Whoever said "if it isn't broken, don't fix it" wasn't talking about an outdated TDM phone system.
Sure, your TDM (Time Division Multiplexers) PBX may be working today. But will that be the case tomorrow?
There's any number of factors that can cause an old-school telephone system to fail when you need it most. They include damage to the equipment on premises, power problems at your site, cut cables in the phone room by phone company techs, or parts that fail because of length of time they've been in use.

Few organizations can afford the risks to their reputation associated with something that usually "just works". You wouldn't hire a customer service representative who only occasionally answers their phone. You can't afford to sell a product that is good some of the time.
