VoIP sounds almost magical: The hype makes it sound more flexible, more full-featured, and best of all, significantly cheaper than placing your calls through traditional telephone service providers.
But is VoIP really all it's cracked up to be? Are the potential pitfalls worth the potential monetary payoffs? I'll walk you through the basics, discuss the pros and cons, and take a look at three commercial VoIP services of varying complexity.Small Business VoIP
How Does VoIP Work?
Generally, things are pretty simple if you're looking for a hosted service. Many of the top VoIP providers handle all the heavy lifting offsite, delivering calls to your phones and software clients without much hassle, especially if you use phones that are plug-and-play certified for the service in question. The majority require no additional on-site hardware aside from those phones; at most, you might need to find a space for a small box of hardware somewhere on-site.
In contrast, maintaining a self-hosted, on-site VoIP system requires a bit more work. You need an IP-based private branch exchange—a VoIP-friendly version of the PBX phone systems that many offices use—to route your calls to the appropriate phones on your network, as well as a device called a PSTN gateway. The PSTN gateway sits between the IP-PBX software and the analog signals of the public switched telephone network, converting calls to and from digital signals as necessary.
No matter which option you choose, typically you can handle the basic settings for your phone lines or extensions over the phone, while tweaking more advanced options requires diving into your provider's online account interface.
What Do You Need to Implement VoIP?
Depending on the size of your company and the infrastructure you already have in place, jumping on the VoIP bandwagon could cost your company next to nothing, or it could entail significant up-front costs.
Make sure that your internal network—including your routers and switches—can handle the load, too. Most providers suggest using a router with configurable Quality of Service settings and assigning VoIP traffic high priority to maximize quality.business voip solutions
If your Internet service provider has a bandwidth cap in place, you should take that into consideration as well. Most VoIP service providers use the high-quality G.711 codec for VoIP communications, which consumes 64kb of data every second you talk. In reality, even a large number of people should be able to chat it up on VoIP without having to worry about hitting bandwidth caps, but you'll want to keep close tabs on your data usage to avoid exceeding that cap.business voip solutions
