Figure 52: Avaya 4630 IP Screenphone
The IP Telephone is a physical voice terminal that provides IP Telephony. Avaya IP Telephones
bring the rich features and functions of Avaya Communication Manager directly to the desktop.
They are an essential part of converged voice and data networks that are built with the Avaya
Application Solutions components. These telephones deliver an extensive set of features, high
audio quality, and have an attractive streamlined design.
The 4600 Series IP Telephone sets (or terminals) are a product platform of terminals that
support Avaya Application Solutions. The sets operate and function similar to the 6400 series
Digital Communications Protocol (DCP) terminals when connected to the Avaya servers with
Avaya Communication Manager, but provide added functions that are not possible within the
digital terminal product line.
Networking coordination
The IP terminals use the Internet Protocol to communicate with the systems to which they are
attached. The protocol is H.323 with proprietary signaling added to provide access to the full
functionality that is available in the Avaya servers running Avaya Communication Manager.
IP Telephones are intended to connect to the customer's data network. These networks
inherently contain products from many different vendors, and thus are less controlled than
circuit switched networks. Therefore a Network Assessment is recommended as outlined in
Network assessment
The 4600 series voice terminals cannot be connected directly to the Public Switched Telephone
Network (PSTN). They can only be connected to an Ethernet-based IP network. Therefore,
network connection issues related to direct connection to the PSTN do not apply.
The IP Telephones provide connectivity to multiple external devices through a single Ethernet
connection. The telephones contain an integrated switch or hub to connect the user's PC to the
network through the telephone, thus requiring only a single Ethernet connection for both
devices.
