Dialo

Dialo is a call manager, allowing you to select and dial any phone number directly from your PC. It works with Cisco IP phones connected to your local network and it can send several commands such as dial, end, hold on each extension you select. Select the phone number in any application, copy it, then press Dial in the program window; that's all you have to do. Four memory presets, M1 - M4, can store four Speed Dial numbers for easy access. Furthermore, you have the possibility to control the volume of the speaker, ringer, headset or handset, and you can also Mute the microphones.
