Cisco has just released a Communicator plug-in, with this plug-in you can do clik to call. it’s a TAB plup-in.
This is a Cisco softphone intergration and by using this you will move all your voice Communication to the “Cisco world”. (there must be some pro/cons when doing that ;) )
I haven’t testet it jet, but if I get the chance, I will post a new blog about it
