Xblue digital and VoIP phone systems’ features – like hold, call transfer, conferencing and intercom – are already set up and ready to use when you first turn on your new system. Even voicemail is ready to receive messages on every phone as soon as the phone is connected to the system. Xblue’s systems are hybrids, supporting both standard telephone company lines and internet-based VoIP lines. The two types of lines can be used at the same time. The company also offers cloud VoIP line service with no contracted period or early termination fee.
