Yeah, I like the ability to change the CO ports to AUX so that if one is used for paging access, it can't be put on hold. Very handy feature that many systems even today lack. Just remember that voice calling on intercom is one-way for the 3503, 3508 and 6414 models. You'll need speakerphones, mmodel 3593, 3598 or 6414S to have hands-free answer back.
