[Freeswitch-users] MC8704 on mod-gsmopen

[Francis]

That's the tricky bit. The data sheet does say USB:

.. but voice is over I2S and I don't know if that will work with the USB 
adaptor, or if I'll have to plug it directly to the motherboard to gain 
access. Can mod-gsmopen use the I2S interface, or is it strictly USB only?
