Videoconference Using 
SIP
This chapter describes how to conduct a videoconference 
using SIP (Session Initiation Protocol). SIP is a protocol to 
start communication via a network standardized by IETP 
(Internet Engineering Task Force).
For conducting a videoconference with an IP phone using 
SIP, installation of the optional PCSA-SP1 SIP software in 
this system and connection via a SIP server are required.
Restrictions on the use of the SIP software
• The settings in the Setup menu are disabled during an 
SIP connection.
• An SIP connection cannot be established when 
“Encryption via LAN” is set to “On” and “Standard” is 
selected as the signal encryption method.
