ABSTRACT:
A method of selectively improving the quality of calls carried by a communications network. The method comprises defining off-peak and peak call periods, and during off-peak periods, for each call carried by the network, analysing call data to determine whether or not a network based Voice Quality Enhancement function should be applied to the call and, if yes, applying the function to the call. A database is maintained containing subscriber and/or terminal identities together with respective Voice Quality Enhancement function requirements, said requirements being updated based upon determinations made during said off-peak periods. During peak periods, said network based Voice Quality Enhancement function is invoked on a per call basis in dependence upon the requirements contained in said database for the user(s) and/or terminal(s) participating in the calls.
