Avaya 1603 Guia Do Utilizador

Note:

All local administrative procedures are on a phone-by-phone basis. 
Administration using Communication Manager, DHCP, and HTTP applies to the 
telephone system itself or to a range of telephones. 

Network Address Translation (NAT) usage can lead to problems that affect the consistency of 
addressing throughout your network. All H.323 IP Telephones 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 media 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.

The DiffServ values change to the values administered on the media server as soon as the 
telephone registers. For more information, see Chapter 4 “Network Quality Administration” in 
Administration for Network Connectivity for Avaya Communication Manager (Document 
Number 555-233-504). Unless there is a specific need in your enterprise LAN, Avaya 
recommends that you do not change the default values.

You can set the system parameter 

 to any dialable string. An example is the 

telephone number users would dial to access your voice mail system such as AUDIX or Octel. 
For more information, see 

. When the user presses the Message button on the 

telephone, that number is automatically dialed, giving the user one-touch access to voice mail.
