The menus shown by phones when first connected to the system depend on the particular model of phone. This section can only provide a general summary.
For most Avaya SIP phones, the general process is as follows:
Using DHCP, the phone requests IP address information from a DHCP server. That includes using its DHCP SSON setting to request file server address information from the matching DHCP server option.
Using the file server address provided, the phone requests an upgrade text file appropriate for its particular model from the file server.
If the IP Office is the file server, it auto-generates an appropriate file unless one has been uploaded to its file storage.
Using the upgrade file, it compares the details of the firmware it is already running and that which the firmware the file says it should be running in order to work with the IP Office system.
If necessary the phone requests the new firmware files from the file server.
Typically as part of loading any new firmware the phone reboots and restarts the process.
The phone now requests the settings text file appropriate for its particular model from the file server. This file contains a wide range of phone settings including details of the SIP server and protocols it should use and the certificate name if using TLS.
If the IP Office is the file server, it auto-generates an appropriate file and adjust various settings in that auto-generated file to match settings in the IP Office system configuration.
The phone requests any further files indicated in the settings file, for example language files and security certificates.
If the phone has previously been connected, it attempts to re-register with the system using the previous account settings.
If the phone is new or its registration is rejected, it will display menu options for registering with the system. When prompted for a username or similar, enter the IP Office user's Extension number.
When prompted for a password or similar, enter the Phone Password set for the extension entry in the configuration. .
