Summary of the loop back audio examples from Forum Nokia that are useful for VoIP developers. These examples take the input from the microphone and play the same audio from the earpiece.
For S60 2nd edition (e.g. devices like 6630, 6680, N70...)
Note:This example is only suitable for S60 2nd Edition and for S60 2nd Edition FP2 and FP3 devices. VoIP applications on S60 3rd Edition and newer releases should use an example that uses the Audio Proxy Server (APS) component.
For S80 (i.e. 9300i and 9500)
S80 devices have WLAN but do not support full duplex. Therefore no example exists.
For S60 3rd ed edition (e.g. devices like E60, E61, E61i, R65, E70, N80, N80IE, N91, N92, N93, N93i, N77 )
See the loop-back client example under Audio Proxy Server package in the SDK plugin or in the separate APS package file.
