Mike,

I suggest emailing Skype's CEO (josh.silverman@skype.net) drawing his attention to Ofcom's Amended General Condition 17 for 03 numbers (see www.ofcom.org.uk/consult/condocs/numbering03/statement/) that requires that calls to them must be carried at the same rates as calls to 01/02 numbers.  I suggest you also copy your email to clive.hillier@ofcom.org.uk, geoff.brighton@ofcom.org.uk, gareth.davies@ofcom, steve.unger@ofcom.org.uk and stuart.mcintosh@ofcom.org.uk  Also copy in Skype Director of Telecoms (stefan.oberg@skype.net) Director of Core Technology, QA and Security (Ott.Kaukver@skype.net) and Skype Director of User Experience & Communications (Suchi.Mukherjee@skype.net).

It's possible that they do include 03x numbers but whomever updated their webpage isn't any the wiser so just put the "norm" 01 and 02 number only speech.

Another similar VoIP provider that I am with charges calls to 01 and 02 numbers at a low rate (just short of 1p a minute), but 03 numbers at a slightly higher rate (1.5p a minute). When I queried them as to why this was, they said that it was due to their supplier of 01 and 02 numbers provided them with a great rate for 01 and 02 numbers (hence the 1p a minute), but that they had to fall back to BT for 03 numbers (1.5p a minute).

Perhaps this is why Skype doesn't include 03 numbers in their deal - they can't get them at the same discounted rate as 01 and 02 numbers?
