Overview<br />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.<br /> <br />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. <br />2. Technology<br />※VGCP(Voice Guard Control
Protocol)<br />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.<br
/>※SidePass <br />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.<br />※TrafficDisturb <br />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. <br />3. Key Features<br
