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.
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.
Sending faxes over VoIP networks is sometimes referred to as Fax over IP (FoIP). Transmission of fax documents was problematic in early VoIP implementations, as most voice digitization and compression codecs are optimized for the representation of the human voice and the proper timing of the modem signals cannot be guaranteed in a packet-based, connection-less network. A standards-based solution for reliably delivering fax-over-IP is the T.38 protocol.
Some of that software is running on the provider's servers, but parts of it will be running on your devices, whether that's a PC a mobile phone or a VoIP phone. It's this software layer that provides the rich feature fabric, which along with its lower price, is what's drawing residential customers to the technology. Some of the more popular advanced features you'll find available in a residential service, include:
As always the best place to start is at the beginning! The following buttons provide access to some of our best guides and tools for getting started with VoIP. 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.
A key attraction of VoIP is that it gives these systems the flexibility to work in a wide variety of environments ranging from analog desk phones to softphones piggy-backing on a cell phone. These systems can often also integrate all or part of their softphone clients into other back-office applications, like your customer relationship management (CRM) or help desk platforms. Simply picture the standard interface of such an app that suddenly sports a dial pad and some function buttons as a pop-up screen and you'll have a very basic idea of how some of this works. In addition, these cloud based systems can have a variety of phone numbers in global locations, so that your customers can have free access to your phone at little or no charge.  
GoToConnect has nearly as many glowing critical reviews as the Radiohead discography, minus the pretentious lyricism. 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.

Your IT staff will understand the basics of what needs to be done before a VoIP system can be selected and installed. That will include capacity testing on your current pipes and a thorough audit of your organization's network management capabilities to make sure they can support and secure the new flow of VoIP data. But for business-level users, selecting a phone system that will help them keep their various processes moving forward, especially the customer-facing ones, starts with understanding what VoIP really is.

The RTCP extended report VoIP metrics block specified by RFC 3611 is generated by an IP phone or gateway during a live call and contains information on packet loss rate, packet discard rate (because of jitter), packet loss/discard burst metrics (burst length/density, gap length/density), network delay, end system delay, signal/noise/echo level, mean opinion scores (MOS) and R factors and configuration information related to the jitter buffer. VoIP metrics reports are exchanged between IP endpoints on an occasional basis during a call, and an end of call message sent via SIP RTCP summary report or one of the other signaling protocol extensions. VoIP metrics reports are intended to support real-time feedback related to QoS problems, the exchange of information between the endpoints for improved call quality calculation and a variety of other applications.
That being said, Grasshopper doesn’t offer any conferencing tools. For that, you’ll have to sign up for join.me—Grasshopper’s sister company. This service offers both video and audioconferencing, but it does cost an extra $10–$30 per month. That’s another strike against Grasshopper, since most providers in Grasshopper’s price range include conferencing features.
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.
Yealink DECT repeater RT20U, designed in accordance with Digital Enhanced Cordless Telecommunication (DECT) standard, is widely compatible, easy to install, and a user-friendly display concept. The repeater, base station, and cordless handset employ wireless connection. It can be deployed to extend the DECT radio coverage of all Yealink base stations significantly in all directions. Signals with clear status LED display are exchanged without acoustical, and visual differences.
The security concerns of VoIP telephone systems are similar to those of other Internet-connected devices. This means that hackers with knowledge of VoIP vulnerabilities can perform denial-of-service attacks, harvest customer data, record conversations, and compromise voicemail messages. Compromised VoIP user account or session credentials may enable an attacker to incur substantial charges from third-party services, such as long-distance or international calling.

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]
The receiver must resequence IP packets that arrive out of order and recover gracefully when packets arrive too late or not at all. Packet delay variation results from changes in queuing delay along a given network path due to competition from other users for the same transmission links. VoIP receivers accommodate this variation by storing incoming packets briefly in a playout buffer, deliberately increasing latency to improve the chance that each packet will be on hand when it is time for the voice engine to play it. The added delay is thus a compromise between excessive latency and excessive dropout, i.e. momentary audio interruptions.
A business phone system helps you to present a professional image to your customers. If you do not have a need for office phones or spend the money, you can still use a virtual phone system to project a professional look. This enables you to place a call directly to a mobile phone. It also has key features like voicemail transcription and automated attendants.
