Hey Telecomtex.
Welcome to the site! That is pretty neat that you installed that system, We need more Altigen people on the forum Ramjet has been lonely!
Tell us about that install. What kind of issues did you run into. What is their network running on?
Also does anyone have some screenshot of the User Interface to do Moves, Adds and Changes? I would be curious to see what Altigen's interface looks like.
