Remember that variables in this case are "channel variables" and are almost
always associated with a specific phone call. These variables for a user are
set whenever that user makes a phone call.

Parameters a generally used for configuration purposes. The "dial-string"
parameter is related to the user channel, so when you do something like:
originate user/1001 &park()

It will use the dial-string parameter to turn "user/1001" into a proper
dialstring. If it makes your brain hurt then don't worry about it. :)

Parameters are used in lots of configurations. The most obvious examples are
in the SIP profiles and gateways. Are you working on something specific
where the differences between params and variables are causing you trouble?
