No third party software needed. You do need to have a few things done though within your pc;
Install 'Cisco Telephony Service Provider' found in the 'Install Plugins' section of the CCM webpage. Accept most defaults, appropriate language, and no to multiple instances. Restart your machine after the install.
After reboot, goto control panel and the 'Phone and Modem Options' and here you will edit your default locations to accomodate your dialing needs. After that you will go into the Advanced tab.
In the Advanced tab, double click the 'ciscotsp001.tsp'. Go to the 'user' tab, and put in your info such as domain account and password.
goto the CTI manager tab and put in the appropriate IP address for the call manager, no back up option.
within the CCM user/global directory for each user make sure 'enable CTI application use' is checked. Make sure you devices are associated with your active directory name.
Open outlook, and go into your contacts, right click on a contact and select 'Call Contact'
Select dialing options, at the bottom, and at the bottom where it says 'Connect using line', hit the drop down arrow and you should see your phones line to select. If you do not, select H323. Select close and repeat the Dialing Options process to see your line.
Hope that helps!
