The quality of your connection can potentially impact the clarity of your calls, so pay close attention. 
While we think Grasshopper is great for small businesses, it misses out on our “Best Small-Business Phone Service” title because, compared to Ooma, Grasshopper is a little expensive. Grasshopper plans start at $26 per month, assuming you sign up for annual billing. And starting plans include only one business phone number with up to three extensions.
On the higher end of this space, hosted PBX providers, such as RingCentral Office, will generally offer (sometimes even require) on-premises handset hardware, like desk or cordless VoIP phones that get sent to you pre-configured to work with their service. Plug the phones in, make sure they see an internet connection, and after some self-configuration time, your VoIP service goes live auto-magically.

SIP networks usually have a proxy server and a SIP gateway. The proxy sever helps lighten the functional requirements of SIP endpoints. It also acts as both client and server, but it adds functionality around call routing and policy-based management. SIP gateways handle the routing and connectivity requirements for connecting SIP calls to other networks. Typically, the advanced features of the VoIP vendors we review here are largely based on the proprietary management technology they build into their proxy servers and gateways. By offering VoIP solutions where these elements of a SIP solution are hosted in the cloud, the providers reviewed here have more flexibility in building advanced features since they have more control over deployment and reliability.


Whether it's a dedicated bridge device or a special VoIP phone, you'll need something on the hardware side compatible with VoIP in order to access the technology's chief benefit: its software layer. It's at this layer where VoIP's advanced communication and collaboration features are enabled and how well the provider has leveraged those advantages will be directly reflected in how its proprietary hardware and back-end services are programmed. Whether it's a phone or a bridge, if you're worried about getting lost in technobabble when trying to setup your new phone service, remember that the best providers should be able to ship you pre-configured devices that shouldn't require much, if any, intervention on your part. With these, you simply plug them into your router or connect them to your Wi-Fi network and they'll go out and find the provider's network on their own. Just power them up, connect to your network, and wait for the light to turn green.
