In a , I have described how to create a simple macro to have a SkypeMe button in Wiki.

To go a step further, here is a more complete macro that covers all the cases offered by : this Confluence macros is based on the documentation.

Here is the skype macro. It takes two parameter :

  1. action : the skype action to perform (mandatory). Valid values are : "call", "add", "chat", "userinfo", "voicemail" and "sendfile".
  2. color : the color of button (optional). Valid values are : "blue" and "green". When omitted, the color is "blue".
#if($param1)
  #set($imagecolor=$param1)
#else
  #set($imagecolor="blue")
#end
<a href="skype:$generalUtil.escapeXml($body)?$param0">
#if($param0 == "call")
  #set($imagefile="http://download.skype.com/share/skypebuttons/buttons/call_${imagecolor}_transparent_70x23.png")
#end
#if($param0 == "add")
  #set($imagefile="http://download.skype.com/share/skypebuttons/buttons/add_${imagecolor}_transparent_118x23.png")
#end
#if($param0 == "chat")
  #set($imagefile="http://download.skype.com/share/skypebuttons/buttons/chat_${imagecolor}_transparent_97x23.png")
#end
#if($param0 == "userinfo")
  #set($imagefile="http://download.skype.com/share/skypebuttons/buttons/userinfo_${imagecolor}_transparent_108x23.png")
#end
#if($param0 == "voicemail")
  #set($imagefile="http://download.skype.com/share/skypebuttons/buttons/voicemail_${imagecolor}_transparent_129x23.png")
#end
#if($param0 == "sendfile")
  #set($imagefile="http://download.skype.com/share/skypebuttons/buttons/sendfile_${imagecolor}_transparent_98x23.png")
#end
<img src="$imagefile" alt="$param0" border="0"/>
</a>
