The SHN VoIP series supports H.323 and SIP. A single board offers call connectivity and voice-processing capabilities on 32 ports. It is widely used for enterprise-class IP telephony network applications and provides call centers with voice over IP solutions.Typical product applications include interactive teleconferencing systems, IP-Gateway, IP call centers, VoIP-based telecom value-added services, etc.

 

Support PCI2.1 bus and hot swap.

 

A single board offers 32 channels with full-duplex IP call compression and decompression in G.729A, G.711(A-law/µ-law), ADPCM formats, etc.; support RTP.

 

Supports H.323 and SIP, allowing full compatibility with equipment of other make.

 

Like Synway's PSTN voice boards, each channel on the board is equipped with voice-processing and teleconferencing resources.

 

Independent tone generator produces single tone and dual tone (DTMF) at any specified frequency; Independent tone detector detects single tone and dual tone (DTMF) at any specified frequency.

 

The best DTMF detection algorithm in the industry facilitates accurate separation of DTMF signals mixed in strong voice signals.

 

Support adaptive echo cancellation.

 

Distributed IP-teleconferencing capability, allowing random multiple interactive teleconference without the need for an additional teleconference board.

 

Support H.100 bus; demonstrates superb data transmission capability between boards.

 

Unified Synway SHCTI driver development platform; can be used in line with other Synway's voice boards, thereby creating a composite application system for VoIP and PSTN connections.

 

Each board has an exclusive hardware serial number written in the firmware to distinguish itself from other boards and prevent piracy; The on-board authorized code identification circuit is designed for users' software security; Users can apply to Synway for the authorized code.
