The following table describes the labels in this screen.
7.4.11 Codec Priority
When the V500 makes a SIP call, it negotiates the voice codec (coder / decoder) it uses for the
call with the SIP server. Both devices must be able to use the same codec. You can set two
codecs for the V500 to use. If the SIP server cannot use the first codec you set, the V500 tries
to use the second codec. If the SIP server can use neither the first codec nor the second, the
V500 tries to use the third.
