Dear Fabio,

Do you have an idea on what Nokia E SIP client uses for sound and
codecs?...is it it APS?...

The devil demostrate itself trough the Nokia built-in SIP client.
PJSIP must became even better on S60 platform, and it can!

The built-in SIP clienti use, as far as i remember, AMR-WB at 12kb and
for the sound i don't know because it'a a built-in ROM application and
so maybe could even use CMMFDevSound directly for what we know.

For third party application APS it's the best choice for all S60 Symbian
9.x FP0, FP1, FP2 releases.
From FP3 the new VoIP Audio Services API must be used, but there are
still no FP3 release out-of-the-market and only the first FP2 are
getting out during this months.

Hi,

Both these problems are mostly solved now. (I've included the files)

The only problem I have left, is that the encoded sound sounds metallic.

I followed most of the rules concerning CPU load on windows mobile
