you used to be able to use **282(bvnumber)@fwd.pulver.com as an open sip. *393**282(bvnumber) also worked too. However, it seems that BV has restricted access to sip calling. It looks like they will now only accept calls that originate from FWD and not from outside. So basically you have to be logged in to FWD either with the communicator program or with your ATA in order to call a BV custormer. Check out this post on FWD's forum:
