//:The PtAddressForwarding class represents a forwarding instruction.
// This instruction indicates how the phone system should forward
// incoming telephone calls to a specific address. The attributes
// of a forwarding instruction are:
// <p>
// <ul><li>
// The forwarding instruction's <b>type</b> tells the phone
// system when to forward the call. Currently, three types are
// supported: always forward incoming calls, forward incoming calls
// when the address is busy, and forward incoming calls when no
// one answers.</li>
// <br>
// <li>
// The forwarding instruction's <b>filter</b> identifies the set
// of incoming calls to which it applies. A forwarding instruction
// can apply to all calls, to external calls only, to internal calls
// only, or to calls from a specific calling address. </li>
// </ul>
