For political & economic reasons, ISP may block VoIP in your country. How to solve it using VoiceGuard™ Border Controller(VGBC)?
Due to unique architecture, when deploying 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.
Key Benefits:

Minimal Overhead and High Call Quality
Easy to Use and Cost-effective
Unlimited Call Session Number
Highly Interoperable with any Third-party Products and Services, e.g.: Linksys PAP2
Support termination server blockade
