Envision is Hawaii's leader in designing and implementing VoIP PBX solutions. We represent the leaders in the industry: Mitel, Avaya, NEC and Cisco. Businesses are taking advantage of the capabilities made possible by converged multi-service networks, to bring their voice and data systems together. As companies increasingly adopt an enterprise wide view of their voice and data needs, the logic of using a single network becomes clear and the ROI for converged networking is compelling:
Centralized Administration - Managing one network, with one wire to the desktop and with centralized administration, offers great potential for savings.
Lower Costs for Adds, Moves, and Changes - Because the phones on an IP Telephony system are IP devices, it is not necessary to bring in a technician to move a phone. End users can do the job. It can be as simple as unplugging the phone from its current location, and plugging it back in at its new location.
Reduced Toll Expense - By sending intra-company voice calls over the data network or a Virtual Private Network (VPN), instead of the public toll network, converged communication systems can significantly reduce the charges a company pays for long distance calls.
Remote Offices - IP telephony systems extend the features, functions, and applications of a central PBX to serve a branch office location. The remote location receives access to all the capabilities of the main site.
Network Scalability - IP networks can be more readily expanded as a business grows and needs change. Rather than having to add additional station cards, an IP Telephony system can be expanded simply by plugging the IP endpoint into an available switch port on the network.
Envision has the engineering expertise to prepare the network for VoIP with a team of highly qualified data professionals. VoIP networks must be capable of minimizing delay by assigning higher priority to voice packets as they travel across the network. To achieve acceptable Quality of Service (QoS), network elements must be able to tag voice packets with Class or Grade of Service markings, so they will be recognized and given priority as they move through the network.
