- location - gives the URL (or a signalling-protocol-dependent URL
pattern) of location or locations to be removed from the set. If this
parameter is not given, all locations, subject to the constraints of
the other parameters, are removed from the set.
- param - caller preferences parameters to apply.
- value - value of caller preference parameters.
If param and value are present, their values are comma-separated lists of
caller preferences parameters and corresponding values, respectively. The
nth entry in the param list matches the nth entry in the value list. There
MUST be the same number of parameters as values specified. The meaning of
these parameters is signalling- protocol dependent. |
