The only additional piece of equipment that you need is an Analog Telephone Adapter (also referred to as an ATA) that allows you to connect your existing telephone to your home Internet. This equipment is typically provided on a free lease basis from the home VoIP provider that you choose, or you can use you own device if you prefer. You can also use IP phone(s) instead of using the ATA with your existing analog phones. The sound quality is better but there is more up front cost as IP phones are more expensive than the ATA devices.

In the United Arab Emirates (UAE), it is illegal to provide or use unauthorized VoIP services, to the extent that web sites of unlicensed VoIP providers have been blocked. However, some VoIPs such as Skype were allowed.[56] In January 2018, internet service providers in UAE blocked all VoIP apps, including Skype, but permitting only 2 "government-approved" VoIP apps (C’ME and BOTIM) for a fixed rate of Dh52.50 a month for use on mobile devices, and Dh105 a month to use over a computer connected."[57][58] In opposition, a petition on Change.org garnered over 5000 signatures, in response to which the website was blocked in UAE.[59]


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.
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.

The quality of voice transmission is characterized by several metrics that may be monitored by network elements and by the user agent hardware or software. Such metrics include network packet loss, packet jitter, packet latency (delay), post-dial delay, and echo. The metrics are determined by VoIP performance testing and monitoring.[20][21][22][23][24][25]

We recognize that not all our readers’ businesses are based in the US. So we took another pass at our content to provide more information on each provider’s international offerings. And because 8x8’s international rates on calls made from the US are so good, we bumped it up to our number five spot. Finally, we added info about Ooma’s new plan (Ooma Office Pro) to the offerings mentioned below.
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.
These include features like voicemail-to-email (and/or fax to email) which will automatically take your voicemail messages and send them as audio files to your email, making you much less likely to miss important messages. Many companies can also provide you with voicemail transcription to text, which will automatically convert the messages to text in an email, saving you even more time. 
Another legal issue that the US Congress is debating concerns changes to the Foreign Intelligence Surveillance Act. The issue in question is calls between Americans and foreigners. The National Security Agency (NSA) is not authorized to tap Americans' conversations without a warrant—but the Internet, and specifically VoIP does not draw as clear a line to the location of a caller or a call's recipient as the traditional phone system does. As VoIP's low cost and flexibility convinces more and more organizations to adopt the technology, the surveillance for law enforcement agencies becomes more difficult. VoIP technology has also increased Federal security concerns because VoIP and similar technologies have made it more difficult for the government to determine where a target is physically located when communications are being intercepted, and that creates a whole set of new legal challenges.[68]

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.
Voicemail routing can take multiple forms, but they're basically rules you can apply to incoming calls that will automatically route them to voicemail without even causing a ring. For example, if calls come in with Caller ID blocked, those can be routed directly to voicemail. Or if you're simply not into talking to anyone, you can hang out a digital Do Not Disturb sign and route all calls to voicemail, perhaps until you're feeling more social or every day between the hours of 9 PM and 7 AM.
