Application—Convert Legacy PBX to VoIP
The SmartNode 4970A Series can be used to make and receive calls to and from the public ISDN network and
Internet Telephony services on any ISDN Terminal (Phone or PBX) (see
figure 4 ). Using individually configu-
rable 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.

to bring SIP-trunking service to a traditional PBX. .
