In an apparatus and method for testing a VoIP network (1), a special mode sequence and a telephone number are transmitted on the VoIP network (1). In response to the transmission of the special mode sequence and the telephone number, a network connection is established on the VoIP network (1). Test data is transmitted from a first endpoint (10, 14, 18, 20, 22) of the network connection to a second endpoint (10, 14, 18, 20, 22) of the network connection. In response to the transmission of the test data, either the same or similar test data is returned to the first endpoint (10, 14, 18, 20, 22). The transmitted and returned test data are processed to determine at least one of: an amount of network delay in the transmitted and returned test data, an amount of jitter in the rate of the returned test data, and an amount of lost test data between the transmitted test data and the returned test data.
