Instead of using AT commands directly i recommend to use the
corresponding frameworkd setting, it's "ti_calypso_dsp_mode" in
[ogsmd] section, possible values are:

"short-aec":        "0083",
"long-aec":         "0283",
"long-aec:6db":     "028B",
"long-aec:12db":    "0293",
"long-aec:18db":    "029B",
"nr":               "0105",
"nr:6db":           "0125",
"nr:12db":          "0145",
"nr:18db":          "0165",
"aec+nr":           "0187",
"none":             "0001",;a=blob;f=framework/subsystems/ogsmd/modems/ti_calypso/;hb=HEAD
