Avaya DECT R4

The Avaya DECT R4 solution delivers the productivity-boosting benefits of IP and wireless communications across multiple offices in a convenient, lightweight handset. It provides businesses with a highly functional wireless solution with the ability to scale to support large numbers of users. This system also supports users in different offices connected via a WAN. The Avaya DECT R4 solution radio fixed part or IP base station (IPBS) connects to the IP Office using an IP protocol based on H.323.

Avaya’s DECT R4 solution features all advantages of a full blown DECT solution for the enterprise market: Cost effective high wireless voice quality in a frequency band exclusively reserved for DECT that is secure, easy to deploy and enhance.

The solution consists of:

  • Two wireless handsets
  • Two radio base stations (with internal and external antennas) with IP interface for usage with IP Office
  • A 4-channel Compact base-station for small installs, up to 5 can be used per system.
  • An appliance server for centralized functions like corporate directory and internal phonebook access, simple text messaging, integration of messaging and other external applications, centralized configuration and maintenance etc.

As the solution contains a handset with liquid protection and BlueTooth headset interface and an appliance server for attaching messaging applications it is especially well suited for verticals like healthcare and retail.

The Avaya DECT R4 solution on IP Office supports up to 120 handsets and 32 base stations. Each base station can be powered over the LAN using the Power over Ethernet (PoE) standard. Each base station can be also powered by an external power supply. There are two versions of the base station (IPBS) available:, a standard base station with fixed antennas and an enhanced base station with a variety of external antennas. Both base-stations can be installed in an outdoor housing to provide an “external” base-station.

DECT Feature Overview

Given the degree of integration available to wireless users with DECT, there are a variety of means by which calls can be routed to wireless handsets:

  • Handover
    While in motion, the handset performs continuous measurements to determine which IP DECT base station has the strongest signal. The one that can be best received is defined as the active Base station. To prevent the handset from rapidly switching back and forth between two base stations that are equally well received, threshold values are used. Handover between base stations occurs seamlessly whether a call is active or not.
  • DECT Networking
    An IP DECT telephone can travel from one office to another which is connected over a wide area network (WAN) link and make and take calls. In this scenario the main IP DECT controller remains at one “headquarters” location, with slave base stations in up to 31 other offices.
  • DDI/DID
    Since each wireless handset is an extension on the IP Office system calls may be routed directly using a DDI/DID number.
  • Transfer
    Calls may be transferred to DECT extensions by operators or other extension users and DECT extension users may transfer callers to any other extension user.
  • Hunt Group compatibility
    Wireless handsets may be programmed as members of groups and answer calls in the same manner as any other extension within that group.
  • Group working
    Wireless handsets may be programmed as members of groups and attract calls in the same manner as any other extension within that group.
  • Divert destination
    Users may initiate any or all diverts from an Avaya desk phone to a wireless handset.
  • Twinning
    Twinning allows calls to a user main extension number to alert at both that extension and a secondary extension. Though not restricted to DECT, this feature is aimed primarily at users who have both a desk phone and a wireless extension. Calls from the secondary twinned extension are presented as if from the users main extension. Presentation of call waiting and busy is based on whether either of the twinned extensions is in use.

Overview Avaya IP Office Wireless VoIP

The Avaya IP Wireless solution offers an advanced Voice over IP (VoIP) client for wireless networks. This solution allows SME’s to take advantage of the cost savings and simplified management of a converged voice and data infrastructure.

Both the Avaya 3641 and 3645 phones are optimized for Avaya IP telephony and emulate the wired 4606 IP Telephone. They work in conjunction with the Avaya Voice Priority Processor to ensure voice quality over Wireless LANs. They are field upgradeable through an integrated TFTP client, so telephones can be updated with new protocols, features, and capabilities as they become available.

Based on global standards for wireless LAN’s, the Avaya IP Wireless Telephone Solution simplifies network infrastructure by enabling voice traffic to be carried along with data traffic over the same wireless network. Both the 3641 and 3645 telephones are available for direct sequence 802.11b Wi-Fi networks. The SpectraLink Voice Priority (SVP) quality of service protocol is simple to implement and reduces packet queuing delays for voice traffic.

SpectraLink Voice Priority-enabled access points are available from the leading providers of enterprise wireless networks such as Avaya.
