I heard the rumor that even if you specify G.711 as intra-region codec, you'll have to disable G.722 in Enterprise Parameters and Service Parameters. Otherwise, G.722 will be chosen.
I tested it in the lab. That was not the case. If I explicitly specified G.711 as intra-region codec, the phones will always use G.711. Do we still need to disable G.722? Thanks!
