Notes:
1.
Setting Codec 1 to “All” ignores the packetization interval (ptime). The packetization interval
setting defaults to 30, which is the default for all codecs.
2.
Setting Codec 1 to “All” automatically sets all other codec preference fields 2 through 10 to
“None”.
3.
Setting Codec 1 to “Basic” and all other codec preferences in 2 through 10 to “None”, forces
the phone to use only the basic codecs as in previous releases (G.711 u-law, G.711 a-law, and
G.729). If you select an additional codec to use in the codec preferences 2 through 10 fields, those
codecs are added to the list of Basic codecs for the phone to use.
