>Does not work. Error is "Exception code OLE lDispatch 0 for Skype4COM.Skype.1: CALL: Unrecognised identity.."

What is the number you're entering? The following works just fine for me:

loSkype = CREATEOBJECT("Skype4Com.Skype")
loSkype.PlaceCall("+494068267082")

Before testing change the number, unless you want to talk with my fax machine. <g>
