This section describes the process for 96x1 Series Phone SIP firmware download using the
B5800 Branch Gateway. The procedure required to replace the H.323 version of the firmware
to the SIP version is not covered here.
B5800 Branch Gateway support for SIP phone firmware download
This capability is made available in the B5800 Branch Gateway Release 6.1 SP2. Note that a
hidden B5800 system configuration parameter (the B5800 NoUser Source Number
‘ENABLE_SIP_FIRMWARE_DOWNLOAD’) needs to be configured.
Enabling the DHCP server on the B5800 Branch Gateway
About this task
Before upgrading the phones, a DHCP server has to be set up to provide the correct HTTP
server address to the phones. The preferred approach is for the DHCP server to be enabled
on each B5800 Branch Gateway. Perform this procedure on each B5800 Branch Gateway.
Procedure
1. Start Manager and connect to the B5800 Branch Gateway.
2. In the left navigation pane, click System.
3. Click the LAN tab.
4. In the LAN Settings tab, under DHCP Mode, click Server.
5. Click the Advanced button.
6. Click the Apply to Avaya IP Phones only check box to select this option.
About using external DHCP servers
As an alternative to enabling the DHCP server on each B5800 Branch Gateway, external DHCP
servers can be used if preferred. In this case, the DHCP server must be configured to provide
the IP address of each B5800 Branch Gateway as the HTTP server address in the Site-Specific
Option of the DHCP response to the phone.
The SIP phone configuration file 46xxsettings.txt has to be edited and then loaded to the B5800
Branch Gateway. This should be done as part of installation and does not have to be repeated
when upgrading to a new phone SIP firmware.
