SIP Mode
Note: The default password for an 
administrator is 456.
After you connect your phone for SIP use, and your phone starts, you need to minimally 
configure your phone so it can operate properly. You can conveniently configure the phone using 
the Polycom Web Configuration Utility.
To set up the phone for SIP use:
1. Launch a web browser from a computer on the same network as your phone. 
2. In the address bar of your web browser, enter the IP address of your phone, and then press 
the Enter key. To find your phone’s IP address, press          on your phone, and then select 
Status > Platform > Phone. From the Phone screen, scroll to the IP address.
3. From the Web Configuration Utility login screen, select Admin, and then enter the 
administrator’s password.
4. From the Main Menu, select Simple Setup to display the minimum set of options you 
need to configure, as shown next. Enter the relevant information for your phone, and 
then click Save.
Your phone will now be registered, and you can place and receive calls. You will
know your phone is registered if the Registered icon,       , displays on the idle
screen, as shown next.
To configure more advanced settings, see the Administrator’s Guide for the Polycom 
UC Software available from the 
SoundStation Duo Support web page.
