Provided is a method, computer program product, and apparatus for estimating the quality of a call in which a first user terminal will comprise an end point. The method comprises establishing an end-to-end connection between a first user terminal and a node, which end-to-end connection is via an access point of a network by which the first user terminal is connected to the network; displaying information indicative of an expected quality of a call in which the first user terminal will comprise an end point, in dependence on information indicative of the quality of the end-to-end connection; and providing call initiation means for enabling a user to then selectively establish a call between the first user terminal and a callee. Also provided is a method, computer program product, and apparatus for estimating the quality of a call between a first user terminal and a potential callee.
