## 9600 Series IP Telephones vs. 4600 Series IP Telephones

### What’s New?

- Configuration files and firmware files are downloaded via HTTP only.
- A new 96xxupgrade.txt configuration file is provided with each 9600 Series IP Telephone software distribution, but a 46xxsettings.txt configuration file continues to be used for customer settings. You maintain settings for both 9600 and 4600 Series IP Telephones on this single settings file.
- Backup and restore of user data is accomplished using HTTP only. Digest authentication is supported for improved security.

Important: HTTP Backup/Restore requires Apache R2.0.55 or greater or IIIS 5.5 or greater.

- DHCP uses site-specific option number (SSON) 242 as a default instead of option 176.

NOTE: The IETF is reclassifying option numbers 128-223 for standard use. For more information, see RFC 3942.

- After a configured period of inactivity, the display backlight turns off to conserve power. The default period is two hours.
- After a configured period of inactivity, the telephone displays a screen saver. The default period is four hours. The screen saver is currently not customizable.
- A new HIS cord must be used to connect a headset to a 96xx telephone.
- A new document, Avaya one-X Deskphone Edition File Server Application Reference Guide, supports HTTP download and user data backup/restore using an Avaya File Server application.
