IT Survival Guide: Voice Over IP Makes Convergence Possible
Read the Original Article at InformationWeek
Voice Over IP isn't the future, it's here: 47% of companies have IP PBX deployments under way, and an additional 29% are evaluating or testing the technology, according to Forrester Research.
What's the draw? VoIP started as a way to cut telecommunications costs. But while avoiding toll charges is still a factor, along with simplified adds, moves, and changes, it takes a long time to pay for a new IP PBX based on those savings alone. Rather, vendors are now positioning VoIP as a vital cog for unified communications and fixed-mobile convergence. If you haven't put an IP PBX in place, you'll miss out on productivity enhancements that could provide a competitive edge.
Unified communications is all about merging collaboration tools, like calendaring, e-mail, and instant messaging, with voice. For example, e-mail can be read to users from the voice-mail system, and voice mail can be accessed via e-mail. A user's presence status can be viewed before a call is placed. By meshing a variety of communications mediums, employees can be reached through the most appropriate method.
Fixed-mobile convergence is poised to extend the advantages of unified communications to mobile workers. With FMC, users can be reached via their IP PBX extensions on their VoIP phones and their mobile devices. Users can place calls through the PBX over a cellular or Wi-Fi connection. By placing calls through the PBX, IT gets better auditing control and cost savings. Some FMC products even let users access unified communications features like IM and presence from mobile devices.
PERILS AND PITFALLS
Involvement from these teams won't end with deployment, either. The variety of integration points mean lines of communication must stay open to quickly diagnose and resolve issues as they occur.
An important point: Be cognizant of E-911 for nomadic workers to ensure that as they change locations they're routed to the right emergency services departments.
