I had this thought on and off. You can send the call with a specific caller ID and intercept that - to not make the phone ring. (However, this assumes the CID will be sent correctly & consistently.) But of course, if you want to make a real test call, then you need to pay for a real call. -Avi On Wed, Feb 4, 2015 at 5:16 PM, Michael Jerris <mike@jerris.com> wrote:

About the only way to do this is to actually make a call occasionally to see if its up. Any approach to automate this with scripts and ESL to originate a call and collect results can do this, with the side effect of your phone ringing all the time, and the usage involved.

Hello,

I need advice - what kind of monitoring or testing applications (OS,free) do you know for testing the uptime of a VOIP landline number provider and phones (voip + landline) behind a freeSWITCH ?

Since this post is a start for a educational journey I am also glad for literature documentation regarding monitoring of telephone system, preferable with open source applications.

All the best Arfst

@Michael ok, how does such a setup specifically looks like or which components are used? @AVI The CID will be sent consistently.

I still have the open question: How to monitor/log and automate test calls? Which software or setup could be used for that? Which software, setup can detect if a targeted phone (Landline/Voip) is ringing and hangs off automatically?

This is a bit of a do it yourself (DIY) project. Most likely there won't be anything existing that does exactly what you want in exactly the way you want it. I suspect the lowest barrier to entry for you is to experiment with fs_cli or ESL in generating test calls with the originate API. Look at the execute_on_* and api_on_* variables as well. You may want certain things to happen, i.e. as soon as you receive a 183 you hang up, so maybe execute_on_media=hangup or something like that. This is not unlike learning how to build stuff with Legos. You've got a lot of pieces and you'll need to start putting them together and see what it looks like. Start by looking at the examples on the wiki and go from there. It's a lot of effort but when you figure it out and your tool actually works it's a great feeling. -Michael

I also would be glad to get some keywords for this topic, because my own research only let me find commercial providers.
