Running Example
The following SIP --> PSTN call example is used as a running example in this guide to explain how a BorderNet
500 Gateway dial plan can work:
SIP Phone: sip:3000@10.10.11.191 dials 9541
The following table shows the translation of the telephony messages as they move through the SIParator and
Diva SIPcontrol/Diva Media Board:

A call flow and example of a PSTN --> SIP call are shown below.
Call Flow
The following picture shows the call flow from a PSTN interface to SIP:
In this picture:
• Point A is the incoming ISDN message from the PSTN device to the Diva Media Board.
• Point B is the internal interface between Diva SIPcontrol and the SIParator.
• Point C is the outgoing SIP INVITE message to a SIP device
A - Incoming SIP request --> B - Internal SIP translation --> C - Outgoing ISDN SETUP -->
