David Steinberg commented on ASTERISK-13145:
--------------------------------------------

@Mat I don´t think this is possible, but you can use a different Codec like iLBC. Our Cisco phones support: G.711a, G.711u, G.729a, G.729ab, G.722, iSAC and iLBC audio compression codecs. I think iLBC is most promising https://de.wikipedia.org/wiki/Internet_Low_Bitrate_Codec
