A reliable business communication system is pivotal irrespective of different departments in a business. For example, sales require them to make and receive calls from prospective customers or associates. Marketing needs it for interdepartmental communication and reaching out to potential leads that are ready for marketing pitches. Customer support requires it for handling service requests and troubleshooting purposes. Traditional phone systems relied on physical telephone wires, and it poses multiple problems such as downtime due to weather conditions, the need for reliable telephone exchange, physical hardware for adding new extensions, etc.
