Administrator’s Guide SoundPoint IP / SoundStation IP

5.Download the master configuration file.

This file is either called <MAC-address>.cfgor 000000000000.cfg . This file is used by the both the bootROM and the application for a list of other files that are needed for the operation of the phone.

6.Examine the master configuration file for the name of the application file, and then look for this file on the boot server.

If the copy on the boot server is different than the one stored in flash memory or, if there is no file stored in flash memory, the application file is downloaded.

Note	If the Application is any SIP version prior to 1.5, the bootROM will also download all
	the configuration files that are listed in the master configuration file.

7.Extract the application from flash memory.

8.Install the application into RAM, then upload a log file with events from the boot cycle.

The bootROM will then terminate, and the application takes over.

Application

The application manages the VoIP stack, the digital signal processor (DSP), the user interface, and the network interaction. The application managed everything to do with the phone’s operation.

The application is a single file binary image and, as of SIP 1.5, contains a digital signature to prevent tampering or loading or rogue software images.

Warning If your phones are using bootROM 3.0 or later, the application must be signed. All SIP 1.5 applications and later are signed, but later patched versions of 1.3 and

1.4support this feature. Refer to the latest Release Notes to verify if the image is signed.

There is a new image file in each release of software.

The application performs the following tasks in order:

1.Downloads system and per-phone configuration files and resource files.

These files are called sip.cfg and phone1.cfg by default. You can customized the filenames.

Note	If the Application is any SIP version prior to 1.5, the bootROM would have
	downloaded all the configuration files that are listed in the master configuration file.
