When the digital recording board is connected in parallel to the digital phone, the channels stays disconnected or between idle and disconnected. Why?
This usually happens when the line connection is poor, or when the board has not been correctly configured for the PBX model and the module type.
How to debug the digital recording board for monitoring? What to do if the monitored PBX or phone models are not supported by Synway driver?
The debugging procedures are as follows:
Step 1: Use ShCtiConfig.exe to do proper configurations according to the actual PBX and phone models as well as the corresponding firmware model for the PBX under the D-channel mode, referring to the latest version of the file DST Boards Supported PBX Models which may be downloaded for free from www.synway.net. Then click the button ‘Application’ to pass the configurations.
Step 2: Connect lines in parallel and keep the phone on-hook. Then use Test.exe to record silence, seeing whether there is noise within it. If any noise appears, contact Synway technical support department for help.
Step 3: Call in and out through the phone. Run Test.exe to check if any change in channel state and relative event output can be detected correctly. Once you find out some problems, use the signal tracking tool provided by Synway to seize the signaling messages and write down your performed operations step by step. Then submit them to Synway technical support department for help.
Step 4: Write the subsequent programs.
If you are monitoring some PBX or phone models that are not supported by Synway driver, please consult Synway technicians for the file DST Board Debugging Manual.pdf.
What are the supported digital PBX and phone models?
Refer to DST_PBX_Support.xls under the driver installation directory C:\Shcti for more information on supported PBXs and phones.
How to record one-way voice files while monitoring both parties of a call?
The digital recording boards can adjust both inbound and outbound volumes. Just invoke the function DTRSetMixerVolume and set both of them to -7.
