Benefits of a VoIP telephony system for your business

An alternative telephone service which was always popularity in recent years is Voice over Internet Protocol services more commonly known as VOIP. A number of popular brands of VoIP services are already market, offering telephony services to individuals and businesses, both for the flat monthly fee, regardless of local, long distance, or even international use. Most of the major VoIP providers also lets you use conventional phones,and able to call any phone you may be able to achieve through aphone was connected to a public fixed telephone system.

VOIP Definition:

There are actually three different types of VoIP services, which are commonly used, although the type that is most commonly used for commercial purposes is VOIP which is implemented by using an analog telephone adapter (also known as ATA.) The use of an ATA you can use a standard Telephone for their VoIP Service and you simply plug the phone into the card instead of a wall telephone jack. The ATA converts the analog signal into a series of digitalpackets that are sent through an Internet connection to broadband, where they are distributed in exchange for your order to complete their call.

Advantages of the rules of VoIP telephony service:

The benefits of Voice over Internet Protocol there are many, and For this reason, a number of companies opting for VoIP through standards public phone access. Most VoIP providers include phone prize shared
services such as caller ID, call waiting, Call Forwarding, Three-Way Calling,and voice mail with a monthly subscription free, and just a flat load applicable to all calls made within the month, instead of separate local and long distance charges. In most cases, voice mail can be controlled through the Internet as easily as e-mail messages can also be saved and sent as an email.

Why the ATA that most VoIP providers use simply plugs into a broadband Internet access, business Travelers can also take an ATA and phone to hotels or other places and still have access to their corporate phone and VOIP service simply by connecting to an available connection. Software known as softphone can also be installed on any laptop with a microphone,speakers or headphones, and a wireless LAN for VoIP calls can be place without the need to travel with an ATA and physical phone.

The most secure encryption and decryption for VoIP Services

Reliability and security has always been a main concern for all organizations and Service Providers, especially when it comes to business communication. No company wants to make any mistake for building and maintaining relationship with their clients, colleagues, or senior managers.

Telecom companies deliver carefully planned and multi-layered approach to secure your VoIP communication. Our unique and secure encryption and decryption technology enhance the voice quality and brings tremendous results.
Presently, some companies are offering PC SIP Softphone embedded with GIPS Advanced Voice Engine, Symbian Based Mobile dialer, Windows Mobile based Mobile Softphone.
To enjoy more about this technology one has to understand what best we can do to secure the communication networks.
Basically, the Voice/ Voice signal is converted into digitized and broken portions (packets) and sent through a series of routers until they reach the recipient. These different packets may take different routes for reassembling at one destination and turn back the voice, while, making your communication more secure.
This voice encryption is based on 16 bit algorithm with RSA start session key to secure communication. It will save calls from violation by the third party or the hackers. Moreover, it will prevent the communication.
This developed technology has the special features of sending the voice packets through the block ports also. These coding or packets are not identified by the port blockers or the hackers. Simply, they let it pass the way by identify a normal VoIP traffic.
So, it acts as an advantage to most of the organizations and Service Providers. Apart from this, encryption and decryption techniques solve various purposes, like Service Providers can:
· Enjoy a genuine encrypted voice communication without any loose of data or voice packets
· Confidentiality Secure their VoIP conversations
· Manage the obstacles created by hackers/ block ports

In simple words, the multiple layers of security mechanisms easily recognize and parse VoIP protocols and perform deep inspection of the VoIP packets and analyze the VoIP payload to secure the communication.

In VoIP - How is Encryption better than VPN Tunneling

Importance of Security in VoIP:
VoIP, for long, has been termed as a cheap and unsecure mode of communication whereby the voice packets are traversed through public internet. There is control over the packets flow and hence highly unsecure. Unsecure communication never gets its due place in serious business environment and hence VoIP is never treated as a genuine secure way of conversation about sensitive matters. Along with voice quality restrictions, this is another main reason for hindrance in VoIP growth among serious enterprises and individuals.
Possible Solutions:
There are 2 prominent solutions to this security problem:
First is VPN Tunneling being implemented in client side devices plus client side PC softphones & Mobile Softphones.
Second, and the rarely present, solution is “Encryption/Decryption” of VoIP packets.

VPN Tunneling Explained:The client creates a dedicated secure connection with the server and then start sending data through this secure dedicated channel.The protocol followed between client & server is a declared and known protocol like with OpenVPN, Microsoft PPTP etc.

Encryption/Decryption Explained:The client encrypts the data (both signaling & RTP) before sending them over internet.The encryption of data is done through a proprietary logic & algorithm that is only known to the developer of the encryption/decryption.The data then is sent to the server where the same algorithm is used to decrypt the data and sent it across to the SIP server.

Benefits & Disadvantages of Encryption/Decryption over Tunneling:Since, tunneling uses standard protocol hence it can be easily detected by any firewall.Because of easy detection the tunnel can be blocked or stopped at any level.As VPN tunneling is invoked by independent programs (like softphones), most of the times, many PC firewalls do not detect and authorize this. Some VPNs tunneling enabled softphones use more than one protocols such as pptp and more than one ports are used. These ports are most of the times blocked by ADSL routers. Hence, tunneling based softphones create quite a few problem behind firewall functioning.Encryption/Decryption solves all these issues and make the conversation work seamlessly and make it work in all these problematic conditions as well.

Since, the server side component of Encryption/Decryption is also developed and handled by the vendor, hence, the load balancing can be done effectively in case of Encryption/Decryption. Moreover, since the Encryption server is SIP Protocol sensitive, load balancing can be done on SIP Dialog basis. That means server can remember which message was sent to which server.
Same holds true for load distribution or load balancing as well, whereby, the load handling is done much more efficiently in case of Encryption/Decryption.

Voice communication is far more secure in case of encryption./decryption because the algorithm is proprietary and hackers are completely unaware of it. Since, standard protocols are followed in tunneling hence the cracks for the same are also well known.As encryption server gives control over each data packet also, compression algorithms can be easily used such as RFC 2508.
