Chapter 4 Configuring Voice-over-IP FXS-to-FXS Connection Using RSVP The following example shows how to configure VoIP for simple FXS-to-FXS connections. In this example, a very small company, consisting of two offices, has decided to integrate VoIP into its existing IP network. One basic telephony device is connected to Router RLB-1; therefore Router RLB-1 has been configured for one POTS peer and one VoIP peer. Router RLB-w and Router R12-e establish the WAN connection between the two offices. Because one POTS telephony device is connected to Router RLB-2, it has also been configured for only one POTS peer and one VoIP peer. In this example, only the calling end (Router RLB-1) is requesting RSVP. Figure 4-1 illustrates the topology of this FXS-to-FXS connection example.
