I currently have a Voip account setup with SIPcity, happy to look at moving it. Though I need to get a Voip phone we can have in the office.
Im not sure why I bother with a land line as no one but call centers call it but may as well keep it. The phone would be handy though as our mobiles dont get very good reception at the home office so we could use the voip instead.
Its not urgent but would be good to get it sorted when you have time
