URL Resolution

The profile URL can contain a provisioning server name instead of an explicit IP
address. In this case, the IP Telephony Device performs a DNS lookup to resolve
the name.
A non-standard server port can be specified in the URL, using the standard syntax
:port following the server name.
Also, the configuration profile can be stored in a subdirectory of the server virtual
root directory. Again, this is specified using standard URL notation.
For example, the following is a valid Profile_Rule that requests the file spa962.cfg,
in the server subdirectory /cisco/config, for the TFTP server running on host
prov.telco.com, which listens for connection on port 6900.
tftp://prov.telco.com:6900/cisco/config/spa962.cfg
Again, macro expansion can be used anywhere in the URL. This can be convenient
in organizing a directory of profiles on the server for the deployed devices. For
example, a profile subdirectory name might be supplied for each IP Telephony
Device in a dedicated general purpose parameter, with its value referred within a
common profile rule via macro expansion.
For example, GPP_B has the following definition:
Dj6Lmp23Q
The Profile_Rule has this value:
tftp://prov.telco.com/cisco/$B/$MA.cfg
Then, when resyncing, this IP Telephony Device (assuming a MAC address of
000e08012345) requests the profile at the following URL:
tftp://prov.telco.com/cisco/Dj6Lmp23Q/000e08012345.cfg
