What is a VoIP call center?
A VoIP (Voice Over Internet Protocol) call center is a business call center service that uses an IP platform to handle calls from any number. All the service provider needs to do is install the system and connect the business to the internet, and the virtual call center can be put into operation.
The virtual call center service is set up by the business equipping itself with IP phones, or if using analog phones, they can utilize a connection to a VoIP Gateway device. Next, the service provider will deliver the software and configuration to connect to the company’s infrastructure. From there, the business can use the virtual call center freely without having to invest in a physical call center system, which is both expensive and cumbersome due to wiring.
