Other Routers on the Network
If the path between endpoints of a voice call travels through intermediate routers, configure those routers for VoIP traffic, as described in the section “Configuring FXS Interfaces” earlier in this guide.
You need to configure POTS or VoIP dial peers on an intermediate router only if that router also has voice devices attached to it.
Checking FXS Configuration
If you configured VoIP dial peers on your router by following these examples, you can place calls from that router to telephones on the remote routers (using just the extension if you configured number expansion). If you have trouble placing calls, ping the remote router to make sure you have IP connectivity, or use the show
Note Refer to the section “Tuning Parameters for
Configuring FXO Interfaces
FXO interfaces provide a gateway from the VoIP network to the analog PSTN or to a PBX that does not support E&M signaling so that users can reach telephones and fax machines outside the VoIP network. Figure 18 shows a typical FXO gateway attached to the West router.
