The most important part of configuration is located inside MiaRec.ini file (see C:\Program Files\MiaRec Business\Bin\MiaRec.ini).
MiaRec.ini has a standard INI file format (see Wikipedia: INI file format).
The basic format is following:
# This line is a comment
; This is also a comment
[Section String]
Key Name = Value String
Where:
Some of most important configuration parameters are described in documentation. Others (rarely used) are described inside INI file itself in comments.
MiaRec reads the configuration file during a start or upon a request from Telnet console. This means that "MiaRec" service should be restarted after INI file is modified. Alternatively, instead of restarting the service, it is possible to send command "reload config" from Telnet console. The latter method is recommended when there are active calls, which are recorded at the moment.
