EDUbrief: Selecting VoIP Phones

An IP phone uses voice over IP technologies for placing calls connected to an IP network. This could be the Internet or a local area network. This is an alternative to connecting to the public switched telephone network, the PSTN. The primary difference among the voice over IP phones is the signaling protocol that is used. The session initiation protocol known as SIP is a standard that many providers and vendors support. But there also IP phones on the market that support the standard H. 323, Cisco’s skinny protocol, and other proprietary protocols.

In this EDUbrief you will learn:

-IP vs. SIP phones

-Interoperability and compatibility

-Power over Ethernet (PoE)

-IP phone connection configurations

-Selection criteria
