Compare VoIP Provider Features

VoIP Comparison is a critical activity to perform prior to selecting a Business VoIP provider. If you have ever tried comparing VoIP providers, you likely have an appreciation of how tough a job it is to perform a comparison that actually yields useful results. Here are just a few reasons why a VoIP comparison is so difficult:

Pricing: Often tiered based on number of user seats requried. Not always cleared stated and instead vague statements are made such as "From $XX.YY per month".

Features: Different terminology is often used by different providers to describe the same feature. No clear statements made on unsupported features.

Add-ons: Information on additional costs for "premium" features is often hard to find.

Support: Information on the customer service and support hours and ways to connect is not always available.

Side-by-side Comparison

WhichVoIP has made this job much easier for you, allowing you to perform a true apples-for-apples comparison using our VoIP comparison tool. We believe this is one of the most powerful tools on the market today for VoIP comparison shopping and we hope you find it useful.
