[OpenSIPS-Users] external applications

Fri Apr 5 01:29:55 UTC 2024

There is no generic answer to that question. It depends on your routing script and the way your system works. The code you posted before checking for INVITE could do it, but only if it is placed in the right location.

You may want to review the different types of routes used in OpenSIPS scripting [1], and what kind of message or processing is being performed in each. That may help you determine where to place your checks.

Routing of a SIP request always begins in the unnamed route block.

My question is not regarding exec command. How to capture the start of the call? I'm unable to get the start.

Per the documentation [1], input variables to the script are provided as a separate parameter to the exec command. It does not do a direct shell execution of the entire first parameter. So it should be:

exec(“script.sh”, “INVITE”);

Also, for a relative command I’m not entirely sure where OpenSIPS would look. It could be the working directory or it could be the directory from which opensips was launched. Have you tried using an absolute path? Are you setting the wdir [2] parameter?

I've used the above code inside the route block.

if($rm == "INVITE") {

xlog("Request method = $rm");

exec("script.sh \"INVITE\"");

}

With the above code , I am getting the Request method = INVITE twice in the log file. But the exec() is not getting executed.

Yes. I am canceling the call prior to dialog creation.

If your script is cancelling the call then why wouldn’t you “capture it” in the same place? Send whatever you need to whatever external entity you are using directly. You don’t need a callback to trigger if you know you are taking the action.

A created dialog being cancelled should result in a state change event – to CANCELLED I think -  so I assume you mean you are cancelling it prior to dialog creation, in which case there won’t be any dialog callback.

I am capturing the dropped call after ringing in failure_route, but  If I cancelled during the start of the call, how to capture it.

The start of the call would be when you call “create_dialog”. The dialog state for that is “UNCONFIRMED”. I’m not sure whether a dialog state change event is raised for creation. It may only be raised when the state changes after creation. But since you control the dialog creation, you can just take whatever action you desire at that time.

I tried is_method("INVITE"), but it is getting called only at the start of RINGING.

You can also use the REST client. And there are many other ways, as well.

There is no single correct answer to the vague question of connecting to any generic “external application”. You must understand your systems and decide the best approach depending on the needs and capabilities of both the external application and OpenSIPS.

Well, to execute external command from opensips you may want to use EXEC module.

this is a manual for v3.2:
