Asterisk - multiple sound cards for CONSOLE/dsp

Have a slightly unusual request.
I have two sound cards installed in my Asterisk machine and I want to configure and use both as a SIP phone.

eg:

exten => 101,1,Dial(CONSOLE/dsp) --> /dev/dsp
exten => 102,1,Dial(CONSOLE/dsp1) --> /dev/dsp1

Is this possible? Can I have more than one CONSOLE sound card both being used at the same time?

Has anybody else tried to do this before? If anybody knows for a fact whether it can or cant be done please post it as I dont want to waste anymore time on this if it is not possible.

Even if you dont know how to do it but know that it can (or cant) be done please post this as I am giving up hope that it can be done.
