About This Guide
This guide is for personnel who administer AvayaAura™ Communication Manager, Avaya Aura
Communication Manager Branch (formerly known as Avaya Distributed Office), DHCP, HTTP/HTTPS
servers for Avaya 1600 Series IP Deskphones, a Local Area Network (LAN), or a Web server.

Introduction
4 1600 Series IP Deskphone Administrator Guide

Issue 6 August 2014 5
Chapter 2: Administration Overview and
Requirements
1600 Series IP Deskphones
The 1600 Series IP Deskphones currently support the H.323 signaling protocol.
The H.323 standard provides for real time audio, video, and data communications transmission over a
packet network. An H.323 deskphone protocol stack comprises several protocols:
●H.225 for registration, admission, status (RAS), and call signaling,
●H.245 for control signaling,
●Real Time Transfer Protocol (RTP), and
●Real Time Control Protocol (RTCP)
The parameters under which the 1600 Series IP Deskphones need to operate are summarized as
follows:
●Deskphone and System Administration on the Avaya Media Server, as covered in
Chapter 4: AvayaAura Communication Manager Administration.
●IP address management for the deskphone, as covered in DHCP and File Servers on page 37 for
dynamic addressing. For static addressing, see the Avaya 1600 Series IP Deskphones Installation
and Maintenance Guide.
●Tagging Control and VLAN administration for the deskphone, if appropriate, as covered in Chapter
7: Administering Deskphone Options.
●Quality of Service (QoS) administration for the deskphone, if appropriate. QoS is covered in
QoS on page 19 and QoS on page 28.
●Interface administration for the deskphone, as appropriate. Administer the deskphone to LAN
interface using the PHY1 parameter described in Chapter 3: Network Requirements. Administer

Parameter Data Precedence
Issue 6 August 2014 9
Parameter Data Precedence
If a given parameter is administered in multiple places, the last server to provide the parameter has
precedence. The precedence, from lowest to highest, is:
1. LLDP,
2. Manual administration, with the two exceptions described for the system parameter STATIC on
page 71,
3. DHCP,
4. HTTP/HTTPS script file,
5. theAvaya Media Server, and finally,
6. Backup files, if administered and if permitted.
Settings the IP deskphone receives from backup files or the media server overwrite any previous
settings, including manual settings. The only exception to this sequence is in the case of VLAN IDs. In
the case of VLAN IDs, LLDP settings of VLAN IDs are the absolute authority. Then the usual sequence
applies through HTTP/HTTPS.
Note:
Note: For the L2QVLAN and L2Q system values, LLDP settings of VLAN IDs are the absolute
authority only if the LLDP task receives the VLAN IDs before DHCP and HTTP, and the
DHCP client of the deskphone is activated at all. If the LLDP task receives the VLAN IDs
after DHCP negotiation, several criteria must be successful before the deskphone
accepts VLAN IDs from LLDP. For more information, see Link Layer Discovery Protocol
(LLDP).
The Administrative Process
The following list depicts administration for a typical 1600 Series IP Deskphone network. Your own
configuration might differ depending on the servers and system you have in place.
1. LAN and applicable servers administered to accept the deskphones.
2. Deskphone software downloaded from theAvaya support site.
3. 46xxsettings file updated with site-specific information, as applicable.
4. 1600 Series Deskphones installed. For more information, see the Avaya 1600 Series IP
Deskphones Installation and Maintenance Guide.
5. Individual 1600 Series IP Deskphones updated using local procedures, as applicable. For more
information, see “Local Administrative Procedures” in the Avaya 1600 Series IP Deskphones
Installation and Maintenance Guide.

Deskphone Initialization Process
Issue 6 August 2014 11
Note:
Note: The 1608/1608-I and 1616/1616-I deskphones support the Top Line Text and Audio
Push types (but not the WML Push type).
Deskphone Initialization Process
These steps offer a high-level description of the information exchanged when the deskphone initializes
and registers. This description assumes that all equipment is properly administered ahead of time.This
description can help you understand how the 1600 Series IP Deskphones relate to the routers and
servers in your network.
Step 1: Deskphone to Network
The deskphone is appropriately installed and powered. After a short initialization process, the
deskphone identifies the LAN speed and sends a message out into the network, identifying itself and
requesting further information. A router on the network receives and relays this message to the
appropriate DHCP server if the phone IP address is 0.0.0.0.

Step 2: DHCP Server to Deskphone
The DHCP file server provides information to the deskphone, as described in DHCP and File
Servers on page 37. Among other data passed to the deskphone is the IP address of the HTTP or
HTTPS server.
Step 3: Deskphone and File Server
The 1600 Series IP Deskphones can download script files and settings files from either an HTTP or
HTTPS server. These deskphones can also download the application files from the HTTP server. The
deskphone queries the file server, which transmits a script file to the deskphone. This script file, at a
minimum, tells the deskphone which application file the deskphone must use. The application file is the
software that has the telephony functionality.
The deskphone uses the script file to determine if it has the proper application file. If the deskphone
determines the proper application file is missing, the deskphone requests an application file download
from the HTTP server. The deskphone then downloads the file and conducts some checks to ensure
that the file was downloaded properly. If the deskphone determines it already has the proper file, the
deskphone proceeds as described in the next paragraph without downloading the application file again.
The deskphone checks and loads the application file, then uses the script file to look for a settings file,
if appropriate. The optional settings file can contain settings you have administered for any or all of the
1600 Series IP Deskphones in your network. For more information about this download process and
settings file, see Chapter 6: Deskphone Software and Application Files.
Step 4: Deskphone and the Call Server
The call server referred to in this step is the Avaya Media Server.
In this step, the deskphone might prompt the user for an extension and password. The deskphone uses
that information to exchange a series of messages with the call server. For a new installation and for full
service, the user can enter the deskphone extension and password. For a restart of an existing
installation, this information is already stored on the deskphone, but the user might have to confirm the
information. The deskphone and the call server exchange more messaging. The expected result is that
the deskphone is appropriately registered and call server data such as feature button assignments are
downloaded.

Error Conditions
Issue 6 August 2014 13
The 1600 Series IP Deskphones support a feature called Unnamed Registration. Unnamed
Registration allows a deskphone to register with the Avaya Media Server without an extension,
assuming theAvaya Media Server also supports this feature. To invoke Unnamed Registration, take no
action. Allow the Extension... prompt to display for 60 seconds without making an entry. The
deskphone automatically attempts to register by means of Unnamed Registration. A deskphone
registered with Unnamed Registration has the following characteristics:
●only one call appearance,
●no administrable features,
●can make only outgoing calls, subject to call server Class of Restriction/Class of Service
limitations, and
●can be converted to normal “named” registration by the user entering a valid extension and
password (that is, logging in).
Note:
Note: Unnamed Registration requires administration on the AvayaAura Communication
Manager system.
You can also administer the deskphone to avoid unnamed registration and remain unregistered if no
extension and password are provided. For more information, see UNNAMEDSTAT in Table 9.
For more information about the installation process, see the Avaya 1600 Series IP Deskphones
Installation and Maintenance Guide.
Error Conditions
Assuming proper administration, most of the problems reported by deskphone users are likely to be
LAN-based. Quality of Service, server administration, and other issues can impact user perception of
IP deskphone performance.
