Before You Upgrade
When you upgrade a Cisco SPA50X or Cisco SPA30X IP Phone, if you have installed a firmware version prior to 7.5.2b, you must first upgrade to 7.5.2b before you upgrade to release 7.5.3 or to a later release. See the following table for more information.

Firmware release 7.6.2 includes all customer-found defects that have been fixed after firmware release 7.6.1. For SPA5x5, the openssl upgrades to openssl-0.9.8zh.

Note These parameters apply only to the Cisco Small Business SPA51X IP Phone.

User Web Password
The new User Web Password parameter eliminates the user requirement for daily password entry on the LCD GUI to use the basic functions. The basic functions include CFwd, Directory, Redial, and Corporate Directory.
The options are No and Yes:
If the User Password field is not empty, using this field restricts user access through the web interface and LCD GUI.
If the User Password field is empty, no password is needed to access the LCD GUI. However, the user must enter a password to access the web interface. This is the User Web Password parameter that was set earlier.

Behavior During Times of Network Congestion
Anything that degrades network performance can affect voice and video quality, and in some cases, can cause a call to drop. Sources of network degradation can include, but are not limited to, the following activities:
Administrative tasks, such as an internal port scan or security scan
Attacks that occur on your network, such as a Denial of Service attack
To reduce or eliminate any adverse effects to the devices, schedule administrative network tasks during a time when the devices are not being used or exclude the devices from testing.
