The routing that you administer with Precedence Routing uses the same capacity tables as the ARS feature. These tables include patterns and analysis tables. You can view the real-time capacity usage with the change precedence-routing analysis command. The Percent Full field displays how much of the available capacity is used for routing information.

H.323 IP trunks do not support data calls that use any type of modem or data module. Do not administer H.323 IP trunks for users who make data calls over trunk facilities. H.323 IP trunks can be used for voice calls.
