Based on a little sip debugging, these appear to be the supported audio codecs on the Nokia E65

• AMR
• PCMU
• PCMA
• iLBC
• G729

The above is the order they’re presented in, so it’s probably also the order of preference.

Note: These are for VOIP calls only, the media player supports a much broader range of formats.

Update (15 Oct 2007): Nokia have released a simple application called SIP VOIP Settings which now allows you to change the preference order of codecs.
