Methods and a system for connecting a call across a network of network elements as a path for the call is being set up are provided. The call comprises a parameter for which a value must be assigned for each segment of the path between adjacent network elements. At least one network element supports multiple values for the parameter. A network element on the communication path receives an indicator that indicates that network elements along the path of the call are required to use a predetermined value for the parameter. A connection is established to an adjacent network element on the path using the predetermined value for the parameter, prior to setting up a next segment of the path.
