Introduction

Nortel* is pleased to announce the availability of UNIStim firmware version 0621C4P for the
IP Phone 2007. In addition, Nortel is pleased to announce the availability of firmware version
0623C4I, 0624C4I, 0625C4I and 0627C4I for the IP Phone 1110, IP Phone 1120E, IP
Phone 1140E and IP Phone 1150E respectively.

These new firmware loads deliver enhancements to Nortel’s IP Telephony Solution and
deliver general quality improvements. The enhancements available include:

 IP Client registration to Application Gateway 1000 and Application Gateway 2000

release 6.2 via cookies

Enhancements

Application Gateway New Set Registration Model using Cookies (Applies to IP Phone 2007,
1110, 1120E, 1140E and 1150E)

Application Gateway releases prior to 6.2 obtained phone DN to IP mapping information
from the Communication Server 1000 via a connection to the administrative console port.
With firmware releases 0621C4P, 0624C4I, 0625C4I and 0627C4I the Application Gateway
Release 6.2 can obtain the DN to IP mapping information, as well as other information,
directly from the Nortel IP phones via a cookie. Support for the cookie feature requires that
the Application Gateway and IP Phones be running in either a Communication Server 1000
Release 5 or greater environment, or a Communication Servers 2100 Release 10
environment. A major benefit of the cookie feature is the more effective transfer of phone
specific data from the communication server to a connected Application Gateway via the
respective IP Phone.

Quality Improvements

The 0621C4P, 0623C4I, 0624C4I, 0625C4I and 0627C4I firmware loads also continue to
improve the overall quality of the IP Phone 2007 and Next Generation IP Phones (1110,
1120E, 1140E and 1150E) through the delivery of ongoing resolution of CRs and closed
cases. In total, well over 100 quality improvements have been delivered, and 15 customer
cases have been closed in these new firmware loads since the last suite of GA firmware
loads. The list of closed cases since the last suite of generally available (GA) firmware loads
are listed below.

The 0621C4P, 0623C4I, 0624C4I, 0625C4I and 0627C4I firmware releases close the
following cases:

Product Advisements

Running Auto-VLAN on the IP Phones without the DHCP server offering VLAN
information may result in the IP Phone becoming unresponsive. (Applies to IP
Phone 2001, 2002, 2004, 2007, 1110, 1120E, 1140E, 1150E)

An issue was found with the Auto-VLAN feature in the IP Phones that could result in the IP
Phone becoming unresponsive. If the IP Phone is provisioned for Auto-VLAN and the DHCP
server does not provide VLAN configuration information, the IP Phone will attempt a
connection to the call server with untagged packets (i.e. no VLAN). If the phone cannot
establish connection to the call server, the phone will remain in an unresponsive state until
manually reset.

It is therefore strongly recommended that if the phone is provisioned for Auto-VLAN that one
ensures VLAN configuration information is provided in the VLAN-A option of the DHCP
packet.

A fix for this issue is currently being implemented and will be available in the next UNIStim
firmware release.

2-Step Upgrade May Be Required (Applies to IP Phone 1120E and 1140E)

One important note when upgrading the IP Phone 1120E to 0624C4I or the IP Phone 1140E
to 0625C4I from any load previous to 0624C1B or 0625C1B respectively, is that a 2-step
upgrade will be required. The IP Phone 1120E and 1140E cannot be upgraded directly to
the newly released firmware if they are currently running firmware previous to 0624C1B and
0625C1B respectively. Instead, the phones must first be upgraded to 0624C1B and
0625C1B or newer (recommend 0624C3C and 0625C3C). Once the phones are running at
least 0624C1B and 0625C1B firmware, they will accept being upgraded to 0624C4I and
0625C4I respectively.

Network Loop (Applies to IP Phone 2007, 1120E, 1140E)

These firmware releases include a fix to help prevent network loop scenarios from being
introduced into the network, and the resultant network outages that can occur. The network
loop avoidance fix was first introduced in 0621C2B, 0624C1E and 0625C1E. One important
note when upgrading to 0621C4P, 0624C4I or 0625C4I from any load previous to 0604D9H,
0621C2B, 0624C1E or 0625C1E respectively, is that IP Phones that were inadvertently mis­wired during initial installation will not be allowed to work until the cabling problem is
corrected. This fix is only an issue if the installer, when installing the Nortel IP Phone 2007,
1120E or 1140E, inadvertently connected the network Ethernet cable to the PC Ethernet
port on the back of the phone, instead of connecting it to the network Ethernet port on the
back of the phone. IP Phones 2007 running firmware previous to 0621C2B and IP Phone

1120E and 1140E running firmware previous to 0624C1C and 0625C1C respectively will
work when incorrectly connected, but this does introduce the potential for network
degradation. These new firmware loads will try and safe guard the network by trying to
prevent phones that are mis-cabled to function. This means that the IP Phones that are

working on a previous release of firmware may stop working if they are not correctly
wired.

But realize that a mis-cabled phone may still work, even with the new firmware, if the
network infrastructure supports Auto MDIX. If the network infrastructure supports Auto
MDIX, network loop can still occur if the network is not running the Spanning Tree Protocol
(STP) or a similar loop avoidance protocol.

As a preventative measure to reduce the potential for network degradation, and to prevent
mis-cabled phones from ceasing to work when their firmware is upgraded, please consider
taking the necessary steps to ensure your Nortel IP phones network cables are plugged into
the correct ports on the back of the phone – network cable into the network Ethernet port,
and the PC Ethernet cable (if connecting a PC) to the PC Ethernet port (little computer icon)
on the back of the phone.

Correction to VLAN Access Process (Applies to IP Phone 2007, 1120E, 1140E) –

may impact current network configurations

The 0621C4P, 0624C4I and 0625C4I firmware releases continue to support the changes to
the VLAN Access Process that were first introduced in 0621C2B, 0624C1E or 0625C1E
firmware.

When upgrading to 0621C4P, 0624C4I or 0625C4I from any load previous to 0621C2B,
0624C1E or 0625C1E respectively, the corrections to the VLAN access process, might
impact current customer network configurations, especially if something special was done to
compensate for the former operation of the phone.

1) Voice VLAN enabled with the Automatic VLAN Discovery feature – initial DHCP request is
forwarded based on the Data VLAN policy (i.e. untagged if Data VLAN is disabled or tagged
with the Data VLAN ID if Data VLAN is enabled). Subsequent DHCP requests and the
resolution of a Voice VLAN will be as per existing automatic operation.

The potential impact of this change to an installed customer network is:

 If they have a Data VLAN configured
 they have the auto configure VLAN feature enabled, and
 they DO NOT have their DHCP server on the Data VLAN

then the phone running these new firmware images will not register to the call server.
Customers should check that the DHCP server is on the Data VLAN if they've configured a
Data VLAN on their phones.
