What is a SIP Phone?


An IP phone uses Voice over Internet technologies allowing telephone calls to be made over an IP network such as the Internet instead of the ordinary PSTN system. Calls can made over the Internet or over a private IP Network. The phones use Session Initiation Protocol (SIP). An IP phone can be a software based softphone or a purpose built hardware device that looks and operates like an ordinary telephone or cordless phone.
