Malek, your comment: " We have a UC320W phone system connected to a SF300-24P router as an extension.  Both my phones an my PC are connected to the router with the subnet of 255.255.255.0 which is standard.  The phones are purchased brand new and they do not have device administrator password.  One of the phone IP address is 10.1.1.11 which is located in the Voice VLan of both UC320W and Router.  I am able to configure some of the phones configuration from the UC320W admin panel like buttons and address book but there is not phone's firmware upgrade section there. - which make sense -" The UC320W controls the firmware and configuration of each phone provisioned on the unit.  It locks down the phone so that is why you do not see option to update the firmware. When you change firmware on the UC320W it will automatically update the firmware on the phones if needed. There is a community specifically on UC320W questions and issues. Thanks Randy ... View more

Malek, However I am cannot find  the "Firmware Upgrade tab" in the phone web interface. Can you go to any tabs and make any changes?  I believe your phone is read only thus you cant access the "Firmware Upgrade tab". Also make sure you are in admin mode and not user mode.  You must have admin rights to make changes. Randy ... View more

The UC320W should detect the SPA525G2 phone via CDP and assign an IP address via the voice VLAN (as your SPA504 and SPA508 phones do). Try factory default SPA525G2 phone and retry. You can also try to disable CDP on the SPA525G2 phone and save the configuration.  One last item is SPA525G2 could be a -RC sku and are for Service Provider deployments but the units should still obatain an IP address upon bootup.

Hi, If the SPA525G2 phones are connected to UC320W the phone firmware is bundled into the UC320W firmware. The UC320W will load the supported firmware load and features for the SPA525G2 phones. Once the UC320W detects the SPA525G2 phone it will automatically install the firmware version that is supported by UC320W. One additional point, opening a web broswer to the SPA525G2 IP address, the firmware upgrade option will not be displayed (locked out) when connected to UC320W. The phone firmware configuration utility is for SPA30X and SPA50X phone models and is included in the phone firmware zip file on Cisco.com Randy ... View more
