Basic Functions
Park orbit
snom4s provides its customers with the opportunity to set up parking orbits on the media server, where calls can be parked and picked up. The option 'Park Orbit' enables the phone to provide this feature.
Suppose key P4 is bound to orbit1@my.proxy.com. The LED on this key now displays the status of calls, if any, parked on this orbit. A blinking LED indicates that a call is parked there; the user can pick up this call by pressing P4. Pressing P4 during a call will park it at orbit1@my.proxy.com until the same or another user picks it up later. The caller will hear the holding music. This feature is useful for call center environments and all places where there is a great inflow of calls and some kind of queuing is required to manage them.
Voice recorder
This option can be set up with a valid voice recording account. Suppose that vr@my.proxy.com offers voice recording and is bound to key P5 on the phone. Its usage is as follows:
During a call, the user is able to record his conversation with the other party by pressing P5. Pressing button P5 again will end the recording process.
The recorded media can later be listened to by accessing the recorder account vr@my.proxy.com.
This feature is also useful for recording short messages or memos to self. By pressing P5 in the idle state a user can record an important message to be listened to later.
The same applies to the recording of a debate or discussion, to keep audio minutes of a meeting, or to record an important conference call hosted on the phone.
DTMF
In H.323 mode, this line type offers the ability to set up the programmable keys as additional function keys concerning PBX functionality controlled via DTMF key codes. Upon a key press to the programmable key set up as DTMF line type, the specified number sequence is dialed as DTMF key codes.
Main Menu
By pressing the MENU key 
in the idle state the main menu is invoked. The following submenus are available: Phonebook, Call List, Deny List, Tones, Settings, and About.
