VoIP technology primer for SMBs
There are four basic models of VoIP to choose from
Hosted: SMBs access the call processing server, also known as Internet Protocol private branch exchange (IP PBX), through a Web-based interface. The hosted PBX is off site, is managed by a service provider and offers the same functions as a PBX, for a contracted fee, without the sizable upfront costs of buying, installing and maintaining the equipment on premises. The downside is the SMB gives up control.
Managed: The IP PBX resides at the company but is managed remotely by a service provider, again avoiding upfront capital investment and maintenance costs. But the on-site IP PBX is subject to power outages or natural disasters.
Do-it-yourself: The SMB takes complete control, buying the VoIP system itself, or through resellers, and managing the system. Cost and no disaster recovery backup are the potential drawbacks.
Broadband VoIP: SMB takes the consumer approach, using an analog telephone adapter to access VoIP through a broadband Internet connection. A small business could reap significant savings. The big worry? Call quality and quality of service.
Who should ring in VoIP? SMBs with branch or satellite offices stand the best chance of realizing cost savings by reducing the cost of moving, adding, changing or removing phone lines for employees and long-distance charges between offices and to clients. SMBs with a mobile salesforce or a large number of teleworkers are good candidates for VoIP.
