By using a VPN with VoIP

One of the aspects of VoIP still was still not fully explored or realised by companies which it - security have implemented. And yet we know that VoIP is the target of hackers increasingly, listen to your conversations and hack into your systems want to. There are many steps you can take to improve your internal security, but as soon as the traffic of your premises leaves, it is challenging enough for anyone to intercept them exposed to. Although SIP-based encryption be used for calls, it can provide your ITSP. In this article, we examine the setting up a VPN for your VoIP communications and the two scenarios are routing users benefit.

Company security
Internal communication between employees may be sensitive and for this reason, it makes sense to your VoIP to the and to channel of the VPN server. This means that your conversations listen to anyone who tries with high encryption, so that it is useless meet for them. A VPN is only as safe as the remote host that you connect. So along with the security of the VPN network, you must also ensure that the server itself is not compromised.

This is only one aspect of security and tunneling to the and from the VPN server will not help if the VoIP call to an external telephone network is made which does not have the same level of security. In this case, the chain is in fact only as strong as its weakest link.

Bypass firewalls
There are cases when VoIP traffic discriminate against certain ISPs or maybe you're in a situation where your firewall can pass through not that kind of traffic. It could be a public Internet connection or a hotel room, where you also additional security would be discretion. A VPN is suitable for this type of setting that traffic has left your system as identifiable VoIP traffic at all. Tunnel "essentially" by on your VPN server with powerful encryption snooping to prevent.

A limitation is that you have correctly set up the VPN on your Smartphone, laptop or local network. So with a strange device or computer to make your calls are not the same protection offer.

These are just two examples of the use of a VPN, if using VoIP. It is part of the larger security scheme and a robust security architecture must implement in place all the elements are.
