Pstn Gateway Access Using An Fxo Connection; Iad Sj Configuration - Cisco 2431 - IAD Router Software Configuration Manual

VoIP Configuration Examples
PBXs should be configured to pass all dual tone multifrequency (DTMF) signals to the Cisco IAD. We
Note
recommend that you do not configure "store-and-forward" tone.
If you change the gain or the telephony port, make sure that the telephony port still accepts DTMF
Note
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.
