What is an IVR phone system?Short for interactive voice response, IVR phone systems gather information from callers by giving them choices in a pre-recorded menu. You’ve probably encountered them when calling a restaurant to make a reservation, or any other sort of customer support that involved calling. Depending on the number you press on the keypad, your call is then routed to the correct agent to help you out with your query. In other words, it’s a way to connect your callers to the agent that will be able to best answer their questions. What are the benefits of a call centre phone system?Keeps your customers happy – When customers give your business a call, they expect their query to be handled quickly and seamlessly. A powerful IVR phone system that can assign the right calls to the right agents will ensure your customers can hang up – rather than slam down – the phone, feeling satisfied with your service.Boosts efficiency – Whether you’re running a small or big business, your call centre is likely to experience a large number of inbound calls. Therefore, streamlining your service is key. IVR systems allow you to track all call activity in a single place, making it simple to understand where you’re faltering in customer service. Did you know that IVR phone systems can help reduce telephony-related costs by 30%?Scale up your business – The perfect fertiliser for growing your business is slashing costs and planting an infrastructure that’ll make your agents as productive as they can be. Call centre phone systems can do just that. They can also help you collect data to understand how your product is performing, and where it needs improvement. In fact, call centre phone systems can reduce your IT costs by up to 14%. What kind of call centre hardware do I need?To provide a high-quality customer experience, each of your agents will require hardware equipment, including a computer, headset, and high-speed internet connection. As for the software tools, you will need a call centre phone system, a customer relationship management (CRM) system, and workforce management tools.Here is why you need them:Hardware equipment (£900+ per workstation)Computer – to access your call centre software and other tools.Headset (headphones and microphone set) – having a comfortable and reliable headset with a noise-cancelling feature will facilitate clear communication between your agent and the customer.Internet connection – you’ll need strong bandwidth to ensure smooth communication, high-quality calls, and uninterruptible service.Software tools (£3,000+ per year)Call centre phone system – whether cloud-based or on-premise, a call centre software is your agents' main tool to manage all your customers interaction.Customer relationship management (CRM) system – a database typically integrated to your call centre phone system, which stores important customer information, such as client demographics, call logs, and purchase history.Workforce management tools – a software that helps you manage your workforce to make sure you have enough call centre agents to handle high call volumes, such as customisable SLAs and call monitoring.
