There are three pricing plans available at Grasshopper – Solo, Partner, and Small Business. All of these plans have all of the aforementioned features. They differ only in the number of phone numbers and extensions included. Grasshopper presents a pretty easy way to get a cheap virtual phone number.
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.

1. Thank Them or Apologize. The basic rule of thumb is that callers should hear one of two things when they first connect with your voicemail — either an apology for not being able to answer the call or a “thank you” for having called.
Ninja Number claims to be the world’s first artificial-intelligence powered virtual phone system. Some of the features are a bit different from competitive offerings so study them carefully. Plans start at $9.95/month for unlimited minutes. There’s also a “no credit card” free trial. Feature We Like: Offers a conversational interface to walk you through getting set up. Then the software evaluates your communication patterns and makes recommendations, including telling which calls you need to return.
