Phones with SA Buttons

SA Ring. Use these buttons to make and receive both inside and outside calls. To call an inside number, dial only the extension. For outside calls, dial a dial-out code (usually a 9) before the phone number.

SA Voice. Use this button to make inside voice-announced

calls and outside calls, and to receive both inside and outside calls. Voice-announced inside calls do not ring—yourco-worker hears your voice over the speakerphone instead. To make outside calls, enter a dial-out code (usually a 9) before the phone number.

SA Originate Only. Use this button only to make calls; calls do not come in on this button. To make an outside call, enter a dial-out code (usually a 9) before dialing the phone number. This button is set up by your company to make either inside ringing or voice-announced calls (not both).
