Let’s start from the beginning. Remember those days when a long distance call was incredibly expensive, and a call to a mobile would cost even more? Back in the day, telephone systems were run through an analogue network PSTN (Public Switched Telephone Network) and a digital network ISDN (Integrated Services Digital Network). While providers would charge exorbitant prices for this service, there was no space for flexibility or any control by the user. You need a new line? Great, an engineer will be with you as soon as they can – probably in about a month. One of your managers broke their leg and will be working from home? Bad news for their home phone bill. Disaster recovery? Lengthy, expensive, and that’s without even thinking about the loss of business while your phone lines are down.
Present day: VoIP
Fast forward a few decades and now you can use the internet to make phone calls. Traditional PSTN- and ISDN-based systems are still available, but the higher line rental costs are pushing IT managers to consider internet-based phone solutions (VoIP stands for Voice over Internet Protocol) that provide better value for money.
Voice over IP phone system has proved to be an infinitely more reliable and cheaper solution than the traditional ISDN lines. With this in mind, British Telecom (BT) announced in 2015 they will be switching off all the ISDNs by 2025, at which point everyone will need to be using a modern system. So rather than waiting until 2025 and finding yourself in a rush to sort out your phone system, start looking now, consider your options and start reaping the benefits of voice over IP for business sooner.
