1) For standard wav files: Single-channel A-Law, μ-Law and 8-/16-bit linear PCM, IMA-ADPCM, Dialogic-ADPCM (VOX), MP3, GSM and G.729A are supported. For stereophonic recording which is invoked by SsmRecStereoToFile, A-Law and μ-Law are supported.
The offered cards have an embedded ARM processor, DSP architecture, and built-in PCI plug-in design. In this card, the high resistance input port and record gateway can directly bridge the trunk line which needs to be monitored. Additionally, offered cards can be made available in bulk quantities. Argentina: Costa Rica: El Salvador: Guatemala: Honduras. You've just added this product to the cart: Cognex VPM-8110X-5010 RevA Image card for COGNEX MFG:801-8422-01.
2) For plain files (i.e. files without header information): Single-channel A-law, μ-law, 8-/16-bit linear PCM, IMA-ADPCM, Dialogic-ADPCM(VOX), MP3, GSM and G.729A are supported.
3) For standard MP3 files: Single-channel MP3 is supported.
Which compression format does recording use, and at what rate?
The following recording compression formats are supported:
1) IMA-ADPCM or Dialogic-ADPCM (VOX): Compression rate of 2:1, i.e. voice data are generated at 4kbps.
2) GSM: Compression rate of 5:1, i.e. voice data are generated at 1.6kbps.
3) MP3: Compression rate of 8:1, i.e. voice data are generated at 1kbps.
4) G.729A: Compression rate of 8:1, i.e. voice data are generated at 1kbps.
How to play WAV files recorded by a sound card with a Synway voice board?
The files can be directly played by Synway voice boards if the file format is supported by our product. Otherwise, they have to be converted into a supported wav format with third-party software tools such as Cooledit.
Why are noises sometimes heard in the process of file playback?
This generally happens when voice data are corrupted or when incorrect play-format is used to decode an unformatted voice file. Another reason is the voice codec being used to play files is unsupported by Synway boards.
How to play or record GSM, MP3 voice files?
To play or record GSM, MP3 voice files, you should first modify the configuration item under Section [SystemConfig] in the file ShConfig.ini to GsmCodecEnable=1, and be sure to install necessary codec engines (The engine for GSM is usually carried by Windows operating system while that for MP3 could be acquired from the DEMO package released at our website).

The DST range of single-slot solutions for logging and monitoring behind PBXs, fits into a variety of PBXs extension tapping environments, including connection between the PBX and the proprietary handsets providing passive monitoring of the voice conversation and D-channel (call control). A variety of telephony events such as call taken and key pressed are automatically decoded and sent to recording applications for a powerful set of functions and high integration with PBXs. As a modular structure, the DST series can be customized to provide 24, 16, 12, 8, 4 ports (per slot) ideal small offices up to large call centers. For that reason many developers worldwide depend on DTP series to create robust and high capacity systems in central office and Telco environments.
Multiple PBX Support
A single board interfaces with a majority of PBXs on single hardware platform. With much field expertise, Synway can configure for your PBXs. Structured with motherboard and functional module architectures, a single DST board can be configured freely from 4 to 24 ports based upon special application needs.
Flexible Configuration
Structured with motherboard and functional module architectures, a single DST board can be configured freely from 4 to 24 ports based upon special application needs.
Firmware Upgraded
No need for hardware change and special upgrading tools, a simple firmware upgrade allows DST to fit into different PBX environments.
On-Board Audio Jack
Monitors up to 24 ports in real-time or playback audio files with on-board audio jack resources.
Wide Spectrum of Trigger Events
DST initiates and terminates recordings based on voice activity, raw D-channel, DTMF, programmable tone analysers, and Call Progress Monitoring (CPM) events.
Voice Processing Capability
A large selection of voice CODECS for developers, including G.729A, G.711 A-law, μ-law, Linear PCM,IMA-ADPCM, MP3, and support VOX format.
Support Direct Windows WAV Format
Data is saved in WINDOWS WAV format directly, and can be played out by sound card with no format conversion.
Security for User Software
The built-in authorized code identification circuit is included to provide an exclusive authorization code for protecting users' software security.
Extensive PBX Support
Compatible with international deployments, the DST taps 2-wire, 4-wire, BRI and full duplex PBX's. The list of PBXs the DST supports is constantly growing. Please feel free to contact Synway for custom configuration.
