Our application correctly handles GSM calls and the CTelephony Tel. application runs in the background of our application.
I would like to control the audio of the currently active GSM call, such as Activate/Deactivate the loud speaker and control the volume directly from our application.
Are there any API that will allow me to control the volume and the speaker when in a GSM call directly,
i.e Loudspeaker control without using the APS Server and volume control without using the CR keys.
I also know there is an extension API that allows the control of Mute/Unmute when in a call but couldn't find anything similar for volume and speaker.
Thank you for all of your help, and sorry if my question has an obvious answer, I looked for a while on the forums without finding such an API, but it feels it should exist,
