VoIP Configuration Examples Chapter 4 Configuring Voice over IP Note PBXs should be configured to pass all dual tone multifrequency (DTMF) signals to the Cisco IAD. We recommend that you do not configure "store-and-forward" tone. Note If you change the gain or the telephony port, make sure that the telephony port still accepts DTMF signals. PSTN Gateway Access Using an FXO Connection The following example shows how to configure VoIP to link users with the PSTN gateway using a Foreign Exchange Office (FXO) connection. In this example, users connected to Router SJ in San Jose, California, can reach PSTN users in Salt Lake City, Utah, using Router SLC. Router SLC in Salt Lake City is connected directly to the PSTN through an FXO interface. Figure 4-3 shows the topology of this connection example. Figure 4-3 PSTN Gateway Access Using FXO Connection Example FaE 0/0 FaE 0/0 IAD SJ Analog to FXS IAD IP cloud IAD SLC IAD FXO 1(408) 555-4000 172.16.1.123 San Jose Voice port 2/0 172.16.65.182 Voice port 2/0 PSTN user PSTN cloud Salt Lake City 95109 Note This example assumes that the company already has established a working IP connection between its two remote offices.
