FWD is in general very stable and developing their services all the time, remember however that FWD not is a commercial service. Also they don't offer you any possibility to call PSTN no's beyond the access to toll free numbers.
First the way, how you can connect Asterisk to FWD by using SIP. This is the common setup used, since the IAX gateway is fairly new and considered beta.
Example 1. sip.conf
register => 12345:password@fwd.pulver.com [fwdnet] type=friend secret=password host=fwd.pulver.com dtmf=inband allow=ulaw |
Example 2. extensions.conf
exten => _**393.,1,SetCallerID(Your Name <12345>) exten => _**393.,2,Dial(SIP/${EXTEN:5}@fwdnet) exten => _**393.,3,Hangup |

There are various ways of obtaining help with FWD: 55555 is the volunteer welcome line, 514 is the Virtual Coffee House, 611 is the Technical Helpline (limited availability) or just use the user forums on their website, which also can provide you with a lot helpful information.
