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

Step 5: Deskphone and SIP Proxy Server

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.

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
