Unblock VoIP--VoiceGuard
======================================================================

1. Overview
Yahoo messenger, Skype, Microsoft Messenger and Vonage offer a subscriber the
ability to "call" someone using Softphone/Gateway ATA/IPPhone/IAD. However,
several ISPs are blocking or degrading this service in order to force a
consumer to use a ISP sponsored service. States such as the UAE block this
technology outright while US corporations, such as Clearwire, claim that they
might degrade the quality of competing services by adding choppy and delayed
services.

SpeedVoIP is a leader in circumventing VoIP blocking imposed by ISP or Telco.
For vision of Net Neutrality, VoiceGuard. is created to address a growing
number of ISPs who either degrade or block voice services over their networks.
VoiceGuard. gives choice back to the subscribers or customers of ITSP. 
2. Technology
※VGCP(Voice Guard Control Protocol)
VGCP is a proprietary layer 2 link protocol working at between IP stack and
nic driver for VoIP anti-blocking. The core patent-pending VGCP is industrys
most state-of-the-art voice service provider class security protocol whose
scalability and flexibility results in not to compromise voice quality and
overhead. VGCP controls and monitors full voice signaling and media flow
intelligently, meanwhile disguises sip and rtp packets into normal allowed
data packets such as DNS and TFTP, and makes two-way encryption and decryption
driven by user-customized policy. VGCP is fully transparent to upper SIP proxy
or UA which means VoiceGuard. can work with any 3rd-party
Softphone/ATA/Gateway/IPPhone/IADs and SIP proxy or server not like some
competitors which take effect on their own device and softswitch.
※SidePass 
Due to unique architecture, when deploying VoiceGuard. Border Controller(VGBC)
at customer CPE side, VGBC can work in the way similar to that of soho router,
but it only encrypts and decrypts SIP and RTP packets on link layer, not to
handup these packets to IP stack for forwarding while bypassing other data
packets originating from SIP terminals. In this scenario, peak throughput and
minimal CPU overhead can be easily achieved.
※TrafficDisturb 
Current leading carrier-class VoIP blocking platform such as NarusInsight can
detect VoIP traffic with a special algorithmtraffic classification in the dark
which filters VoIP traffic based on behavioral-signature model. Compared with
previous one of payload-signature model, NarusInsight is more sophisticated
and robust. After deep study into traffic behavior of SIP UA, Proxy and
Registrar, VoiceGuard. can real-time incorporate light-weight traffic for
puzzling and bypassing VoIP blocking system without consuming more bandwidth
and compromising voice quality. Even in some circumstance, VoiceGuard. can
simulate traffic behavior of universal data networking protocol such as OICQ,
MSN and so on.
