Company Description: Phone.com offers a feature-rich solution for small and mid-sized businesses. Their plans include more than 40 different standard features including custom phone numbers, video conferencing, user extensions, auto-receptionist, greetings, and call routing features. Each of their 40+ standard features are included in all of their plans, with their larger plans offering a few features that are typically geared toward larger enterprise businesses.
While many customers feel that 8x8 is a bit pricey, they've given positive feedback in terms of the company's quality features and customer service team.

Many of our users don’t need calls routed to their phone, they just want a good virtual voicemail system. We can do that, too. Just set up your VirtualPBX account with multiple voicemail boxes for each user or purpose you need. Furthermore, we can route calls directly to voicemail, without ringing a phone first.
Assessing the number and quality of features available can also staggering. We assumed you'll want the basics of call forwarding, voice mail boxes, and a standard menu that lets customers select where they want to direct their calls. But consider other features, like applications that will allow portability from business to cell phone, features that will translate voicemail to text or email, call recording, fax services, and even features that will work with Google documents, Salesforce, or your office software. How much of these additional features does your company really need, and how much are they worth to you?
