Voice requires a Cisco IOS Software Voice feature set on Cisco 1700 series routers, and a Cisco
IOS Software Plus feature set on the Cisco 2600, 3600, and 3700 series routers.
2
On the Cisco 1700 voice platforms, one or more packet voice and data modules (PVDMs) are
needed to support Voice interface card (VICs,) or voice ports may be missing in the active
configuration. The PVDMs hold digital signal processors (DSPs) that make the VICs fully
functional, and are installed on the motherboard of the Cisco 1700 series. For more information,
refer to
Troubleshooting Unrecognized Voice Interface Cards on Cisco 1750, 1751, and 1760
Routers. On the Cisco VG200, 2600, 2600XM, 2691, 3600, and 3700 series routers, the carrier
network modules (NM-1V, NM-2V, NM-HD-1V, NM-HD-2V, NM-HD-2VE, NM-HDV2) come
with the DSPs installed on the module.

Voice is not supported on Cisco 3631 series router.

The VIC-2DID card can operate in both DID (default setting) and FXS modes on the Cisco 1751
and 1760, and when installed in the NM-1V and NM-2V on other voice platforms. When installed in
a NM-HD-1V, NM-HD-2V, NM-HD-2VE, and NM-HDV2, the VIC-2DID card only operates in
DID mode until the IOS 12.4(3) release when both DID and FXS modes are supported.
5
The VIC-4FXS/DID card can operate in both FXS (default setting) and DID modes on the Cisco
1751 and 1760. On other voice platforms the VIC-4FXS/DID card only operates in FXS mode when
installed in a NM-HD-1V, NM-HD-2V, NM-HD-2VE, and NM-HDV2 until the IOS 12.3(14)T
release where both modes of operation are available.
