HMP/VOIP/TDM CARDS & PLATFORM

Flexible Authorization Strategy
This software is authorized by USB KEY with a unique serial number. Users may specify the number of authorized channels or upgrade it if not enough. As long as you tell the serial number of your USB KEY to us, we will provide you the upgrade file which you can use to upgrade by yourself.

Authorization Code Identification Circuit
The on-board authorization code identification circuit is designed for software safety. Users can apply to our company for the authorization code.

Synway’s Unified SynCTI Driver Development Platform
Synway owns the intellectual property rights for the unified high-intelligence SynCTI driver development platform. This software can be used with other Synway boards in a same environment, using the unified API functions, configuration items and event interfaces.

Supports the REFER message
Supports the REGISTER message and the authentification process
Supports the communication with SIP server
Supports the INFO message
Supports call hold
Intelligent analytical mechanism for URL Scheme
Supports the rPort setting in the VIA field (for NAT/FW traversal)
Supports DTMF transmission and reception by the method of SIP-INFO or out-of-band (RFC2833)
Internal multi-threading mechanism
Supports the heartbeat mechanism based on UDP packets

Distributed Conferencing
Independent conference resource in each port, support conference recording/monitoring;
DTMF filtering to eliminate DTMF signal in confere nce; configured as interactive conferencing without limit on the number of conferees and conferences of high-density multi-parties.

All-in-One Architecture
Universal port capability supports conference, fax, voice-processing and built-in SHT Series functions to ensure scalability, compatibility, and high performance to leverage developer time and application investment.

In-House Unified API
Protocol-independent API minimizes system development and deployment efforts and feature-rich software development kits support for Windows and Linux

FSK/DTMF Detection
Handle call connection with special algorithm for dialing handing and recognizing caller ID in FSK and DTMF modes.
