Use Softphone in the Road Warrior mode when you want call control signaling and voice media to flow over the IP network between the softphone and Communication Manager.

You also can take over an IP telephone. Typically you would not have a different extension for your softphone. When you log in, the softphone takes over the existing telephone extension (turn the DCP or IP telephone off). During this time, that DCP or IP telephone is out of service. This is accomplished if, on the Station screen, the IP Softphone field is y.

To illustrate, add a softphone in Road Warrior mode at extension 3001. Except for single-connect IP telephones, you have to actually administer two extensions for each Road Warrior mode.
