Phone Systems....

There is something about phone systems that mandates fairly significant bumps during implementation. I've neither heard of one nor been a part of one that has gone without incident--they all seem to be far bumpier than they ought be. It's really quite quizzical; no matter how much you or the phone service plan, it seems fraught with challenges and once again, in the midst of migrating to another system, even moving to a hosted solution, we hit lots of bumps on the way. Is it me or is it.... PHONES???
