importance of security in VoIP <

VoIP for a long time, was called as a cheap method and non-secure communications to the voice packets are passed through the establishment of public Internet. It is a control over the flow of packets and therefore very uncertain.

unsecured communication does not belong in the business environment for serious and therefore VoIP is never treated as true means to secure the conversation about sensitive topics.

speech restrictions, this is another major reason hindering the growth of VoIP in the enterprise and individuals seriously.

Possible solutions

are two of the leading security solutions to this problem:

The first is implemented in VPN tunneling client devices most softphones and client-side PC Softphones Mobile.

Second, and rarely shown solution is encryption / decryption “of the VoIP packets.

VPN tunneling Explained

The client makes a connection with our own secure server, and then start sending data over the secure channel dedicated.

The protocol between the client and the server is a declared and known as the log with OpenVPN, PPTP, Microsoft etc.

encryption explained /

The client encrypts the data before sending it over the Internet.

Encryption is a sense of belonging and done algorithm, as a developer of encryption / decryption.

The data is known, is then sent to the server, which uses the same algorithm to decrypt the data sent by the SIP server.

Services & ; disadvantages of encryption / decryption more Tunneling

Since then, the tunnel uses the standard protocol from which it can be easily detected by a firewall fire. blocked

Due to the easy detection of the tunnel may be interrupted or at any level.

As a VPN tunneling is accessed by independent programs, most of the time, to not recognize the PC firewall and not allow. Some VPN tunnels enable soft phones use more than one protocols such as PPTP and one of the ports are used. These ports are usually blocked by DSL routers. Therefore, for tunnel-based soft phones to create quite a problem a couple of steps works behind a firewall.

encryption / decryption solves all these problems and makes the conversation smoothly and operate in all of these conditions is also problematic. “/ P> There is the server component of the encryption / decryption also developed and managed by the seller, therefore, more efficient load distribution can be done in case the encryption / decryption. In addition, because the server SIP protocol encryption is sensitive, load balancing can be based SIP dialogue. This means that the server is the message to any server.

been sent to the same recall for the distribution of load or load-balancing and that the processing fee is much more effective if encryption / decryption .

The voice is much safer in case of encryption. / decryption, because the algorithm is proprietary, and pirates are completely unknown. “Since standard protocols are in the tunnel, where the cracks for the same are known.
