With your ISDN telephone, you've become used to some luxuries that you wouldn't want to miss after switching to a VoIP line. You'll be looking for a VoIP phone that offers you a wide range of functionalities, top quality "made in Germany", state-of-the-art design, and many technical highlights. Look no further – here's the Auerswald COMfortel VoIP 250, a stand-alone phone that you can hook up to your network, no PBX system required.

The telephone's large backlit graphic display and the softkeys make it extremely easy to operate right from the start. You can use the 15 programmable function keys with multicolour LEDs for a number of tasks: Programme them as abbreviated-dialling keys, and you can make calls at the touch of a key. The keys can also give you quick access to useful functions such as Call Forwarding (unconditional, on busy, no reply) or call waiting. If required, up to three COMfortel Xtension30 keypad extensions can be added, with 30 keys and LEDs each.

And here is a little bonus for frequent callers: COMfortel VoIP 250 lets you connect a wireless headset (DHSG). Those who have the convenience of a self-powered LAN can do without an additional power supply thanks to "Power over Ethernet" (PoE). And if the network port is already occupied by your PC, simply route the PC's network connection through the telephone, with its two Ethernet ports.

The telephone's modular concept lets you add up to three COMfortel Xtension30 modules for extra function keys*. You can fit them on either side of your telephone. With all modules fitted, you have 105 function keys available. Each key has 2 levels offering a total of 210 functions available upon key stroke.

The COMfortel VoIP 250 is available in the colours black, dark blue and light grey (white).
