How can I execute a System command in the dialplan at every incomming call? When someone calls I want to execute a program on the server which sends the calling information to a other program.
Use the Asterisk system command for example to call the program sendfax from a dialplan:
exten => s,n,system(sendfax -d 18005551212 /stupid.txt)
This calls the program sendfax the way that you would type it at the Linux command prompt:
sendfax -d 18005551212 /stupid.txt
