Abstract
The quality of service existing in a data packet network during the course of communication of a voice call through a data network, such as the Internet, is monitored. A minimum acceptable level of service may be predefined with a threshold quality level stored in the user's Call Processing Record (CPR) in the AIN Integrated Services Control Point (ISCP). If the monitored quality is maintained in excess of the stored threshold, communication of the call continues through the established course of transmission. If the measured quality of service on the data network is not satisfactory, the routing of the call is changed to communication solely through a voice telephone network connection, which may include an Interexchange Carrier link, without terminating the call. The packet data network is thereby bypassed to obtain voice grade quality while maintaining the call.
