[asterisk-users] Passing parameter from executable program to asterisk dialplan
I am having a problem understanding the way to retrieve some parameters to asterisk via AGI or what ever method that fits. I have an executable program that accept one parameter (CALLERID) and return customer status from the database server which can be printed in the console. #./retrive 0117473789 NAME: Franklin John STATUS: Active Can someone advice on how i can catch this values from AGI or directly on dialplan.

AGI is a protocol used to interact with Asterisk. An AGI is a separate process created by Asterisk when you execute agi() in the dialplan. From best to worst... 1) You could recode your retrieve application so it uses the AGI protocol. Then, you could set channel variables to make these values accessible to the rest of your dialplan. 2) You could cobble up an AGI to execute your retrieve application using a pipe (popen() in c), parse the output and set channel variables. 3) You could cobble up something to execute your retrieve application, redirecting the output to a file and then use the FILE function read the text file and then parse the output using dialplan functions. -- Thanks in advance, - Steve Edwards sedwa...@sedwards.com Voice: +1-760-468-3867 PST Newline Fax: +1-760-731-3000 -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

So I you suggesting that the executable to changed to output say cout SET VARIABLE name Jenny; and let the AGI retrieve them as per the pseudo you mentioned? It's a little bit more involved than than. You should google for an AGI library for your source language. It's a lot easier to use an established, debugged framework than figure it out yourself. Nobody gets it right the first time. If you follow the protocol, your retrieve application will be stable and reliable. If you just hack it up, it may work now but not under load or not in the future or not when your boss is looking or not when... -- Thanks in advance, - Steve Edwards sedwa...@sedwards.com Voice: +1-760-468-3867 PST Newline Fax: +1-760-731-3000 -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?
