Hardware:
We have 1-, 2-, and 4- port FXS & FXO modles, SPE Gateway connects directly to phones, fax machines, key machines, key systems, PSTN lines, or a PBX.

Esp. Security VoIP Adapter is embedded anti-blocking engine. It's popular to use in Middle East, Asia, South America ISP blocking VoIP area.


Software:
Also we have core technology for VoIP anti-blocking solutions VGCP.
Compared with VPN, VGCP has such advantages:
1. VGCP isn't blocked, because it does not use fixed port either for TCP or UDP.While VPN use standard port so it is blocked easily.
2. VoiceGuard solution is a proprietary layer 2 link protocol,it's a class security protocol whose scalability and flexibility results in not to compromise voice quality and overhead.
3. VoiceGuard for anti-blocking can work with any 3rd party: gateway/IAD/ATA/Softphone/IPphone and so on. That means you can use any existing ATA e.g.: Linksys PAP2, and add our VGBC for anti-blocking, then you can make call from PC2Phone. Our VG plug-in can work with any SIP Server like VPS.
4. VoiceGuard don't like some competitors which take effect on their own device and softswitch.
