Hello. I have a DSU-II 1632 with a Aleen 4000 voicemail system and can't figure out how to get them to talk to each other. I've programmed and installed about 5 or 6 DSU-II's but never had to add anything using the ATI-D. Can you tell me what wiring configuration to use? The voicemail has an RS-232 port on it and I have an RJ-11 to serial adapter.
