By default, don't attempt to do any CallerID handling at all with SLA because
it is known to not work properly in some situations.  However, add an option to
enable it for those that would like to use it anyway.

The short story behind this is that to properly handle CallerID with SLA, we
need the ability to change the CallerID on an existing call, and we are not
ready to handle that.
