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.

These articles give a great background into VoIP, help you understand all the basics, and answer most people questions. The VoIP/Speed test tool performs a test of your Internet connection and provides a great indication of how well VoIP will work at your home. We highly recommend running this test.


An important disadvantage of the landline is that you cannot easily scale it up or down. This is why many companies with rapidly expanding or contracting business sizes prefer VoIP because it allows enterprise management to easily add, edit or even delete user rights centrally through the control panel. It is not necessary to follow the tedious processes involved if you are using a regular landline. This makes internet phone technology significantly more suitable for large business organizations.
Using a separate virtual circuit identifier (VCI) for audio over IP has the potential to reduce latency on shared connections. ATM's potential for latency reduction is greatest on slow links, because worst-case latency decreases with increasing link speed. A full-size (1500 byte) Ethernet frame takes 94 ms to transmit at 128 kbit/s but only 8 ms at 1.5 Mbit/s. If this is the bottleneck link, this latency is probably small enough to ensure good VoIP performance without MTU reductions or multiple ATM VCs. The latest generations of DSL, VDSL and VDSL2, carry Ethernet without intermediate ATM/AAL5 layers, and they generally support IEEE 802.1p priority tagging so that VoIP can be queued ahead of less time-critical traffic.[16]
Now that so many people are working from home, keeping your business' voice communications organized and centralized can be tricky. Fortunately, that's where cloud-served voice over IP (VoIP) providers can shine. With cloud VoIP (sometimes called a cloud PBX system), you can move direct extensions to new geographical locations simply by clicking a mouse. Devices can also change with similar ease either with a software download or simply by re-configuring call forwarding. With many of these systems also adding a wide variety of team collaboration features, cloud VoIP is probably the best COVID-19 investment a business can make.

An IP phone or VoIP Adapter (ATA) – You’ll see a wide range of prices between the different providers when it comes to equipment. Some providers have expensive equipment and “freemium” service; others will lease you equipment for free and charge more per month. Between those two, you have a lot of in-between. An IP phone plugs directly into your modem or router, and an ATA lets you use a legacy phone over the VoIP network. You need an IP phone to truly enjoy all the benefits of VoIP calling, which is why VoIP phones are becoming more popular.


Cable companies and Internet providers will also provide a bridge device where your phones stay the same and the VoIPing simply happens on the back-end. Just remember that these devices dictate what kinds of features the provider can offer you, so be sure you know what these devices are capable of since there'll likely be more than one model to choose from.

Business VoIP is the modern form of business phone service utilizing an internet connection instead of a PSTN landline connection. By sending your voice, video, and data communications through your internet network, your business can achieve a high quality VoIP phone system for a fraction of traditional legacy setups. Business VoIP solutions differ from landline services as feature rich alternatives for small to medium sized businesses.

A telephone connected to a land line has a direct relationship between a telephone number and a physical location, which is maintained by the telephone company and available to emergency responders via the national emergency response service centers in form of emergency subscriber lists. When an emergency call is received by a center the location is automatically determined from its databases and displayed on the operator console.
Another area of business VoIP support covers the growing number of mobile employees using softphones for sending and receiving calls from a laptop or mobile device. With a cloud-based PBX solution, you can have employees at different physical locations, including multiple time zones. This makes it easier to support longer business hours to cover your entire customer base. Most of the business offerings offer call routing based on the time of day and time zone.
Collective communication is the future of business communication. This type of communication technology enables users to communicate using a variety of data formats. For example, you could text your colleague about something you might have received in an email. Different data formats are combined to ensure that people who are contacted in a way are able to get the message in different ways. VoIP and unified communications go hand in hand.
Voice over Internet Protocol (VoIP), also called IP telephony, is a method and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. The terms Internet telephony, broadband telephony, and broadband phone service specifically refer to the provisioning of communications services (voice, fax, SMS, voice-messaging) over the public Internet, rather than via the public switched telephone network (PSTN), also known as plain old telephone service (POTS).
By default, network routers handle traffic on a first-come, first-served basis. Fixed delays cannot be controlled as they are caused by the physical distance the packets travel. They are especially problematic when satellite circuits are involved because of the long distance to a geostationary satellite and back; delays of 400–600 ms are typical. Latency can be minimized by marking voice packets as being delay-sensitive with QoS methods such as DiffServ.[16]
First, there might be a very low cost or even free "basic" or "introductory" tier that's just so feature poor that the vast majority of customers will opt for the next level up, which will be the full-priced tier. Another common practice is a one- or two-year contract, each with a slightly lower price that are offered next to a significantly higher-priced month-to-month tier. Additionally, while most residential VoIP services offer unlimited calling, some vary their pricing on call restrictions. Those will come either in the form of minutes (with higher pricing attached to monthly overages) or geographic region. The latter usually start with nationwide calling and then tack on another charge for worldwide calling or even separate charges for different countries.
Overall, VoIP is simply the better option for the vast majority of customers. Dropping your landline means no more hidden fees or metered long distance calling charges. Everything is charged at one low rate by most providers and your ability to customize your phone service to exactly what you need is far greater. Unless you've got some highly unique circumstances that somehow mandate a landline, VoIP is simply the better choice.

Government and military organizations use various security measures to protect VoIP traffic, such as voice over secure IP (VoSIP), secure voice over IP (SVoIP), and secure voice over secure IP (SVoSIP).[39] The distinction lies in whether encryption is applied in the telephone endpoint or in the network.[40] Secure voice over secure IP may be implemented by encrypting the media with protocols such as SRTP and ZRTP. Secure voice over IP uses Type 1 encryption on a classified network, such as SIPRNet.[41][42][43][44] Public Secure VoIP is also available with free GNU software and in many popular commercial VoIP programs via libraries, such as ZRTP.[45]

GoToConnect has established a positive industry reputation since its launch as Jive in 2006, thanks mostly to its interface simplicity, focus on small businesses, and large array of telephone features that are available to all pricing tiers.

The technical details of many VoIP protocols create challenges in routing VoIP traffic through firewalls and network address translators, used to interconnect to transit networks or the Internet. Private session border controllers are often employed to enable VoIP calls to and from protected networks. Other methods to traverse NAT devices involve assistive protocols such as STUN and Interactive Connectivity Establishment (ICE).


Residential VoIP reviews submitted by real users can be a great tool when trying to decide which provider is the best choice for you. Each review includes ratings for various aspects of the service, such as sound quality, features, customer service and more, as well as their personal comments based on their experience of the service. Reading reviews is an essential part of the decision making process.
