1.6 Transaction Record
Transaction Record enables the recording of a two-party conversation by allowing two
time slots from a single channel to be recorded. This feature is useful in call center
applications where it is necessary to archive a verbal transaction or record a live
conversation. Voice activity on two channels can be summed and stored in a single file or
combination of files, devices, and memory.
The voice API function dx_mreciottdata() is used to implement the transaction rec ord
feature. It is an extension of the dx_reciottdata() function.
