Functional Notes
You can enter as many CODECs in the list as necessary by repeating the codec command while in the
Voice CODEC List Configuration mode (refer to the Usage Examples section of this command).
Order is important when creating a CODEC list. The interface attempts to use the first CODEC in the list to
negotiate a call. If the first CODEC negotiation is unsuccessful, the interface uses the second CODEC in
the list and so on. If this process is unsuccessful, the call will fail.
CODEC lists do not take any action until they are applied to an interface. For information on applying
CODEC lists, refer to the codec-group <name> command in the command section of the interface to
which you want to apply the list.
