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
telephones do not support communication to the PBX through any NAPT device.
NAT requires specific administration on the call server. A direct Avaya IP Telephone-to-Avaya
IP Telephone call with NAT requires Avaya Communication Manager Release 3.0 or greater
software. For more information, see Administration for Network Connectivity for Avaya
Communication Manager (Document Number 555-233-504) on the Avaya support Web site.

9600 Series IP Deskphones with CM 4.0+ Native Support

Release 1.2 provides native support for 9600 Series IP Deskphones running on Avaya
Communication Manager (CM) Release 4.0 or later. When native support applies, pressing the
Messages button causes the telephone to first determine if the call server has a dedicated
number for retrieving voice mail and when found, to proceed with voice mail retrieval.

9600 Series IP Telephones Aliased as 4600 Series IP Telephones

When native support does not apply, 9600 Series IP Deskphones are aliased as 4600 Series IP
Telephones and run under CM Release 3.1 or later. In this case, use the settings file to
configure the Messages button by setting the system parameter
string. MSGNUM examples are:
a standard telephone number the telephone should dial to access your voice mail system,
●
such as AUDIX or Octel.
a Feature Access Code (FAC) that allows users to transfer an active call directly to voice
●
mail. FACs are supported only for QSIG-integrated voice mail systems like AUDIX or
Octel. QSIG is an enhanced signaling system that allows the voice mail system and Avaya
Communication Manager Automated Call Processing (ACP) to exchange information.
When the user presses the Messages button on the telephone, that number or FAC is
automatically dialed, giving the user one-touch access to voice mail.
