H.323 Call Setup from H.323 Network to Circuit Switched Network

Figure D-3 illustrates a CiscoATA initiating a connection to a Circuit Switched Network (CSN) or

Public Switched Telephone Network (PSTN) Gateway router through its local H.323 gatekeeper.

Note This scenario assumes that the H.323 configuration employs Fast Start Si gnaling with tunneling

capability.
