Telephony via the Internet Protocol

VoIP phones, also known as IP phones, offer capabilities not available in analog phones, as well as additional needs since calls are distributed through the internet rather than the public switched telephone network (PSTN).

A VoIP phone is a software or hardware-based phone that uses Voice over IP Technology to accept and transmit calls over IP networks.
VoIP phones transform analog technology to digital, which is then transported over the internet and changed into income digital phone signals, which are finally converted into telephone audio.

Telephone System Using VoIP

There is a variety of Voice Over Internet Protocol phones on the market, with some requiring an A/C adaptor and others requiring Power Over Ethernet. My Ethernet cable provides power to the phone instead of an A/C adapter, thus there will be no need to install or remove the adapter.

IP Phones Workflow: To connect to the internet and use the IP Phone’s audio calling functions, you’ll need a few things. The Dynamic Host Configuration Protocol (DHCP) is used to assign IP addresses to phones, as it automatically configures the network and VoIP phone characteristics. In this perspective, a Dynamic Name System tracks IP addresses to allow devices to communicate with one another. A protocol is also used to establish the bandwidth available for calling services.

Session initiation protocol, a real-time Transport Protocol that receives and sends different media information, is another VoIP Phone protocol that is often used as an alternative to H.323. RTP, STP, or H.323 are used for multimedia content on the Voice Over Internet Protocol Phone.
