I am a newbie, and am also trying to get this device to work.  I have 
it working well enough that I can manually dial the extension of the 
FXO and get my PSTN dial tone via VOIP.  This seems to work reliably 
and I have been testing it with softphones for several days.  Also I 
have the FXS working ok  so yes you can use them both independently.

My current struggle is to figure out how make an appropriate dialplan, 
so that dialing a regular old 7 digit (or 10) phone number will route 
the call through the FXO.

This appears to be a relevant thread, but I am still deciphering it.
