Being a technology guy, I generally like to use and learn the newest (hopefully more effective) ways to get things done. In the phone business that means the PBX model rather than the Key System/KSU model. Basically if you’re used to telling someone to pickup line 2, you use a KSU. If you transfer calls or use park orbits you use a PBX.
What I’ve found is while many businesses want the new underlying features (VoIP lines, telecommuter support, cell phone integration, email integration) they often don’t want to learn the PBX model when they’ve spent years or decades with KSUs. The PBX model scales better and is the modern approach, so most modern phone systems follow it. But there’s nothing wrong with the KSU model for small businesses.
I’ve realized one of the great strengths of the Talkswitch and Allworx phone systems over many competitors is both support KSU and PBX modes. For example a recent business had old GE 4 line KSU style phones - the owner had used KSU phones for decades and wanted the new phones to work similarly. At the same time they wanted more - an autoattendant, voicemail to email, follow me routing to cell phones, and generally better voicemail notification. By putting in a Talkswitch with 9133i phones they kept their 4 line KSU model while gaining all the new abilities of a modern IP PBX.
