TFTP Configuring
You can configure many parameters on the Cisco IP Phone models
7902G/7905G/7912G using a profile file stored on the TFTP server. A profile file
is a binary file that contains a list of tag, length, and value triplets (TLVs) that
represent some of the configuration parameters for the Cisco IP Phone. You can
edit a text version of a profile file and then convert it to a binary file for the phone
to download.
TFTP configuring works as follows:
1. The Cisco IP Phone 7902G will try to download from the TFTP server the
profile file ffxxxxxxxxxxxx. The Cisco IP Phone model 7905G will try to
download from the TFTP server the profile file ldxxxxxxxxxxxx. The
Cisco IP Phone model 7912G will try to download from the TFTP server the
profile file gkxxxxxxxxxxxx. In these file names, each xx is the two-digit
lowercase hexadecimal representation of each integer in the phone’s MAC
address.
2. If the ffxxxxxxxxxxxx, ldxxxxxxxxxxxx, or gkxxxxxxxxxxxx profile file does not
exist, the Cisco IP Phone 7902G will try to download the profile file
ffdefault.cfg, the Cisco IP Phone 7905G will try to download profile file
lddefault.cfg, and the Cisco IP Phone 7912G will try to download profile file
gkdefault.cfg
The ffxxxxxxxxxxxx, ldxxxxxxxxxxxx, or gkxxxxxxxxxxxx profile file can be used to
configure a particular Cisco IP Phone. The ffdefault.cfg, lddefault.cfg, or
gkdefault.cfg profile file can be used to simultaneously configure multiple phones
of the same model with the same information.
