Hi,

You can run your script with an absolute path, so you can put theexternal script wherever you would like.

So you should do something like
    exec_avp("/usr/local/sbin/my_script.py $si", "$avp(should_route)");
    if ($avp(should_route) == "0") {
        send_reply("403","Not relaying");
        exit;
    }
    # continue with regular routing

The $ct in your example, or $si in mine, is passed as an argument toyour script, so you can fetch it as a regular argument, like sys.argv[1]in python.The result of the script will get returned in $avp(should_route), in myexample.

Today I have read the webyou give to me ,and I have some more questions about how to use theexec_avp() fuction , in the web I saw a simple ex：exec_avp("print-contact.sh"$ct""). The questions are where should I put my ownscript in ? And how to read the $ct in my own script (ex: python)?
Hoping for your help!

Hello,
There is no need to develop an extra module for this.
You can use the exec_avp() function from the exec module ( see #1) and
call an external script ( bash, python, etc ) that runs your logic, and
returns the result back to OpenSIPS. Based on the external script
results, in the OpenSIPS script you can drop or further relay the message.

The primary is when the server received an invite message from a sip phone, amd the server should get the src-ip and the des-ip of the session. Then send the src-ip and the dst-ip to another computer, in which we run a application that have the informations about the resource of the network (By the way,the server and the sip phones are all in an LAN). Then the application will tell the server whether it should allow this session. In another word, we want to add a judgement in the sip session.
