Yealink IP Phones in a Network
Most Yealink phones are connected physically through a Category 5E (CAT5E) cable to a 10/100/1000Mbps Eth-
ernet LAN, and send and receive all data using the same packet-based technology. Some phones support the wire-
less network.
Since the IP phone is a data terminal, digitized audio being just another type of data from its perspective, the phone
is capable of vastly more than traditional business phones. Moreover, Yealink phones run the same protocols as
your office personal computer, which means that you can develop many innovative applications without resorting to
specialized technology.
There are many ways to set up a phone network using Yealink phones. The following shows an example of a net-
work setup:
