You can choose a one- or two-year plan. If you sign a two-year contract, 8x8 will give you free IP phones. You receive one free phone per extension. If you already have a telephone number, you can keep that same number under an 8x8 contract.

You can include up to 20 participants in a conference call. You can also perform standard phone operations such as call waiting, caller ID blocking, call park, call recording and do not disturb. This business VoIP integrates with Outlook, Salesforce and SugarCRM, among other applications. This service lacks many advanced queuing options, however they do offer called call ring groups to handle excess calls. When there are more people calling in than employees to answer the phones, the system stacks the calls until one of your employees can take the next call.
