After having the chance to play with and help set up a asterisk server at work, I decided to have a crack at using VoIP at home. I acquired a couple of Snom phones off work, then connected one of them directly to the 2Talk service. This took a bit of fiddling before I got all the setting correct. The next challenge was to set up a asterisk server and have two phones calling. This came with ease just the only problem i struck was getting asterisk to login with the 2talk trunk. The problem I had was my dynamic adsl ip that changes most days. So that idea has now gone, replaced with two stand alone phones that are logged in to 2talk as direct clients.
