I am using a 7600 and understand that it uses S40.

Does the handset not support WB AMR?

I am trying to a convert a small music video to play on the phone, but when I transfer it to the phone there is no audio when using the hightest bitrate setting. (WB AMR 23.85)

Using normal AMR I get sound, but it is VERY low quality.
AMR only goes up to 12.2 on Media Converter.

Can anyone confirm that the 7600 does not support WB AMR, or, is there anyway that I can get better sound quality.

Help would be appreciated
