Avaya 1603SW Betriebsanweisung

has the proper file, the deskphone proceeds as described in the next paragraph without 
downloading the binary file again.

The deskphone checks and loads the binary file, then uses the 16xxupgrade.txt file to look for a 
settings file, if appropriate. The optional settings file can contain settings you have administered 
for any or all of the 1603SW-I SIP IP Deskphones in your network. For more information about 
this download process and settings file, see 

.

In this step, the deskphone might prompt the user for an extension and password. The 
deskphone uses that information to exchange a series of messages with SM/SES, which in turn 
communicates with Avaya Communication Manager (CM). For a new installation and for full 
service, the user can enter the telephone extension and the SM/SES password. For a restart of 
an existing installation, this information is already stored on the deskphone. The deskphone and 
SM/SES, and SM/SES and CM exchange more messaging. The expected result is that the 
telephone is appropriately registered and call server data such as dial plan and feature button 
assignments are downloaded.

Edition SIP for 1603SW-I IP Deskphones Installation and Maintenance Guide.

Assuming proper administration, most of the problems reported by telephone users are likely to 
be LAN-based. Quality of Service, server administration, and other issues can impact user 
perception of IP deskphone performance. 

The Avaya one-X™ Deskphone Value Edition SIP for 1603SW-I IP Deskphones Installation and 
Maintenance Guide covers possible operational problems that might be encountered after 
successful installation. The User Guide also contains guidance for users having problems with 
specific IP deskphone applications.
