Your advantages in detail

When operating as an ISDN system telephone, the COMfortel 2600 pulls out all the stops when it comes to user convenience: designed with ergonomics in mind, all the COMfortel 2600's functions can be accessed from the keyboard, directional pad or simply by touching the high resolution backlit TFT colour display. The support feet can easily be adjusted to ensure the best reading and operating position in every situation.

Simply plug in a standard SD card (up to 16 GB recommended) to discover even more options, such as assign images to telephone book entries, upload wallpapers and ringtones and switch on the answering machine. You can even assign a special announcement to every home or business entry in your telephone book.

Everything you'll need in daily life is covered, from the recording and memo function, to the headset connection, to the USB port, because you can control everything from your PC, from configuration to editing telephone book entries, easily and conveniently. For example, you can start a call directly from your saved Outlook contacts with a single click.
