IP phones have many features that are similar to traditional phones, such as the ability to place and receive calls, caller ID, call waiting, voicemail, and so on. In addition, IP phones often have additional features that are not available on traditional phones, such as the ability to view the caller’s IP address, the ability to transfer files, and the ability to place calls over the Internet.

IP phones are typically connected to a VoIP network, which is a type of network that uses the Internet Protocol for voice communications. VoIP networks can be either private or public. Private VoIP networks are typically used by businesses, while public VoIP networks are typically used by service providers.
