In the case of parallel call signaling, incoming calls are also signaled on one or more external devices (e.g. ISDN telephone or mobile phone), and can be picked up there as well.
You can integrate a mobile phone in your system with SwyxIt! Mobile. If you want to use this feature, SwyxMobile has to be available and it must be enabled and configured by the administrator (see chapter SwyxIt! Mobile and MobileExtensionManager).
