A method and apparatus for voice path assurance (VPA) testing in a packet
network such as an Internet Protocol (IP) network is provided. More
specifically, the invention relates to a voice path assurance (VPA)
testing technique that is initiated by the terminating side of a logical
connection through an IP network. The technique of the present invention
is used to verify connectivity and performance--during a call set-up
procedure--between the terminating endpoint and the originating endpoint
of the logical connection through the IP network.
