A VoIP system will convert your analog voice signals into digital signals that are transmitted in real-time over your high-speed internet connection. In practice, it is not incredibly alien to previous setups: you can still use a desk phone in concert with a SIP (session initiation protocol) server. You can program the VoIP system to forward calls to the answering service, which will abide by the business rules you set up. For cellphone users, the same service is accessible through a VoIP app. In offices where connecting every phone via Ethernet cables is impractical, Wi-Fi options are viable thanks to advances in Wi-Fi speed.
Many top answering service companies, such as Answering Service Care, offer virtual receptionist services in parallel to their live answering service. This broadens the range of services that can be offered. Services include video call support, to improve customer experiences via better personal engagement, greater integration with universal communication tools in a variety of formats, and even automated call distribution, for larger enterprises that field a significant volume of client or customer calls.
