Flexible Messaging Options – There are a number of business phone service options available that make retrieving and maintaining your business messages very simple. With Voicemail Transcription, you can read the message in your inbox, or receive it as a text instead of listening to it. Let’s say a client calls you about a fax he needs, and leaves a fax number on the message. With a few clicks you can virtually send the fax as a PDF to that number.

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.


Though many consumer VoIP solutions do not support encryption of the signaling path or the media, securing a VoIP phone is conceptually easier to implement than on traditional telephone circuits. A result of the lack of encryption is that it is relatively easy to eavesdrop on VoIP calls when access to the data network is possible.[38] Free open-source solutions, such as Wireshark, facilitate capturing VoIP conversations.
SIP-T29G IP Phone is the most advanced model in the Yealink T2 series. It has a high-resolution TFT color display, delivers a rich visual experience.Yealink Optima HD technology enables rich, clear, life-like voice communications. Supports Gigabit Ethernet, a variety of device connections, including EHS headset and USB. With programmable keys, the IP Phone supports vast productivity enhancing features.
A voice call originating in the VoIP environment also faces challenges to reach its destination if the number is routed to a mobile phone number on a traditional mobile carrier. VoIP has been identified in the past as a Least Cost Routing (LCR) system, which is based on checking the destination of each telephone call as it is made, and then sending the call via the network that will cost the customer the least. This rating is subject to some debate given the complexity of call routing created by number portability. With GSM number portability now in place, LCR providers can no longer rely on using the network root prefix to determine how to route a call. Instead, they must now determine the actual network of every number before routing the call.[citation needed]
However, for many businesses there's a need to route calls to the PSTN and other analog phones that might remain in use, too. This may mean a PSTN gateway, or even a hybrid PBX, where there's at least a small telephone switch located on-site. Note that these days, a PBX looks exactly like the other servers in your data center, except with an attached means of handling local and analog phones. Many small businesses, however, are avoiding on-premises PBXes partially due to cost savings and partially because the capabilities offered by all-cloud systems are more than advanced enough for their needs. Some virtual cloud PBXes can handle PSTN connectivity without on-site hardware requirements.

Network routers on high volume traffic links may introduce latency that exceeds permissible thresholds for VoIP. Excessive load on a link can cause congestion and associated queueing delays and packet loss. This signals a transport protocol like TCP to reduce its transmission rate to alleviate the congestion. But VoIP usually uses UDP not TCP because recovering from congestion through retransmission usually entails too much latency.[16] So QoS mechanisms can avoid the undesirable loss of VoIP packets by immediately transmitting them ahead of any queued bulk traffic on the same link, even when the link is congested by bulk traffic.
Not every internet connection is VoIP ready, so before you sign up, make sure that your line will provide you with the level of VoIP speed and service you need. You can easily find resources online for checking the speed and call quality of your connection. The quality of your connection can potentially impact the clarity of your calls, so pay close attention. 
Typically, price is one of the most important reasons people opt for residential VoIP. One of the most attractive is the "triple play" sales pitch we mentioned above made by almost every regional residential cable company and internet provider: Get your Internet, TV, and phone service all rolled into one monthly charge. Not only is that usually an attractive number, it also means a technician will hook everything up for you including your phone, and you'll probably be able to use the same phone you're using now instead of having to migrate to a VoIP phone.
Because of the bandwidth efficiency and low costs that VoIP technology can provide, businesses are migrating from traditional copper-wire telephone systems to VoIP systems to reduce their monthly phone costs. In 2008, 80% of all new Private branch exchange (PBX) lines installed internationally were VoIP.[9] For example, in the United States, the Social Security Administration is converting its field offices of 63,000 workers from traditional phone installations to a VoIP infrastructure carried over its existing data network.[10][11]

VoIP (pronounced “Voyp”) stands for “Voice over Internet Protocol” and to make a long story short—it allows you to make calls through your home internet connection. When you make a call with your VoIP system, your voice is converted into data and transmitted to the caller at the other end in the form of high-quality audio. The sound and connection typically are seamless enough to where you won’t even know the call you’ve received is from a VoIP line.

On the customer service front, RingCentral receives mostly positive reviews, offering phone assistance during standard work hours, 24/7 online chat service, and ticket service, in addition to weekly webinars and an extensive online knowledge base. Businesses of 20 users or fewer should note, however, that RingCentral favors larger enterprises for US-based support and outsources smaller-office support overseas.
The early developments of packet network designs by Paul Baran and other researchers were motivated by a desire for a higher degree of circuit redundancy and network availability in the face of infrastructure failures than was possible in the circuit-switched networks in telecommunications of the mid-twentieth century. Danny Cohen first demonstrated a form of packet voice in 1973 as part of a flight simulator application, which operated across the early ARPANET.[69][70]
