    Hi,

    In 3rd sdk onwards CTelephony helps in call handling but encrypting a call is entirely different,because encryption can be done on data only. So what I think you need to catch the raw data befor they convert into packet. I am not sure whether there is any api for this or not.

    Most third party voice call encryption solutions depends either on data calls or use a dedicated hardware device such as custom bluetooth headsets to achieve this.

    However i guess it may be possible to add systemetic noice to the telephony uplink using public api's (VAS/APS) and you should be able to remove the noise on the receiving end. This in effect will scramble the voice data and make it hard for the depicher, though i am not sure of the cryptanalysis strength of this.

    Hope that helps,
    VJ
