Abstract
A transmission playback device for selectively storing discrete transmission data is configured for use with a telecommunications accessory device. The playback device includes a memory assembly having a pair of identical storage buffers. A first storage buffer has memory designated for continuously recording transmission data, and a second storage buffer has memory designated for selectively storing a discrete message from the transmission data. A controller exchanges the designations of each storage buffer upon a request by a user such that the second storage buffer becomes designated for continuously recording transmission data and the first storage buffer becomes designated for selectively storing a discrete message from the transmission data.
