The top row of the keypad includes hold, redial, and the rather charmingly labelled goodbye' key. As well as ending an active call the goodbye' key and also exits open menus. Just below the screen, a set of four directional controls enable you to navigate the menu system. Buttons at the right of the phone includes keys to open the options menu, switch to speakerphone mode, begin a conference call, transfer calls and switch between lines. Not all of these symbols are immediately obvious, but there's nothing too complicated here.
The phone's menu system is easy to navigate. There are eight basic menus. Call forwarding settings enable you to select the circumstances under which the phone will forward calls, such as in response to a busy tone, and enter the number you wish it to forward to. A preferences menu enables you to set your time zone, set ring tones, add speed dial numbers to the phone's programmable keys and switch the phone into headset mode.
The Phone Status menu displays useful information like its IP address and recent error logs. There's also a password-protected Admin menu that replicates many of the configuration options available via the web interface, although it's a much less convenient way of modifying the phone's settings.
We had some difficulty actually finding the administrator password required to access the web interface to configure the phone for use on our network. The accompanying CD includes basic and advanced installation guides. Unfortunately, neither of these includes the administrator password. The basic guide referred us to the Aastra IP Phone Administrator Guide, which we had to download from Aastra's site to find the default user name and password combination of "admin" and "22222".
The Network settings display shows your DHCP assigned address. Alternatively you can set a fixed IP address, as well as any required NAT, STUN server and other network settings. If your network uses DHCP, you probably won't need to change anything here.
The Global SIP settings enables you to configure common settings for all lines that you wish to direct to the phone, up to a maximum of six. Each line can also be configured separately. Initially, to get the phone up and running on our Asterisk server, we had to use the SIP configuration options under Advanced Settings.
Rather unclear documentation and a web interface with minimal annotation will make this a rather daunting task, particularly for novices and a certain amount of trial and error was involved. However, configuration shouldn't take too long if you're familiar with VoIP systems.
