With our Phone APP, you separate private from business and allow your contacts to reach you through a number (One Number Concept). Take your PMG telephone system flexibly and regardless of location on trips. Make a call with your office landline number instead of your private mobile number. See the telephone and presence status of your colleagues, toggle, or go into consultation and play the caller on your professional waiting box while you add another call and then initiate a 3-party call. Make calls from your contacts and decide from case to case, whether your call via CTI (callback function, recommended for calls from the car), directly via VoIP (recommended for good and constant Internet connectivity eg wifi) or as a normal GSM call with your Mobile number.
