side tone sound for sdk client apps??

[boxer]

I'm implementing what amounts to a radio type voice communication system using the SDK. I've figured out rudimentary ways to make the soundscape replicate UHF/VHF radio transceivers (half-duplex sound, ambient noise mixed with incoming voice, mic clicks, multiple signal interference noise and so on) without needing to add a custom FMOD system object. Basically I'm adding other sounds at the same time as ones played by the sdk code via APIs from the other libraries I'm using (wxWdigets in this case) and then playing with the volume levels of the sounds delivered from the sdk for muting and so on. This all works surprisingly well. But...

One thing the testers are asking for though is side tone -- the sound of your own out-going transmission from the mic fed back into your own speakers/earpiece at a low volume level as you are speaking (PTT depressed). This is a typical feature of real-world voice communication systems of all sorts (radios, phones, etc.).

Is there any reasonable way to get the effect of side tone without learning how custom FMOD objects work?? Any hints, tips and tricks welcome -- thanks!

Can I bump this one?? Any ideas??
