Avaya IP Office SIP-DECT

7 techniques to implement and maintain the Avaya D100s.

By the end of this post, ‘Avaya IP Office SIP-DECT,’ you get learn the 7 techniques I use whenever I implement the Avaya D100 base units, in conjunction with the SIP-DECT D160 handsets, environmental requirements, components, best case-scenarios for connectivity, and access-point placement.

Sometime this past spring, I was helping a customer implementing a couple of cordless handsets for their warehouse personnel. Equipped with portable phones, they can perform day-to-day call-handling tasks, making their job easier.

The following 7 techniques can help you implement the D100 SIP-DECT solution

• 1.- Getting Started
• 2.- File Delivery
• 3.- SIP-DECT Line configuration
• 4.- Initial D100 Setup
• 5.- Manual Configuration
• 6.- Handset Registration
• 7.- Registration Process

1.- Getting Started

Before you start installing the base units, antennas, and repeaters, you have to perform a site survey to understand the building layout and structure. Besides the site survey, you also have to know the cabling infrastructure, and wireless components that are already installed, especially ensuring that the SIP-DECT-RF Spectrum is not overloaded.

Site Survey – Building Layout – The building structure, corners, building-extensions, and multiple floors are your main focus when performing the site survey.

Building Structure – Walls and ceiling types are the two major factors here. Sheetrock / Plaster Walls, Brick, Cinderblock, Firewalls, and Wood are the most common types.

Multiple floors – My best advice is to run a cable (uplink) from the IP Office (PBX) to where the antenna is, and stay away from staircases due to the fact that they are normally located in one side of the floor limiting the signal or coverage. As a workaround, you might be able to install a repeater inside the staircase between the floors, and a second repeater around 17 feet away.

Warehouse environment – Metal beams / Metal-sheets, columns, and other wireless transmitters are the usual suspects to provoke the signal to diminish.

Yards and open areas – If you have customers working in a yard, the best solution is to install the repeater or antennas toward the center of the warehouse ceiling pointing straight over where they will be using the handsets.

SIP-DECT Site Survey with the D160- If you can’t afford a wireless kit, use the D160 RSSI (Received Signal Strength Indicator) measurements to analyze the wireless attenuation or gain, which is measured in dBm (decibels – milliwatts). Avaya recommends that the reading should be around -60 dBm for good speech quality.

Connectivity – PoE is needed to power the D100 base-unit. The Ethernet wiring rules apply when installing the CAT5/6 cabling for the D100, as well as VLANs, and other network considerations.

2.- File Delivery

An HTTP Server is needed in order to serve the necessary files to upgrade the D100 base-units. The IP500V2 can be utilized to provide these files, as well as the DCHP server for the base-unit.

The files are delivered in this order=

D100.cfg tells the D100 base unit to download first the D100Settings.txt file, then the D100_BS_MS_x_x_x.bin, and lastly the D100_BS_LS_x_x_x.bin files.

Files and their analogy

D100Settings.txt – It sets the DSCP QoS DiffServ values, Server UDP and TCP ports = 5060, among other settings.

D100prov.txt – This file is auto-generated by the IP Office when it first detects a D100.

D100_BS_MS_x_x_x.bin – Firmware

D100_BS_SL_x_x_x.bin – Firmware

The best way to find and test the HTTP Server is by opening your internet browser and navigate to the IP Office IP address and type the file name. e.g. = 192.168.42.1/D100settings.txt

3.- SIP-DECT Line Configuration

Before you start configuring the IP Office system, there are a couple of things that you have to iron out. I have listed some here=

Voice Compression Channels or VCMs – These are required to initiate or carry the VoIP to tdm voice transmission and vice-versa. When using Direct Media Path you will not use the VCM channel, but in most instances it is needed for call setup, then the VCM gets released when the call has been established.

Licensing –  IP-Endpoint licenses are required.

SIP Registrar – Because the D100 is a SIP-Endpoint, you must enable the SIP registrar through the IP Office LAN VoIP configuration.

The SIP-DECT Line – Allows the D160 connect through the SIP Registrar,  it authenticates the extension line association, and utilizes the IP Office telephony features and functionalities.

