SmartNode 4630 User Manual	2 • Applications overview

How it works:

1.Connect the SmartNode to the PSTN and legacy PBX, and configure the call router to pass all calls from the PBX to the PSTN and vice versa. This first step will not affect any uses in the enterprise

2.Choose your ITSPs, and configure as many on the SmartNode as you need. Use the intelligent call router in the SmartNode to decide which call is forwarded to which ITSP, and which calls should go to the PSTN. This may be based upon least-cost routing criteria, or for example, on calling party number. The latter is ideal if you want to test calls to an ITSP before enabling it for all users within the enterprise.

3.Voice over IP can be switched off instantly on one single box (the SmartNode) to revert the system back to as it was before.

4.Build up an IP PBX system that uses the SmartNode as PSTN gateway. For all calls from this IP PBX, you can direct them to the PSTN or to ITSPs. Numbering plan adaptations are handled through regular expression matching by the SmartNode. No need to change anything on the PBXs.

5.Once the IP PBX is ready, you can choose on incoming calls from the PSTN, for each extension whether this extension is to be directed to the IP PBX or on the legacy PBX.

Application—Multi-service ISDN Internet telephony IAD

The SmartNode 4630 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 5). Using individually config- urable 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.
