Possible to establish call and have some prerecorded audiofile played to the call?

[deviation]

Hi all,

I am currently doing some research and I was wondering myself if the following scenario is possible:

an Symbian app will establish a phone call and as soon the call get answered a custom audio recording that is provided by the app will be played. First after the recording finished playing the user is able to start speaking to the mic.

Appreciate any comments on this. Thanks in advance

Check CTelephony for call establishment and monitoring, and Audio Proxy Server (APS) for audio paying into the call uplink.
