Administering DIFFSERV

The DiffServ values change to the values administered on the call server as soon as the phone
registers. For more information on DiffServ values, see chapter on Network Quality Administration in
Administration for Network Connectivity for Avaya Communication Manager, 555-233-504. Unless
there is a specific need in your enterprise LAN, do not change the default values.

Administering NAT

Network Address Translation (NAT) usage can lead to problems that affect the consistency of
addressing throughout your network. All H.323 IP deskphones support NAT interworking. Support
for NAT does not imply support for Network Address Port Translation (NAPT). The phones do not
support communication to the PBX through any NAPT device.
NAT requires specific administration on the call server. A direct Avaya IP phone-to-Avaya IP phone
call with NAT requires Avaya Communication Manager Release 3.0 or later software. For more
information, see Administration for Network Connectivity for Avaya Communication Manager,
555-233-504 on the

Administering Voice mail

Voice mail for deskphones with Communication Manager 4.0+

Release 1.2 and later provides native support for 9600 Series IP deskphones running on
Communication Manager Release 4.0 or later. Although the 9608, 9611, 9621, and 9641 are not
natively supported in Communication Manager 4.0, those phones are natively supported as of
Communication Manager 6.2. See
When native support applies, when you press the Messages button, the deskphone first determines
if the call server has a dedicated number for retrieving voice mail. If a dedicated number exists, the
deskphone proceeds with voice mail retrieval.
