摘要： The present invention provides a system and method for establishing the availability of a node to received a voice over internet protocol (VoIP) call. The present invention comprises attempting to establish a VoIP call to a given node that is the target of the VoIP call, determining whether the attempt to establish the VoIP call is successful; and generating an alarm in response to a call failure. Acording to embodiments of the invention, the method may comprise extracting call metrics from a VoIP call that provide information regarding the quality of a VoIP connection and generating an alarm in response to the call metrics falling below a threshold.
