Your advantages in detail

No matter whether you use it as a standard SIP or IP system telephone, the COMfortel 3600 IP is the ideal supplement to modern VoIP solutions. With its pioneering operating concept, which includes gesture control, this model can be operated not only by keyboard commands, but also like a smartphone, from its high-resolution 5 inch colour touch display!

To synchronise your calendar, contact data and e-mails directly with your telephone, simply use the push services from your Google™ account, the TelekomCloud or a Microsoft® Exchange account. This keeps your telephone address book up-to-date with your Outlook address book, and you can see your schedules at a glance via a widget.

Five freely assignable screens provide enough space for more apps, and you can always connect your headset, whether it's cordless (e.g. a EHS device) or not. Up to three key extension modules (COMfortel Xtension300) can be added to the COMfortel 3600 IP to extend its capacity to 105 function keys. It also has several dynamic keys that can be programmed directly in the display as touch function keys.
