how it works using a sketch.

try this atdXXXXXXX;
or atd[][;]

XXXX is phone number
