Just add in the extra channels: fxoks=9-32.  Be sure to check the
order the cards are loading with zttool.  If the 2401E is loading
first, it will actually be channels 1-24, and the 800 will be channels
25-32.

Also, test to make sure your machine is capable of this setup.  Each
of these cards will generate 1000 interrupts per second.  Most modern
motherboards should be able to handle this, but some older ones may
choke under this load.
