You're not landing in [from-pstn].  Incoming calls are landing in 
[default].  That's not a problem in extensions.conf, that's a problem in 
dahdi.conf for those channels.  They're not in the right context.

That'll let you dial US toll free numbers out the channel specified by 
dialing 9 or 8.  It will playback a message and then generate a 
congestion tone if some other number is dialed.
