VoIP client development

VoIP overview on S60 platform (23 min)
The webinar, held on December 13, 2007, covers the S60 platform and device features that are essential regarding VoIP. Most of the S60 3rd Edition phones include built-in internet telephony application that the end-user can make VoIP calls with but it can also be utilized from 3rd party applications.

Note (updated June 12, 2008)
VoIP developers should use  the Audio Proxy Server (APS) API only on  S60 3rd Edition  devices. APS will be replaced by VoIP Audio Service  (VAS) APIs.  VAS APIS should be used on S60 3rd Edition, FP1  and later devices. APS and VAS APIs are available in S60 SDK plug-in packages.

This webinar introduces a new VoIP profile provisioning method "File provisioning API" for VoIP that enables 3rd parties to create SIP based VoIP settings from a file to a S60 device.

S60 Platform: Full-Duplex Audio Example v2.0
This C++ example application plays and records audio simultaneously, reading from the microphone and writing to the earpiece/speaker, creating a local audio feedback loop. Audio is processed in encoded format, using real-time encoding/decoding support from audio hardware. This example can also be used for creating VoIP applications on S60 2nd Edition, S60 2nd Edition FP2 and FP3. Main classes: CMMFDevSound, MDevSoundObserver.
