Buy phone from SIPGATE, they connect directly to the router, are cheap (the phone itself), no monthly fees, calls to SIPGATE clients or contacts are free, sound quality is excellent, free UK number, etc. etc. Otherwise buy PAP2 adapter from ebay for about $30 and get two phone points which can be configured to SIPGATE or other VOIP account providers. I have used both (for home and business) and I have had excellent service for past three years.
