I try to forward an incomming call via this AT-Command: 

AT+CCFC=1,1,"+4930xxxxxxxx",145;

But it isn't working (on the M10 Quectel GSM Shield from Arduino).

My second approach is doing this with an USSD-Line wrapped in a AT-Command like this:

AT+CUSD=1,"**21*+4930xxxxxxxx#",15

but I also receive an error. Anyone know what's wrong?

UPDATE: I found out that there its necessary to choose mode "3" at the 2nd position. That means that the following telephonenumber is going to be registred. Like so:

AT+CCFC=1,3,"+4930xxxxxxxx",145,1,1

Unfortunately I can't save the current incomming number, before doing the forwarding process. After setting up the callforward-AT-Command the call goes directly to the forwarded number. So it seems that I have no access to the new telephone number. Any workaround for this?

  • Your posted code is showing stylized quotes “ “ but I suspect you want regular ones " ". Are you using regular quotes in your original code? – Eric J. Nov 03 '15 at 23:10
  • Oh you are right, but there is no change after replacing the quotes. I guess the serial monitor just see it as regular " quote — edit: changed the quotes above to avoid any misreading – erikfx Nov 03 '15 at 23:27
  • Are you sure your specific device supports call forwarding? – Eric J. Nov 03 '15 at 23:31
  • regarding to this manual it should support this: http://www.quectel.com/UploadFile/Product/Quectel_M10_AT_Commands_Manual_V4.0.pdf — on page 44 there is the AT-Command for forwarding. By commanding: "AT+CCFC=?" there is also feedback. – erikfx Nov 04 '15 at 08:29
