Abstract

In an arrangement where a switching system receives parameter(s) concerning the traffic expected on a call from a first user to a second user, the system determines a priority for the call based on the expected traffic parameter(s), and information is transmitted to the second user during the call based on the determined priority and with less than a maximum jitter. The priority is selected from a predefined priority table based on expected traffic parameters. The priority table is usable for both constant bit rate and statistical calls.
