COMfortel® 2600

This ISDN system phone follows your orders instantly –
just put your finger on the large TFT colour display

Why should a modern ISDN system phone have to depend on softkeys to use the display? The all-new COMfortel 2600 proves that progress is unstoppable. Its illuminated touch display ensures easiest control: in addition to keys and control pad, the display awaits your commands to activate functions directly. Superior ergonomics also governed the design: the attractive two-tone cabinet features large tilt feet so that perfect visibility and operating angle are always ensured. 
Its large illuminated TFT colour display with touch control highlights the level of convenience introduced by the new COMfortel 2600: at 4.3” (10.9 cm) it offers a very high resolution.

To see how versatile this new model is, simply insert a customary SD card (up to 16 GB recommended): it allows you to allocate pictures to individual phonebook entries, arrange for a wallpaper image and upload new ring tones.

Inserting the SD card also activates the answering machine which can be conveniently controlled via the touch display and function keys. Since you can allocate individual messages according to caller and type of call, each entry in your phonebook may receive a special announcement – depending on whether it’s a private or business nature. Also, it gives you a practical recording and memo function. Since you don’t have to type a PIN number to access your message box (your mobile number is identified automatically), you can easily be updated on the move.

A separate socket lets you connect a corded headset, and a wireless DECT Headset will easily extend your radius up to 50 meters. The built-in USB port instantly connects with your PC: at the click of a button, you can dial directly from your Outlook contacts, and when someone calls you, you can immediately see on your monitor who’s calling. You want to configure your phone or manage your internal phonebook entries? Everything can be easily done via PC with great comfort.
