Hello Asterisk Users, I wanted to know a simple way in which I could read some file from a console (say by using system command) and based on that either return true or false back to dialplan. Is there any built in command in Asterisk for that ? What are the options do I have ? Are there any sample code to do so ? Thanks a lot Regards -- Arpit Mehta Graduate Student Department of Computer