System Configuration

Create the SIP-DECT=

Line – Assign a unique name, enter the MAC address, select ‘Configure Base IP’, and decide if DHCP will be implemented. For static configuration unselect the DHCP option, fill out the fields required and choose your provisioning interface (LAN1 or LAN2 IP Address). The VoIP stays the same.

Extension – Leave the ID as is, assign the base-extension ID, and select the SIP-DECT Line from the SIP DECT Base. If there is only one line in the system it should populate on its own. Once you have completed, press the “OK” radio button, and click on “Yes” when the pop-up window asks if you wish to create an associated user.

User Configuration – Here, you will give it a unique name, and assign a login code (User/Telephony/Supervisor Settings/Login Code) to allow the D160 use the login feature.

4.- Initial D100 Setup

Here, I’ll walk you through the initial IP Addressing assignments.

Record the MAC -Before you start configuring the D100, it is a good practice to record the MAC address. In some cases, the OUI (Organizationally Unique Identifier) comes up with the 00e011 which belongs to Uniden Corporation.

Connect via the Web-browser by entering the IP Address shown in the Monitor trace. If by any chance you have difficulties identifying the IP Address of the D100, there are two other options that you use.

5.- Manual Configuration

The best way to configure the D100 is through the web-interface is accessing it through the IP Address obtained from the IP Office, but you can also access it through its default IP Address of 192.168.1.100 by pressing the Registration and Reset buttons for a couple of seconds until the LEDs start flashing.

Web-configuration – Now that you are able to ping the 192.168.1.100 ip address, open your browser of choice and enter d100/d100 as the login and password. Once connected navigate to the Configuration parameters window to configure static IP Address settings.

6.- Handset registration and configuration

Handset Registration – Press the Registration option while searching for the base-unit. Once connected, you must enter the base-unit’s pin 3100, enter the extension of the D160.

An alternative is to go through SSA and select the D100 allowing registration should force the D160 to enter a the pin (3100)

Re-registration – select the Config option and enter the password 7828876 (QUATTRO), then select

Handset IP Configuration – There will be times when he D100 base unit won’t be able to communicate with the SIP Registrar (IP Office). Utilizing the D160 handset (registered to the base-unit), go to the configuration option, then select “Network,” this will show the existing IP Address of the D100. Here, you can also update the IP Address.

7.- Understand the D100 registration process

Once you have connected the D100 Base-unit to the network, it will broadcast with a ‘whois’ packet through the entire network, and because the IP Office serves as a BooPT server, it captures the request as a L2 Frame, which contains the D100’s MAC Address of 00E011XXXXXX.

The Control Unit will auto-generate and prepare the files based on the request. There are a couple of L2 frames interchanged before all the magic begins. A TFTP RRQ (Read Request) will be sent back to the D100 to alert it that things are getting prepared at home, then a TFTP WRQ is processed by the IP Office.

The D100 will request the files in this order=

• D100.CFG
• D100prov.txt
• D100settings.txt
• D100_BS_MS
• D100_BS_SL
• Languages

Because the D160 is a SIP User and the IP Office the SIP Registrar, a database will be auto-created based on the UA information. Let’s say that we have a SIP extension 201, the system will auto-create a file= D160_201@192.168.42.1.cfg and store in the system\primary\sipusers directory.

Authentication method – Under the system/primary directory, there is a file called ‘D160_201@192.168.42.1.keys’ which is used as a token to allow the D160 Cordless handset access to the system, and interchange the SIP Methods and allow it for call control, and other telephony features.

Question -What issues do you normally experience when deploying the D100 with D160s?

TFTPReceiver Unreachable  – Keep in mind that the SIP-DECT Line, IP Routes, VLANs, and in some cases Firewalls, are responsible for the network communication between the IP Office and the D100. In my case, the MAC Address was not entered under the SIP-DECT line.

I have provided some images for you to compare=

Check the license files

Enable the IP Office SIP Registrar

Create the SIP-DECT Line

Name it, and enter the MAC Address of the D100. Select the Configure Base IP, then DHCP or static configuration. Set the provisioning IP Interface of the Gatekeeper (IP Office)

Create a new SIP-DECT extension

Once you press the OK button, the system will send you to the a new user form where you will create a new user, fill out the normal fields, then head over to the Telephony/Supervisor Settings, and create a login code.
