Using Call Features Chapter 3 Managing Linksys 900 Series IP Phones Selecting the Audio I/O Device and Line The SPA900 Series IP phones provide three audio I/O devices: • Handset • Built-in microphone and speaker • External microphone and headset Only one audio device can be selected at one time. The speaker is selected by pressing the Speaker button, while the headset is selected by pressing the Headset button. When Speaker or Headset is selected, the corresponding LED is steady green. The handset is selected whenever it goes from the on-hook to the off-hook position. Selecting or turning off an audio device is equivalent to an off-hook action, while turning on an audio device is equivalent to an on-hook When there are no active calls, all audio devices are deselected. When any one of the calls becomes active, the handset is selected automatically as the audio device if it is off-hook, else the speaker or the headset is selected according to configuration: the user can configure whether speaker or the headset device has higher preference.] A line is selected by pressing the corresponding line key. To make or receive calls, the user must select a call appearance (line key) or an audio device. If the user selects a call appearance, then an audio device is selected automatically according to user preference setting. If the user selects an audio device, an idle call appearance is selected automatically in the order L1, L2, L3, and L4. The user may switch between audio devices while the call in any of the active states. A new call appearance is selected automatically when the user presses the conf or xfer soft key. The 900 Series phone tries to pick an idle call appearance that is on the same extension as the last active call. If that call appearance is not available, the phone tries to pick a call appearance whose extension has the same proxy server as the last active call. Finally, if that fails, the first idle call appearance is selected, in numeric order (L1, L2, L3, L4). Making Calls There are two steps in making a call: 1. Selects an audio device 2. Dials the number The 900 Series phone lets the user perform these two steps in either order. In other words, the user can select an audio device either before or after dialing. The 900 Series phone supports two types of dialing: explicit or implicit. Explicit dialing occurs when the user performs one of the following actions: • Enters the target number digits one by one • Enters the speed dial assignment of the target number • Selects an entry from a directory, and presses the dial soft key • Presses a dedicated key, such as the Voice Mail key 3-12 Linksys 900 Series IP Phone Administrator Guide Document Version 3.0
