    • In a remote management messenger system (RMMS), a method for screening a packet-based call originated from a caller via a caller telecommunication device (CTD) to a receiver telecommunication device (RTD) via the RMMS. The method includes activating, if a receiver associated with the RTD does not respond to the packet-based call within a predetermined time period, an answering-and-recording function (ARF) associated with the RMMS to enable the ARF to receive and record packets pertaining to the packet-based call while permitting the receiver to continue to hear the caller. The method also includes, if the receiver responds to the packet-based call after the ARF is activated, permitting the receiver to continue the packet-based call with the caller.
    • 在远程管理信使系统(RMMS)中,一种通过呼叫者电信设备(CTD)从经由RMMS向接收机电信设备(RTD)发起呼叫者的基于分组的呼叫的方法。 该方法包括如果与RTD相关联的接收机在预定时间段内对基于分组的呼叫没有响应,则激活与RMMS相关联的应答和录制功能(ARF),以使ARF能够接收和记录分组 属于基于分组的呼叫,同时允许接收机继续听到呼叫者。 该方法还包括,如果在ARF被激活之后接收机响应基于分组的呼叫,允许接收机继续与主叫方进行基于分组的呼叫。
