PBX and Key/Hybrid System Comparison

PBX and Key/Hybrid Systems

PBX and Key systems are the wave of communication for business everywhere. The key
difference between PBX and Key/Hybrid systems are the amount of stations each can handle.
Key systems are designed for clients with very small line size requirements and very basic
needs. It usually handles between 16 to 48 stations. PBX systems on the other hand
handle a lot more stations as well as more features and sophistication. PBX are designed
for larger corporations and cost much more than a simple key system communication need.
Another key advantage of PBX system is it allows for room for corporation growth over the
years than that of a Key System or Hybrid system.
