SIP Phone

A SIP phone uses Session Initiation Protocol (SIP) to initiate, manage and terminate voice communications sent and received as data packets via the internet. As a Voice over Internet Protocol (VoIP) solution, SIP phone users can often call other SIP, IP, internet and VoIP users for free, and call at low rates to landline and mobile phone numbers on the Public Switched Telephone Network (PSTN).
