Provides highest audio quality for optimum flexibility for end users.

Comprehensive Functions and Capabilities

Avaya 4600 Series IP Telephones provide the same advanced calling features and functions as traditional Avaya telephones. These stylish phones incorporate a number of convenient features, such as a message waiting indicator, easily readable displays, hearing aid compatibility, NetMeeting compatibility, multiple programmable feature keys and display navigation keys.
There is no need to retrain people to use Avaya IP Telephones, because they use the same familiar operations as other Avaya phones.

Simplified Wiring with a Single 10/100BASE-T Ethernet LAN Connection

An Ethernet connection built into each phone (except the 4601 and 4602) enables users to connect a desktop computer to their LAN by plugging it directly into the phone, without needing a separate computer connection in the wall. The 4602SW, 4610SW, 4620, 4620SW, 4621SW, 4622SW 4625SW and 4630SW come with an integrated switch.
Helps reduce wiring and installation costs. The wiring can be further simplified by using the available 802.3af-based Power over Ethernet capability to deliver power to the phone over the LAN, rather than using a wall plug.

Industry-standard Protocol Support

Avaya IP Telephones operate with industry-standard protocols and advanced software, including the H.323 and SIP protocols for voice communication over an Internet Protocol network, G.711, G.729A/B and G.726A voice codecs and a variety of Quality of Service capabilities. Those include UDP Port selection at Layer 4, Diffserv priority numbering at Layer 3, and 802.1p/q at Layer 2. Avaya IP telephones also support the 802.3af Power over Ethernet standard.
Delivers high-quality features based upon industry standards, rather than proprietary solutions, for better interoperability.

Simplified Software Provisioning

End users can access IP Telephone software upgrades and enhancements on the Avaya Support Web site. For example, SIP software for the Avaya 4602/4602SW can be downloaded from this site to a TFTP server for enterprise-wide provisioning. New releases of software are provisioned in this manner.
Simple, centralized software provisioning can help reduce implementation and maintenance expense.

Web Browser, Local Speed Dial, and Call Log Applications

The 4610SW, 4620, 4620SW, 4621SW, 4622SW, 4625SW and 4630SW support local call log, local speed dial and web browser applications.
Access to web-based applications and information as well as the added efficiencies of speed dials and call logs stored in the telephone.

Push of Content

With Release 2.1 of the 46xx Series IP Telephone firmware (which applies to the 4610SW, 4620SW, 4621SW, 4622SW, and 4625SW telephones), comes support for a new feature called "push". "Push" is the capability of an application using the WML protocol to send content to the telephone without the user requesting it, and (potentially) overriding what the user is otherwise experiencing. This capability is being made available to 3rd-party developers through Software Developer Kits (SDKs). Content can be pushed to the phones via a text message, WML web page, or an audio stream through the handset or speaker.
IP telephones become applications-enabled appliances instead of just phones. The addition of push enables phone displays and/or audio to support a variety of applications (web browsing, time reporting, emergency alerts, travel reservations, account code entry,  announcements, branding via screensaver, inventory lookups, scheduling, etc).

Avaya Phone Application Suite

Initially supported on the 4610SW and 4620SW, Avaya Phone Application Suite consists of a pre-packaged set of productivity enhancing phone applications.  These applications are easy to deploy and leverage the large, bright displays and embedded micro browsers on the Avaya IP telephones.

The Avaya Phone Productivity Pack includes the following applications:
  • Broadcast Server: allows for text, graphics, and audio message broadcast to the displays and speakers of IP phones within a location.  Great for simple reminders or alert messages such as an email server being taken temporarily off line
  • Text Messaging: provides simple SMS text messages between IP phone users

Backlit and color display options

The display area is large, bright and colorful.

Backlit displays make viewing easier. The 4600 series of IP phones are designed and optimized for the delivery of content and applications directly to the phone.

Investment Protection - SIP migrations

As a key component of the Avaya SIP Enablement Services (SES) Solution, the 4600 series of telephones equipped with SIP firmware provide superior SIP telephony capabilities.
Future investment protection is simple.  4600 Series Telephones in H.323 mode are migrated to SIP via a simple, free, firmware download.
