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.

Distributed Architecture
Thanks to the distributed architecture, the HMP Client and the HMP Server can be distributed on different hosts. The HMP Client can be connected with the HMP Server in two modes: Active and Passive. Multiple HMP Clients can be connected to an HMP server; and the channel quantity on each HMP Client can be customized. Such design effectively unties the restriction on channel amount, making capacity expansion easy.
