Hi. Its not too difficult at all although I had to read the manual for a few minutes to understand how to connect it to my wireless router. Once you connect the phone to your wireless router, check the manual to view the IP address of the phone, this is usually 192.168.x.x where x represents the remaining numbers in the IP address depending on how your network is set up. Once you get the IP address of the TOVO phone then go to Internet Explorer and type in the IP address in the address bar and click go. you will then be prmopted for a login and password to the phone. The default for editing the phones user profiles is login: root password: 888888 This will allow you to access the phones user configuration menu and enter the SIP details of your provider. These are standard settings for any SIP Provider. If you dont know how to configure a SIP phone then you will end up in tears like me lol, but I got there in the end. I use my phone as my main 'landline' number phone with tesco internet phone settings and I've never had any issues with dialing out at all and the voice quality has always been satisfactory, better than mobile quality and slight less than PSTN quality but overall 4+ Star rating on call quality for me. The only issue I have and I dont know why it happens, is that every now and again it doesnt recognise an incoming call. I havent the foggiest why, I can only think that the session is either timing out in someway but if i switch the phone off and then on every so often its seems to recognise incoming calls without any problems at a ll. When I make a call it works 100% every time so I cant complain and thats what I use it for mainly so it works for me. If your looking for a permanent replacement for your landline then personally I'd choose to use the Tesco IPA1000 Adaptor, call quality was excellent for me and no to distinguish between PSTN landline and Tesco Internet Phone call at all. Use a DECT phone plugged into the adaptor and you've got a full wireless solution thats robust and reliable. I used to have that but changed it as It involved having to have 2 mains plugs. But its an extrememly good alternative to the PSTN landline costs. I cut my phone bill down from £200 per year (Virgin Media) to under £50 per year since going with Tesco and I still get as good quality calls. How you set it up is personal preference. Hope this helps. Cheers.
