Example VoIP Configuration
Introduction
This section shows an example of how to configure VoIP. Figure 8 illustrates how
two PathBuilder S24x, 26x, and 27x switches can support long distance telephone
service between a small branch office and a head office, over the company’s Intranet.
Figure 8. VoIP Configuration Example
Node 100 and Node 200 are configured with FXS Voice ports. The branch office
phone can be configured as an extension phone number off the head office’s PBX.
The nodes connect to the Ethernet LAN and therefore an Ethernet port must be
configured for each node. The associated IP interface parameters must also be
configured. To carry voice traffic over the IP network, the SoTCP parameters must
be configured.
