Cisco VIC To make a voice connection, the router must have a supported VIC
installed. The router supports up to three cards. You can either order
the cards when ordering the router, and they will be installed for
you, or you can order the cards separately, after receiving the router,
and install them yourself. You must install digital signal processors
(DSPs) to use VICs in the router.
