    48 * It provides services for creating, using and terminating SIP REFER

    49 * dialog associations. User can have multiple REFER dialog associations

    50 * per same SIP dialog.

    51 * Implementation handles SUBSCRIBE on the dialog level defined by Call-Id,

    52 * local and remote tags;

    53 * User is responsible for "Refer-to" header semantics.
