Avaya 555-233-128 사용자 설명서

An H.323 IP telephone can be either in use with possible customized settings or out of the box 
with factory default settings. An out of the box telephone requires accessing the manual 
programming mode early in the process and setting the Signaling Protocol Identifier (SIG) 
parameter to “SIP.” Converting to SIP early avoids having to first load H.323 software, log in, 
and then invoke the “in use” process to load the SIP software. 

Note:

For information about the SIG parameter, see “Choosing the Right Application 
File and Upgrade Script File” in the 4600 Series IP Telephone LAN Administrator 
Guide (Document Number 555-233-507). For information on setting or changing 
the SIG parameter, see
