COMfortel® 3600 IP

High-end hybrid phone – the perfect complement
to any modern VoIP solution

The idea of centrally controlling the most diverse functions is gaining more and more followers – in a modern office as well as at home. This is exactly where the strengths of the new COMfortel 3600 IP are lying: its pioneering operating concept that even includes gesture commands, it allows you to control everything with absolute ease. Thanks to a faster processor and an extended memory, it performs tangibly better than its predecessor.

Upgrades make it even more personal

The COMfortel 3600 IP uses Android™ as operating system which enables you to operate the display just like a smartphone. What’s more, you can upgrade this phone with apps as you wish – whether they are freely available or natively programmed, such as time schedules or room allocation plans. The high-resolution touch display invites you to personalize it in several ways: five “buttons” can be programmed for immediate touch function, in addition you have five freely assignable screens reserved for apps, icons and widgets.


Actually encrypted in a virtual environment

The COMfortel 3600 IP not only features an integrated VPN client to safely connect and encrypt external extensions (home offices) to the system. Virtual networks (VLAN) are also fully supported. That means your phone and a connected PC may be operated in different VLANs, although physically they share one and the same network. Phone calls are always top priority, of course.

COMfortel Xtension300; key extension for COMfortel 2600/3200/3500xtension300-angedockt-C3600IP

COMfortel® Xtension300

You can attach up to three key extension modules COMfortel Xtension300. In the maximum configuration, you will get 90 additional one-touch destination and/or function keys.

COMfortel® XT-PS

In case your COMfortel 3600 IP is power-supplied via PoE (Power over Ethernet), you’d have to order a separate plug-in power supply unit (COMfortel XT-PS) to connect the first module COMfortel Xtension300. This power pack will supply all further modules. If your COMfortel 3600 IP, however, is fed through the plug-in power supply that’s included in the delivery, an additional power pack (COMfortel XT-PS) is required when connecting a second or third key extension.

Our phone models COMfortel 2600 IP, COMfortel 2600, COMfortel 3200 and COMfortel 3600 IP can be extended with key extension modules. In addition to the 15 keys of the phone, you can end up with 30, 60 or 90 additional function keys which can be programmed in any arrangement required – depending on the phone’s and the telephone system’s scope of performance – as one-touch destination, function, busy lamp, waiting queue and direct line keys. Each key has two levels so that you can control a total of 210 functions at the press of a key.

The module is available in black and white.
