5. Download the master configuration file.
This file is either called <MAC-address>.cfg or 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.
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.
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 will also download all
the configuration files that are listed in the master configuration file.
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
1.4 support this feature. Refer to the latest Release Notes to verify if the image is
signed.
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.
