Hi Alex,

Its the user ID which is causing your problem. If you just add the following
<param name="total-modems"    value="5"/>
to your configuration you will get five /dev/FS* devices if you run as 
root, but none if you run as freeswitch. This ought to be fixed. I think 
the device names are a bit questionable, too. Calling the /dev/FS/modem* 
or even /dev/FS/t31-* might increase flexibility for the future where 
more device types might be needed.

The use of the T.31 modems needs adding to the wiki, with sections on 
Linux use and on Windows use. Windows use is far from obvious, as you 
need to install com0com to provide the loopback virtual serial port devices.
