The Avaya 4600 Series IP Telephones deliver an extensive set of software features, high audio quality, and attractive streamlined design.
Avaya 4600 Series IP Telephones are simple to use with both fixed and flexible feature buttons, easy-to-read graphics including back lighting and color displays on some models, and several wall mount and desk mount options. They have been optimized for reliable use in IP networks, with sophisticated security capabilities such as media encryption and protection from denial of service attacks. Built-in Ethernet switch ports enable streamlined desktop implementations, while voice packets are tagged with the appropriate quality of service (QoS) parameters such as 802.1q and DiffServ for priority treatment by QoS-enabled IP networks. For those environments requiring Gigabit Ethernet, a GigE adapter for 4600 series is now available. The 4600 Series IP Telephones also support the 802.3af power over Ethernet standard.
Avaya 4600 Series phones support an integrated VPN client installed within the telephones themselves. Making it easy to deploy high quality telephony to teleworkers, home agents and to workers in disaster recovery scenarios.
For customer environments requiring Gigabit Ethernet support, a Gigabit Ethernet adapter is available - providing 10/100/1000 Mbps support for both the 4600 series phone and co-located laptop or PC.
Advanced web-enabled graphical displays on the 4610SW, 4620SW, 4621SW, 4622SW, 4625SW and 4630SW versions support browser-based desktop applications such as online order entry and inventory lookup in addition to more traditional voice applications such as directory-based dialing and call logging. The 4610SW, 4620SW 4621SW, 4622SW, 4625SW IP Telephones have additional application functionality. Push of audio and textual alerts to the phones is now supported through the application programming interfaces (APIs) on these phones. The Avaya Phone Application Suite includes a set of pre-packaged phone applications for use on the 4610, 4620, 4621, 4622, and 4625. Please refer to the Phone Application Suite section on avaya.com for more details.
As a key component of the Avaya SIP Enablement Services (SES) Solution, the 4600 Series Telephones provide best in class SIP Telephony capabilities.
The 4621SW IP Telephone is based on the 4620SW with the same housing, feature buttons and software along with an enhanced backlit display. The 4621SW also supports the new EU24BL (backlit expansion module) and also includes a 2 port Ethernet switch. A new phone, the 4621SW will replace the 4620SW. The 4621SW can run either the H.323 protocol, for integration with traditional Avaya IP Telephony Servers and Gateways, or the SIP protocol, for support of SIP Communications Servers such as the Avaya SIP Enablement Services (SES) Rel 3.0 Solution.
