Application—Single-phone PSTN and VoIP access
The SmartNode 4520 Series with a combination of FXS and FXO ports can be used to make and receive calls via PSTN and Internet calling services over the same telephone handset (see figure 15). Using individually con- figurable routing tables, an outbound call can be directed to the local PSTN connection or to an Internet tele- phony service provider (ISTP). Inbound calls from the Internet and the PSTN can ring the same phone.
