Description:
Features:
1) Module designed structure: separated mainframe and voice card, various
assembled way, easy extend
2) Standard communication protocol: SVG6116 supports mainstream protocol-voice
over IP (VoIP) using SIP (session initiation protocol) 2.0
3) High-quality voice: using the special DSP with voice quality enhancements,
such as dynamic voice jitter buffer (DVJB), voice activity detection (VAD), comfort
noise generation (CNG), echo cancellation (EC), packet retrieve; it provides
the same voice quality as PSTN phone
4) Support all kinds of voice encode standard: supports G.711A, G.711U, G.723.1,
G.726, G.729A/AB protocols for different broadband
5) Bandwidth control and QoS: control the bandwidth of voice stream and data
message though four Ethernet ports switch inside; and by using the QoS protocol
in layer 2, 3 to set up the priority of communication, guarantee the quality
of voice communication first
6) Applying for various applications
7) Supports FXSIP, FXSFXO, FXOIP all directions calling, as well as port
Trunking, link aggregation control protocol (LACP)
8) Auto-answer function: when calling from PSTN reach gateway, it can answer
with voice to guide the user to make a second dialing or change to the hotline
