Sir,
What kind help you expect?
First you studied necessary AT commands and PIC18f452(?).

I visited this given link and found the solution of my old problem and now it is solved with your information,I personally have embraced the new technologies, I think the new tools only make the web designs better. I am glad that new technologies are coming out in web design that make things easier, improved, and better looking for design.

ATDxxxxxxxxxxxxxxx;
or
ATD+xxxxxxxxxxxxxxx;

The ATD command is used to dial a number. The semi-colon at the end of this number indicates that this connection has to be setup as a voice call. When leaving this semi-colon, the connection is set up as a data call.


one more option is

AT+VTS=x

To send the actual DTMF code, you have to call this command for every digit sent. To send, for instance "*1234#", you have to send:

AT+VTD=*;+VTD=1;+VTD=2;+VTD=3;+VTD=4;+VTD=#
