Systems and methods for capturing various types of communication signals are provided. An exemplary method comprises the steps of: installing a first type of tapping devices to obtain a first type of communication signals; installing a recording system that is coupled to the first type of tapping devices; receiving of communication signals of the first type from the first type of tapping devices via the recording system; recording the first type of communication signals via the recording system; installing a second type of tapping devices, after the installation of the first type of tapping devices, to obtain a second type of communication signals; receiving of communication signals of the second type from the second type of tapping devices via the recording system; and recording the second type of communication signals via the recording system. The recordings of the first and second types of communication signal coexist on the recording system and are selectively retrievable during playback.
