By Modular hardware design SB800/ S1600/ S2400 series makes any combination of the telephone interface. The Soundwin SB800/ S1600/ S2400 Series VoIP Gateway is fully SIP and / H.323 standard compliant high density gateway that provides a total solution for integrating voice-data network and PSTN. By modular installation, this revolutionary compact voice over IP ( VoIP) gateway could be easily configured as 8/ 16/ 24 channels high density FXS/ FXO VoIP Gateway which provides voice connectivity over the IP network and to the Public Switched Telephone Network ( PSTN) .

VoIP Key Features:
• Modular design to accommodate various types of telephony interfaces.
• Both support SIP and H.323 protocols: SIP Registration and Digest Authentication; H.323 Gatekeeper Registration. SIP Single Number / Account for multiple ports.
