Chapter 2 Getting Started with Your Cisco SIP IP Phone
Installing the Cisco SIP IP Phone
If the Cisco SIP IP phone is using DHCP to obtain the IP settings, the phone queries the DHCP
server. If the phone is not using DHCP, then the phone uses IP settings that are stored in Flash
memory.
4.
The TFTP server is contacted.
The TFTP server contains the latest Cisco SIP IP phone firmware image and the dual boot file
(OS79XX.TXT) that enables the phone to automatically determine and initialize for the VoIP
environment in which it is being installed.
If the phone is using the TFTP server to obtain its SIP parameters, there should also be a
configuration file or files on the TFTP server that the phone will request and download. In the
configuration file or files, SIP parameters that are required by the phone to operate in a SIP VoIP
environment are defined. If the phone is not obtaining its SIP parameters via the TFTP server, the
phone uses SIP settings that are stored in Flash memory.
5.
The firmware version is verified.
If the phone is obtaining its SIP parameters via a TFTP server, the configuration files are requested.
If the phone determines that the image defined in a configuration file differs from the image it has
stored in Flash memory, it performs a firmware upgrade.
When performing a firmware upgrade, the phone downloads the firmware image from the TFTP
server, programs the image into Flash memory, and reboots.
