I am working on a Magix system that is currently all analog trunks. They're going with a PRI from XO so my question is, once the DS100 is installed and configured what is the next step? I know enough to expect to lose all line appearance buttons. I know to create line pool access buttons and call park buttons. But what is the immediate next step after installing the PRI so it can handle calls? Does the Magix work like the Nortel and have a default line group? What do I change in VM to answer the incoming calls? Currently you add lines as members to the cover group but how does that work when you have no lines? I am reading the manual but I always like to ask questions.
