Abstract
A method includes receiving at an ingress session exchange device a call admission control (CAC) condition and a CAC value associated with an endpoint of a first egress session exchange device and CAC-related information associated with an endpoint of a second egress session exchange device. The ingress session exchange device is at a border of a session over internet protocol network. A first call admission calculation is performed at the ingress session exchange device to determine whether the CAC condition is satisfied. A second call admission calculation is performed at the ingress session exchange device when the CAC condition is unsatisfied. The first call admission calculation and second call admission calculation are based on the CAC-related information.
