Smaller office applications are those with typically fewer than 8-12 people. They generally have 3-6 analog phone lines. There is usually one phone for each employee that is trained to place and receive calls. Small offices are well served by our entry-level, KX-TA824 analog system when the need is for basic features or the KX-TDA50 on the more feature-rich side. One point to remember is that if you require an automated attendant and if any of your choices (Sales, Tech Support, Shipping, etc.) require more than 1 phone to ring at once, you are already past the capabilities of the KX-TA824. Focus on a KX-TDA50G or higher.
