If you are looking to purchase a business phone system, one of your main considerations will be the average lifespan of the system. What I mean by this is, how long will it take before I have to upgrade or replace my systems?
Phone systems nowadays have an average lifespan of around 5-8 years, although many of them will continue to function properly (with regular maintenance and component replacement) for significantly longer periods of time. Often, phone systems can continue to function for several years after the “best before” date has passed, but there is a risk in continuing to use them for an extended period of time.
The most significant concern is that, no matter how much you manage to keep your phones together, they will ultimately fail to function properly.
For certain firms, their phone system is “mission essential,” which means that if they miss a call, it will have a negative impact on their whole business operations in one way or another. If this is the case for your company, you cannot afford to wait until your phone system has completely failed before upgrading.
Note however, that the lifespan of a business phone system is also directly related to how well the phone system is maintained. This means that while a well maintained phone can last for the maximum period, a poorly maintained one may fail long before then.
