Hi,
You can connect the external source to the new TMU as you were using before, or use a WAV file.
If your PBX has a LSU-E can use the TMU or the VSU for the WAV file
If you have a MGU is simple to use WAV files.
WAV is the file format to be used for RVA messages, with one file per
message. The recording format is Pulse Code Modulation (PCM),
according to ITU-T recommendation G.711 (A- or m-law, mono,
sampling frequency 8000 Hz). Files must be stored in little-endian format
(which is normal when recording on an Intel-based PC). Standard tools,
such as Microsoft Sound Recorder, can be used.
