5. Press CONFIRM. The downloading process begins and the phone reboots. This 

process may take approximately 1 to 2 minutes. When the time and date appear on 
the display, the download and reboot is complete and the phone is ready for use.  

To upgrade the firmware from the boot program: 

• Access 

the 

Configuring in the Main and Boot Programs topic in the Administrator’s 

Web Configuration Tool Online Help (see page 3). 

CAUTION: DO NOT remove power from the phone while firmware is downloading 
or the phone is rebooting. This may result in severe damage to your phone. 

Troubleshooting Tip: If your phone displays "SIP MAIN NOT FOUND", it is likely 

that your system has experienced a power failure. The SIP Phone Boot firmware 
"borrows" Flash sectors from the SIP Main area during firmware installation. At the end 
of a normal installation, the sectors are restored without affecting SIP Main. However, if 
power is removed during Boot installation, then SIP Main is erased and will have to be 
reinstalled on the phone. 

You can configure phones to poll the server for new versions of firmware. When the 
phone detects a firmware upgrade, it uploads the new version and stores it in memory. 
When it is next idle, the phone reboots with the new firmware. 

To automate firmware upgrades, your Administrator must set the Firmware Upgrade 
option and a polling interval on the Firmware Update page of the Web Configuration 
Tool. For programming options, refer to the online help supplied with the Web 
Configuration Tool. 

To upgrade firmware on multiple phones, refer to the Mass Deployment topic in the 
Administrator Tools section of the Web Configuration Tool Online Help. 

SIP Enhanced mode enables your 5235 phone to support server-enhanced shared lines 
including Sylantro Bridged Line Appearance (BLA) and Broadsoft Shared Call 
Appearance (SCA). 

Note: After you enable SIP Enhanced mode on a phone, it becomes a dedicated SIP 
phone. You can not toggle back to MiNET mode. 

To enable SIP Enhanced mode: 

1.  From the Web Configuration Tool home page, click Advanced Features. 

2.  In the SIP Enhanced Mode list, select On.  

3. Click 

Save and Reboot. 

To enable SIP Enhanced mode in the Boot program, refer to the Configuring Network 
Settings section of the Web Configuration Tool online help.
