Do you have a phone system that is sitting in your back office that has been bolted to the wall for the last 10 to 15 years? Or are you using a key system that isn’t providing you the functionality your employees need? Most old small business PBX’s are extremely reliable, they are built like tanks, and frankly just keep working. If you are like me (and I am a small business owner), you don’t look around in your office trying to replace business equipment that is still working. If your PBX is operating just like it did on the first day you turned it on, why replace it? Why invest your valuable cash on a new phone system?
