"As a freelancer I treasure being able to spend time with my family whenever I can. Having said that, it is important that my customers don't realise that my office is at my home. A system that makes it absolutely clear from the ringtone whether an incoming call is for business or is private was therefore just as essential as a separate overview of charges for private and business telephone calls. This isn't the only requirement that the COMpact 4000 fulfils: my company has its own voice mailbox and fax box – and so does every member of the family. So now everyone can feel responsible for operating the door intercom and door opener. The best thing is that this system makes me more independent – an app downloaded onto my phone makes sure of it. Thanks to the app PBX Manager, I can conveniently control important functions and retrieve both voicemails and faxes, all while out and about. What's more, I also treated myself to the COMfortel 2600 IP – it is extremely comfortable, can create call connections with a single keypress, forward calls to another telephone or my mobile telephone and change the announcement on my answering machine. And my family? They are delighted to have the freedom of the cordless COMfortel M-510 telephone and, of course, also that they can call each other in the house free of charge. Incidentally: outside of my business hours, in the evenings and at the weekend, the system is switched to sleep mode. This switches off the energy-saving displays and LEDs, but they still remain active."
