It's this program.
They keep reappearing because those files are needed to run the program. When you delete them and run the program again (may be running in the background and starting up when computer starts up), the files are recreated.
First of all, in a production environment you shouldn't be getting rid of anything that you haven't already replaced.
That said, you can lease a SIP trunk and connect to it with a softphone and/or VoIP desk phone. This is a very affordable SIP trunk option https://sip-trunk.digiumcloud.com/plan/minute
Here's a free softphone http://www.linphone.org/
Hello! Thanks for your reply.
My name is Rafael and I have background in Computer Sciente.
The app is based on Linphone but with a enhanced encryption (AES-256 instaad of AES-128).
We offer our own VoIP client that comes with a lot of security enhancements and it's ready to use (https://itunes.apple.com/us/app/guardlock-secure-encrypted/id1028498728?mt=8). If you do not feel safe using it, you don't need to trust us and can use the original Linphone app (source code here: http://www.linphone.org/) to connect to our server. Once it's end-to-end encrypted with the keys generated on the users's own devices at each call, you can be sure by yourself that the call is really secure. :)
Other important informations about the security are the use of ZRTP protocol to avoid man-in-the-middle attacks, new encryption keys generatet on the user's own devices at each call and end-to-end encryption.
Please feel free to clarify any doubt.
I didn't actually realise they offered an unlimited package! Most of the calls I make are to the UK and I pay roughly 1p per min (including VAT).
I use linphone on both my computer and Android phone and have no problems. I'm sure it'll work fine with Ekiga.
Edit: I've just looked on Skype's site and their euro unlimited package is $10.34 per month, Freespeech's is about $15 per month, with a £15 setup fee (they credit your account with £15, though). Freespeech give you an 0844 number and a local number and missed call handling, too.
There are plenty of companies offering SIP deals, though. There may be better offers to be had with a bit of digging.
Is there a reason the SIP client has to be web based?
If you need a software based client, I like Linphone. Another good option is Zoiper. There are desktop and mobile clients for both of them. You just have to put in the SIP credentials for the extension, and they can use a headset on the computer to make calls.
Just a note that you could use softphones instead of hard phones to save money but it really helps to understand things with the hard phones. These are pretty nice for $45/each. If you need to go the softphone route, Linphone is a good multi-platform phone. SIP is the only protocol that you need to worry about (it is widely supported and simply provides telephony over IP networks). You could install Linphone on your smartphone and also on your PC/Mac and run FreePBX as a virtual machine under VirtualBox or the like in order to make this truly expense-free (assumptions here obviously).
The first time that you dial a real telephone number with a phone on your own PBX, the call will probably not go through. But it will eventually. Then you'll be hooked - this is both fun and profitable.
The SIP trunk will come with at least one "DID", which stands for "Direct Inward Dial". This is just a fancy way of saying that you get a phone number for incoming calls. You can let the PBX answer the calls for a "press 1 for phone 1, press 2 for phone 2, etc" type of system or you can assign a DID to each phone (this is where it starts to cost money but the costs should be trivial in the context of what you're learning).
Have you recently installed any application that has video/voice/chat capability? Likely something open source, but not necessarily.
This is likely coming from an app that is utilizing the liblinphone open source library.

Try Linphone if you're looking to something with the SIP protocol.
Just a note: it supports ZRTP encryption, but it's not enabled by default, you need to enable in the setting. And it doesn't support encrypted messages, only calls.
Signal (iOS) and Redphone (Android) from Open Whisper Systems are interesting options too.
For client software: Linphone It has encryption and even offers a free SIP service, but you can use it with whichever VOIP provider you like. I've not looked into pricing for providers that allow calls to old-style phonelines. I've used it many times to video chat from my desktop to people using the android client on their mobile internet-connected smartphones and it works great.
