A voice connection requires both a voice network module and a voice interface card. Voice interface
cards are not installed directly into the router chassis, but must be installed in a voice network module
to function. At least one other network module or WAN interface card must be installed in the router
chassis for any desired connections to the IP LAN or WAN to function.
