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.

Welcome to the Board

Your going to need help that is beyond what we provide in the open forum. You may send a private message or e-mail to any of the moderators for help. Also maybe someone will read your post and PM you.
Thanks for your understanding.

The aleen unit can be programmed through a phone and with a pc. Aleen software is required. Using this you can configure the aleen with the correct signal strings for your application. The DSU programming should be no problem for you as you've installed them before! All that being said, put in a Debut!!

How much easier is the Debut?

I have installed both so I speak from some experience! On a 1 to 10 difficulty scale, the aleen would be an 8, the debut a 2.

Debuts and DSU / DSUII's get along VERY well. Integration is a trivial thing unless you have special, special call handling requirements.
