G.711 with either A-law or µ-law dynamic companding is supported, they are referred to as PCMA and PCMU, respectively, in our list of codecs. G.729 use is possible if you install: http://www.linphone.org/eng/documentation/dev/bcg729.html Please note that the use of G729 remains governed by a patent license to be acquired from G729 patent holder representatives.
