Wireless - Avaya IP DECT

Note: While still supported on IP Office release 6 and available for upgrades, we strongly suggest to use DECT R4 for new installs.

The IP DECT 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 IP DECT solution radio fixed part (RFP) or base station connects to the IP Office using an IP protocol based on H.323.

The Avaya IP DECT solution 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 indoor base station can also optionally be connected to main power via an external power adaptor. Each outdoor base station can only be powered using PoE - no individual power supplies are available to power the outdoor IP DECT base station.

In EMEA and APAC this system supports the 3701 and 3711 handsets.

In North America, only the 3711 handset is supported.

Note: The regulatory requirements for the radio part (base station and Handset) are slightly different in the US and Canada compared to EMEA and APAC. Therefore, while providing the same functionality, the hardware is different in these two regions.

Each Base station has the following features:

8 simultaneous Voice and up to 12 Signaling Channels.
Codec G.711, G.723, G.729 for base station IP trunk connection.
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.  

 

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:

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. DECT handsets must NOT be configured into collective groups.
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. In North America this functionality became available in Release 4.0.7.

 

Avaya IP DECT System licensing

A license is necessary for this functionality. This license is called the Avaya IP Office IP DECT Mobility Manager license. This license is entered through the main base station (ADMM) and is NOT entered through the IP Office System manager. A feature key server is NOT necessary to enable the IP DECT functionality.

No separate PC or software is required with this system.

In all regions, a "plug and play" licensing mechanism is available: It consists of a pre-licensed and ready to go two-base-station bundle ("IP DECT IPO STARTER KIT ") and two pre-licensed base stations ("IP DECT RFP32/34 UPG KIT" ) that can be added to the system independent of the number of licenses in ADMM. This allows easier deployment and upgrades of systems without the need to buy a separate upgrade-license. For IP Office we recommend to use the "Starter Kits" and the "Upgrade Kits" for new installations for added flexibility and to minimize the installation effort.

The bundles that have previously been available in EMEA will continue to be available and are compatible with the pre-licensed base stations described above, if the latest software is installed on the IP-DECT system, e.g. upgrade an existing 5-base-station system with an "Upgrade-Kit" when adding an extra base-station instead of upgrading the system-license to a 6+ license.

Additional upgrade licenses will continue to be available for systems that need to expand their current coverage or capacity.
