Configure the Voice Codecs
A codec resource is considered allocated if it has been included in the SDP codec list of an active call, even
though it eventually might not be chosen for the connection. Negotiation of the optimal voice codec sometimes
depends on the ability of the Cisco IP Phone to match a codec name with the far-end device or gateway codec
name. The phone allows the network administrator to individually name the various codecs that are supported
such that the correct codec successfully negotiates with the far-end equipment.
The Cisco IP Phone supports voice codec priority. You can select up to three preferred codecs. The administrator
can select the low-bit-rate codec that is used for each line. G.711a and G.711u are always enabled.
