Still, COVID-19 won't last forever and hybrid work may not be right for your business, so keeping in mind core VoIP criteria is important. That means providing voice communications for employees at their desks once they start returning to the office. VoIP systems may also need to support a call center for sales or customer service and support; and they often need to connect with and through a host of other communications channels, such as conference calls, fax machines, mobile communications, text messaging, video conferencing, and wireless handsets.
YOD, or Bring Your Own Device, allows users to connect existing devices (smartphones, tablets, analog phones, desktop computers) to their virtual phone system, adding portability and eliminating the need to purchase an excessive amount of new equipment.

The auto attendant feature automatically redirects an incoming call to an extension without the need of a telephone operator, while audio conferencing lets multiple users join a single call. With ring groups, you can share the distribution of incoming calls among group members. As one of the best virtual phone service solutions, VirtualPBX provides ACD queues, an advanced version of ring groups, among its features. Given that it distributes calls to a group of users, this functionality makes managing a call center with large volumes of inbound calls much easier.
