I don't know how you would do it, but you would require the consent of the other party in order to record the conversation. There is no need to insert beeps at regular intervals.
andThe Telecommunications (Interception) Act 1979 (http://www.aca.gov.au/licence/tir.pdf) prohibits a person from listening to or recording, by any means, of a communication in its passage over a telecommunications system without the knowledge of the person making the communication. A communication includes conversation and a message, and any part of a conversation or message, whether in the form of speech, music or other sounds, data, text, visual images, signals or in any other form or combination of forms. This law does not attach so much to the recording of a telephone call but more the interception. It is the act of interception that creates the offence not the recording. Naturally recording can form part of interception, but it is not the key element of the offence.
Therefore, if you do figure out how to do it, make sure you have their consent to do so.The Courts have generally made a distinction between:
listening or recording using equipment which is electronically connected into or which intercepts radio signals transmitted by a telecommunications system. In this case, the Interception Act applies and the State Listening Devices legislation does not apply; and
listening or recording using equipment which is external to the telecommunications system. In this case, the State Listening Devices legislation applies.
Therefore, listening to or recording of telephone conversations without both party's knowledge using devices such as:
· "double jacking";
· a bug within the telephone mouthpiece;
· a wire attached to the telephone line; and
· an interception device used to intercept car telephone waves,
fall within "interception" prohibited under the Telecommunications (Interception) Act.
