Hello all. After much struggling for about 10 hours now, I have got my Plustalk service working perfectly on my ATA. Most of my struggling was down to me not knowing anything about VoIP. I set up an account with sipgate.co.uk as well. I used the sipgate account to prove that my kit worked and have now got both accounts working together. Sorry to hear about all the troubles some have - I suppose I have been lucky. Half of the settings that I was reading about I didn't need to use. My ADSL router is a Siemens 5830.
