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. Fabio
