Hi all,

After stalking this forum for several years I have finally got around to registering. Although trained as accountant I have spent the last 20 years handling IT and phone systems at almost every company I have worked for. I have participated or headed the installation or upgrade of Rolm, AT&T Definity, Nortel, NEC, and InterTel systems.

As my topic says over the last 20 years it seems that the line between key systems and PBX has blurred to the point where there is really no distinction anymore in terms of features.

Am I missing something? If there is a difference can anyone furnish a concise list of what puts a system in one category or the other?

Thanks and glad to be around such great experience and resources.
