At an SBS Originating Node the parties involved in an SBS call can be determined via status commands, as shown in Parties Involved in an SBS Call.

At an SBS Terminating Node the parties involved in an SBS call can be determined in a similar fashion to that described for the SBS Originating Node by replacing the originating station/trunk with the terminating station/trunk, and replacing the outgoing bearer trunk with the incoming bearer trunk.

At an SBS Tandem Node executing status trunk on an SBS trunk member will show that the trunk is in-service/active. However, the Connected Ports and SBS Associated Port fields will be blank. This should not be misinterpreted as a hung trunk. The associated bearer call will most likely route entirely through the PSTN. Even if the associated SBS bearer call routes through the SBS Tandem Node, that node will have no way of associating the SBS signaling and SBS bearer calls. Association of the signaling and bearer calls can only be accomplished at the SBS Originating and SBS Terminating Nodes.
