Implementing proprietary audio protocol using tcp/ip sockets

I have documentation about a two-way audio protocol that describes the communication between a microphone/speaker network device and a computer using tcp/ip sockets. I also have a dump of raw tcp/ip packets of this protocol taking place.

The audio protocol packets contain ADPCM (8KHz, mono, 4 bits/sample).

What I need is:

- Streaming audio from the iPhone/iPad's microphone to the microphone/speaker device's speaker

- Streaming audio from the microphone/speaker device's microphone to the iPhone/iPad's speaker

The challenges:

- Understanding the protocol (helped by documentation and reverse engineering the raw packets)

- Converting the stream from the iPhone/iPad microphone into the correct format

- Decoding the stream from the microphone/speaker device and play it on the iPhone/iPad

The platform is iOS 4.3 and higher (so must work on iOS 4.x, iOS 5.x).

Also, if you don't have any knowledge of objective-C and iOS but can implement a (partly) solution for Linux, OSX or Windows in C or C++, we can probably make a deal also.

Please only serious bids,

I have 20+ years experience in C/C++ and 15+ years in Java. I can complete this project with high quality code. Not knowing more about the details of the protocol, my estimate may need to be adjusted.
