One of the ways in which we can set up a VoIP system, is by we call a proxy server. A proxy server simply, means that, if you a question - either for a Web page or in this case for a connection not you directly contact the resource. Instead the request to a middle man in the power of the request on your behalf and then sends back the results send to you. In a sense, all VPNs work as follows. You didn't request the Web page - send the request through another secure server, which encrypts the traffic and forwards it to you. The VPN system is one of the safest ways, use your Internet connection and a proxy server provides the same benefits when using it with VoIP.
If you are setting up a VoIP system with a hosted PBX plan, you get access to such a server with credentials for each user who must make calls with it. Since all that is passed to the VoIP activity of the people in your company through a single point, relieved it consolidate data, evaluate use and make corrections. Keep in mind that a user can use your VoIP number, no matter which device you currently have in their hands. This allows in contrast to a normal PSTN and mobile phone combination which are worlds, pass a one-stop spot for all telecommunications data VoIP.
This makes security easy to configure because administrators only have to secure the proxy server for it to anyone. In fact, security is one of the hallmarks of the proxy-server model. Since no traffic directly to the end user from the outer world and travel only through the secure proxy goes, there is no risk of viruses or any other transmitted malware to the end user devices. This protects you from malicious attacks, otherwise to steal confidential information or fraudulent phone calls in your account name.
Finally, the proxy-server model is understood by each VoIP application on the planet. You can simply enter the name and the credentials of your proxy server and have a working VoIP connection regardless of whether you use a computer, a phone or even a tablet. It can be from anywhere an Internet connection, international calls to child's play has.
