Integrating Asterisk with both Exchange 2007 and LCS

Has anyone managed to integrate Asterisk with both Exchange and LCS? I’ve found the following two links which show how to do them induvidually but I wan’t to use them both at the same time.

The top link uses sipX and the bottom uses SER.

I’ve also found the following software which I’d like to know if anyone has used?
