Voice and Data network convergence has resulted in IP Telephony- a network based phone system that runs on the same LAN as your data network. Also known as VoIP, this technology is essential for Unified Communications which allows for the consolidation of voice, data, video, and mobile applications on your network. The integration of voice and data technologies can reduce operating costs while offering a great range of features and benefits, such as Unified messaging (voicemail integrated with e-mail). IP Telephony is scalable and allows for easier administration for moves and changes. In addition to providing the physical network infrastructure for IP Telephony, Advanced Data – a Cisco Select Certified Partner – can also provide the hardware to go with it.
