Add CODECs to the Capability List
Voice over IP for the Cisco AS5300 43
Under most circumstances, these default files should be sufficient. If you need to, you can add an
additional file (from those stored in VFC Flash memory) to the default file list or replace an existing
file from the default file list. When you add a specific file to the default file list, it replaces the existing
default for that extension type.
To select a file to be added to the default file list, use the following command in global configuration
mode:
Add CODECs to the Capability List
The capability list defines the set of CODECs that can be negotiated for a voice call. Like the default
file list, the capability list is created and populated when VCWare is unbundled and DSPWare added
to VFC Flash memory. The following example shows you the output from the show vfc cap
command, which displays the contents of the capability list:
router#show vfc 1 cap
Capability List for VFC in slot 1:
1. fax-vfc-1.0.1.bin
2. bas-vfc-1.0.1.bin
3. cdc-g729-1.0.1.bin
4. cdc-g711-1.0.1.bin
5. cdc-g726-1.0.1.bin
6. cdc-g728-1.0.1.bin
7. cdc-gsmfr-1.0.1.bin
VFC management lets you add additional CODEC files to the capability list to meet the needs of
your specific telephony network.
Note The capability list does not indicate CODEC preference; it simply reports the CODECs that
are available. The session application decides which CODEC to use.
To add a CODEC overlay file to the capability list, use the following command in global
configuration mode:
Delete Files from VFC Flash Memory
In some instances, you might need to delete a file from the default file list or the capability list or you
might need to revert to a previous version of VCWare stored in Flash memory. To delete a file, you
must identify and delete the file from VFC Flash memory. Deleting a file from Flash memory
removes the file from the default file list and capability list (if the deleted file is included on those
lists).
Command Purpose
default-file vfc Selects a file stored in the Flash memory to be
added to the default file list.
Command Purpose
cap-list file-name vfc slot-number Selects a codec overlay file to be added to the
capability list.
