Systems and methods are provided for facilitating communication sessions between endpoints over one or more networks. In one implementation, a method includes receiving, by at least one processor, first data indicating that a communication session has been initiated to at least one endpoint. The method also includes receiving, by the at least one processor, second data corresponding to one or more application level metrics associated with the communication session and determining, by the at least one processor, during the communication session, based on the second data, a packet duplication model for transmitting one or more data packets over one or more networks.
