ESTOS is a german company that is an independent software vendor for Unified Communications components. They have developed a small TAPI application that lets you dial any number using Communicator. I have used it for about a year for Communicator and it works great. I have now tested it for Lync and it still works great and is very easy to use. This is how it works:
- Highlight any phone number from the web, Outlook, IM session, wherever you can find a telephone number
- Press your chosen hotkey, by default it is F8
- Lync 2010 will call the chosen number
Untill now it has been a free tool, now you have a free trial for 45 days. One user licence is 29,00 €. I recommend you try it in your Enterprise Voice deployment. You can download it here
