Profile Formats
This section demonstrates the generation of configuration profiles. To explain the
functionality in this section, TFTP from a local PC is used as the resync method,
although HTTP or HTTPS can be used for testing as well, if it is convenient. This

Profile Compression
A configuration profile in XML format can become quite large if all parameters are
individually specified by the profile. To reduce the load on the provisioning server,
the IP Telephony Device supports compression of the XML file, using the deflate
compression format used by the gzip utility (RFC 1951).
Exercise
STEP 1
Install gzip on the local PC.
STEP 2
Compress the basic.txt profile from earlier exercises, by invoking gzip from the
command line:
gzip basic.txt
This generates the deflated file basic.txt.gz.
STEP 3
Save the deflated file in the TFTP server virtual root directory.
STEP 4
Modify the Profile_Rule on the test device to resync to the deflated file in place of
the original XML file, as in the following example:

STEP 6
Observe the syslog trace from the IP Telephony Device.
