VoIP is the rising buzzword for various Service Providers and organizations. Voice over Internet Protocol (VoIP) saves lot of hundreds, even thousands, of dollars in a month. But its poor voice quality feature becomes a major hindrance to switch to VoIP.
Service providers and organization face difficulties in understanding VoIP technical know-how as all the major VoIP players are not capable of providing the desired technology for perfect calls.
At Ascent Telecom, Service Providers will explore that they thoroughly understand the technology and provide all the technical requirements through our Symbian based Mobile Softphone and PC windows mobile dialer. These phones are available with G.729 Optimized Codec for any personal or official calls.
They acknowledge the needs and expectation of every caller and Service Provider. Their approach to maintain voice communication interaction in the presence of poor network performance is highly appreciable among their clients.
Moreover, Service Providers can explore thoroughly the technology and all the technical requirements through their "Voice quality Enhanced" Symbian based Mobile Dialer and PC Windows Based Softphone.

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.
