Call logging in trunked communications sys- tems is generally accomplished with modified dis- patch consoles or through the use of fixed-frequen- cy receivers (control stations). When using the modified dispatch equipment approach, the audio is detrunked prior to recording. Audio for each talk- group is on separate recorder tracks. When using the control stations approach, the over-the-air audio is captured while another device simultaneously captures the system call data. The call data is recorded simultaneously with the audio, allowing later retrieval of the call audio based on that call data.
