Peter,

Can you connect on IRC (irc.freenode.net #freeswitch)? I'm gmaruzz there.

Can you restate your problems? I've lost connection :)

with snd-dummy custom you can create *one only* snd-dummy instance, so
*one only* fake soundcard. If you create more, will not work. But with
that one fake soundcard you can use 64 skype client instances, all
with the same soundcard hardware device (hw:n).

with original snd-dummy you can create a max of 8 instances, so 8 fake
soundcards, and with each fake soundcard you can  use a max of 8 skype
client instances.

use the hardware devices, not the default devices (use the "hw:n")
