The Case for Enterprise VoIP
By Brian Solomon, TMCnet Web Editor
Some four or five years ago, VoIP

became a very viable alternative for business use, thanks to two factors. The first was the growth of Ethernet. By 2003, most businesses were already wired with 100Mbps Ethernet infrastructure, making it the standard way networking is delivered.
Second, vendors improved VoIP products to the point where the voice quality became as good as the older circuit-switched technology used on the PSTN

. The pops, burbles, and latency disappeared, and nowadays it’s nearly impossible for a caller to tell the difference between a VoIP call and one using PSTN.
Adding to VoIP’s attractiveness has been the development of PBXs that are fully featured and inexpensive. PBX

can now be just an application that runs on a standard platform, which means companies no longer have to pay the costs once associated with buying a phone system.
VoIP offers enterprises tremendous savings in long distance charges. Whether it’s interconnecting branch offices or routing calls to a remote call center, VoIP is the best solution. However, security over the public Internet is always a concern.
For this reason, business adopting VoIP also need a complete solution for an enterprise wide, secure VoIP Virtual Private Network (VPN

). The associated security features ensure no unauthorized VoIP callers can access the enterprise VoIP network. Easy to use routing features enable flexible blocking of unauthorized calls by internal users. Secure collection of all call detail records provides a complete audit trail for monitoring calls by internal users.
