During the pre-connection phase in SIP and ISDN, it is possible to send progress tones and sometimes messages generated by the carrier/ PBX (e.g. `this is a premium rate number, you will be charged if you proceed', or `this extension is disabled') before the caller is charged. Can this be implemented on Android, so that a call can be rejected with a recorded message (stored as an audio file in the phone) during the pre-connection phase, or perhaps so that the caller can be allowed to hear a customised ringing tone? It can already be done easily with Asterisk and other SIP applications, but it would be interesting to do it from the handset too.
