Introduction

Nortel* is pleased to announce the general availability of a maintenance release of UNIStim
firmware version 0604DAS for the Phase II IP Phone 2001, Phase II IP Phone 2002, and
Phase II IP Phone 2004. Nortel is also pleased to announce the general availability of a
maintenance release of UNIStim firmware version 0621C3J for the IP Phone 2007. In
addition, Nortel is pleased to announce the general availability of maintenance releases of
UNIStim firmware version 0624C3C, 0625C3C and 0627C3C for the IP Phone 1120E, IP
Phone 1140E and IP Phone 1150E respectively.

Nortel recommends an upgrade to these maintenance releases of firmware for all applicable
IP Phones and Call Servers at the earliest convenience. These maintenance releases are
being provided as a no charge update to all customers.

These maintenance releases deliver general quality improvements.

Quality Improvements

The 0604DAS, 0621C3J, 0624C3C, 0625C3C and 0627C3C firmware loads bundle together
numerous resolved issues and closed cases into a maintenance release. In total, over 100
resolved issues have been closed, and over 40 customer cases have been closed in these
new firmware loads. The list of resolved critical issues and the list of closed cases since the
last suite of generally available (GA) firmware loads (0604DAD, 0621C3A, 0624C39,
0625C39 and 0627C39 respectively) are listed below.

Product Advisements

These firmware releases modify the operation of the phone slightly from some earlier
previous versions of firmware in a couple key areas:

Network Loop (Applies to IP Phone 2002, 2004, 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 0604D9H, 0621C2B, 0624C1E and 0625C1E. One
important note when upgrading to 0604DAS, 0621C3J, 0624C3C or 0625C3C from any load
previous to 0604D9H, 0621C2B, 0624C1E or 0625C1E respectively, is that IP Phones that
were inadvertently mis-wired 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 2002, 2004, 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. Phase II IP Phones (2002 and 2004)
running firmware previous to 0604D9H, 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 safe guard the network by
not allowing phones that are mis-cabled to function. This means that the IP Phones that

are working on a previous release of firmware will stop working if they are not
correctly wired. 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 2002, 2004, 2007, 1120E,
1140E) – may impact current network configurations

The 0604DAS, 0621C3J, 0624C3C and 0625C3C firmware releases continue to support the
changes to the VLAN Access Process that were first introduced in 0604D9H, 0621C2B,
0624C1E or 0625C1E firmware.

When upgrading to 0604DAS, 0621C3J, 0624C3C or 0625C3C from any load previous to
0604D9H, 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.

2) Stripping of egress Data VLAN tag is configurable – VLAN tag stripping can be enabled
or disabled in addition to enabling VLAN support on the phone’s PC port. If VLAN is enabled
on the phone’s PC port (ingress direction), the default will be to strip the tag on the egress
direction. However, this can be manually overridden to disable stripping even if VLAN
tagging (ingress direction) is enabled on the phone’s PC port. Likewise if VLAN is disabled
on the phone’s PC port, the default will be to NOT to strip the tag on the egress direction.
But this again can be overridden to enable stripping even if VLAN is disabled on the phone’s
PC port (ingress direction).

If stripping is disabled, the packet is sent to the phone’s PC port unmodified. If stripping is
enabled, the 802.1q header is removed (assuming one exists) from the packet before
forwarding it out the phone’s PC port

Important Note: While these changes corrects the VLAN access process, the change
might impact current customer network configurations, especially if something special was
done to handle the prior operation of the phone.

Description, Installation and Operation Document, NTP 553-3001-368.

on the phone, and

One way speech path behind NAT Routers (Applies to IP Phone 2001, 2002, 2004,
2007, 1120E, 1140E, 1150E)

A problem exists that with some NAT routers that causes one way speech path. This
problem is addressed by the application of patch MPLR21030 on the Communication Server
1000 Release 4.5 and 4.0. (Note: IP Phone usage behind NAT routers is not supported with
Communication Server 1000 Release 3.0). The Communication Server 1000 patch is
located in the Meridian PEP library at the www.nortel.com/support

web site.
