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.

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.
Outstanding Known Issues
Although the 0604DBG, 0621C4J, 0623C4D, 0624C4D, 0625C4D and 0627C4D firmware
releases greatly improve the overall quality of the IP Phones, these firmware releases still
include some outstanding known issues:
Backlight Interaction with USB devices (IP Phone 2007, 1120E, 1140E and 1150E)
Some USB devices (i.e. Mice or Keyboards) send regular coordinate update messages to
the phone even when the device is not being used. This can cause the sleep mode for the
backlight to not be properly invoked.
Contrast Adjustments: Local & TPS contrast adjustments are not synchronized (IP
Phone 1110, 1120E, 1140E and 1150E)
The IP Phone 1110, 1120E, 1140E and 1150E graphical display contrast control can be
adjusted either locally (on the phone) or through the call server (TPS) control. The
Communication Server 1000 TPS does not yet synchronize its contrast setting with the local
control. This means if the local control is used exclusively, then whenever the phone has a
power cycle, the TPS contrast setting is restored and the user may need to adjust contrast
again.
The local contrast control on the IP Phone 1110, 1120E, 1140E and 1150E is accessed by a
“double press”
of the Services key and selecting “1. Preferences”, then “1. Display Settings”
in the menu. The TPS contrast control is accessed with a “single press
” of the Services key,
then selecting “Telephone Options”, then “Contrast Adjustment”.
