ABSTRACT:
Methods and apparatus for assessing propagation delay based on factors in addition to the propagation delay associated with a selected circuit, in order to provide a more accurate propagation delay value associated with a communication transaction. Factors to be assessed include the propagation delays associated with a particular bearer service involved in the communication transaction, a type of information being transmitted, any supplementary peripheral equipment involved with the communication transaction, any transmission media involved with the call, and/or any combination of these factors in a communication transaction.
