Configuration File Examples
SoundPoint IP phones can be deployed in two basic methods. In the first 
method, Microsoft Live Communications Server 2005 serves as the call server 
and the phones have a single registration. In the second method, the phone has 
a primary registration to call server—that is not Microsoft Live 
Communications Server (LCS)—and a secondary registration to LCS for 
presence purposes.

as the call server:
