VoIP services offer many features.

We have identified multiple features, some of which are redundant (or go by different names depending on the provider).

Note that by hovering over the name of each feature on a provider's details page will bring up a tooltip that helps define the feature. To view which features are available under your desired plan, you will see either an 'X' or a checkmark next to the feature.

There is also a section denoted as 'Optional Feature Pricing', where extra features can be added on for the associated price.
