Dear All, I have a Dell laptop, with Windows XP Professional. I am trying to send a fax via Windows own fax facility (ie not using a fax machine); however, it says there is not fax tone on the other side; ie it fails. I read in Microsoft's article ( http://www.microsoft.com/windowsxp/using/setup/learnmore/crawford_02october21.mspx ), that: "Very Important: Telephone numbers must be in the canonical form in which a U.S. number would appear as +1 (626) 555-1212. If you use even a slightly different form such as (626) 555-1212 or 1-626-555-1212, the dialing rules won't be applied and the fax transmission will fail." Does anybody know what the proper format of a UK tel no is? I follow the above rule; but windows does not accept the sign of + and it does not accept any variation of the above format. Kind Regards, Reza
