With Voice over internet protocol becoming the preferred method of transmitting streaming conversations during a phone call, it is essential that a network be properly configured for optimum audio quality. Prioritizing voice traffic on a network is critical to quality audio during phone calls. The network will simply try to resend data during times of network congestion when transferring or sending data. Data is usually very forgiving and will pick up where it left off when the bottleneck clears. In the case of a voice conversation, this particular strategy results in garbled conversation because of latency, delay, and jitter. The voice data packets must be reassembled on the receiving end in the order in which they were transmitted. Since data is sent over multiple channels by choosing the best route based on current network traffic, it is essential that the data packets be reassembled on the receiving end in a specific order and that they are not subject to the time delays seen during times of heavy network congestion. This is accomplished through network prioritization. All voice traffic is given priority on the network through the use of QOS. This configuration acts in much the same way as a police officer directing traffic in a busy city. When the amount of data comes close to or exceeds the available bandwidth on a network, QOS will stop all data traffic while allowing voice traffic to continue on. In this way, you’re telling your network data packets that are designated as voice packets are always given priority for routing. Before introducing Voice over internet protocol technology into your network, it is essential that a network assessment be completed prior to implementation. Depending on the expected call volume and the current level of utilization on the network, it might be necessary to add additional bandwidth to accommodate voice traffic. Depending on the average number of calls per day, you could see a significant demand on network bandwidth. If the amount of bandwidth is inadequate, voice quality will suffer with garbled audio and poor performance. Although inadequate bandwidth is a common problem with Voice over internet protocol audio quality, there are other factors in the network that can affect the quality of a Voice over internet protocol call. Some networks simply have too many hops or transfers from router to router. Each of these hops can create delay because each router has to read the packet to determine its destination and then route to the next point in the route. Obviously, the greater the number of times that this occurs the greater the delay the packet will experience before reaching its destination. Whenever possible, Voice over internet protocol traffic should be routed in as direct a line as possible with a minimal number of hops. This can be accomplished by designating a VLAN or virtual local area network exclusively for Voice over internet protocol traffic. The VLAN can be configured to route voice data in a more direct line than the rest of the data being…

VOIP – What It Does and What the Benefits Are

VOIP, or Voice over Internet Protocol, is a type of phone service that allows you to make calls over the internet. You do not have to have a local phone service at all, and VOIP is often more cost-effective because it has a number of features that traditional phone services do not offer, and in many cases, it is actually cheaper than other phone services. The Equipment Needed for VOIP To make VOIP calls, you first have to have an internet connection. You do not actually require a computer to make these calls, but you do need either an IP phone or an analog telephone adapter, or ATA. This adaptor has two connections on it. One plugs into your standard phone, while the other plugs into one of the Ethernet connections on the back of a standard router. Then you connect to the internet and go through your selected VOIP solution provider to actually make phone calls. The other option is to purchase an IP phone. These phones essentially have their own IP address just like any other device on a computer network (computer, smart phone, wireless gaming device, etc.). However, instead of plugging the phone into a standard telephone jack, it has an Ethernet connection and is plugged directly into your router. Then you go online, connect to your selectedVOIP service provider, and make your calls. The Lower Cost of VOIP Many home VOIP services cost less than $10 a month. Of course, there is the cost for equipment, but that’s a one-time cost. You also have to always have an internet connection, but many people pay for that anyway. The reason why the cost is so low is that transmitting calls over the internet cost nothing. Even international calls do not cost any extra. The reason VOIP companies do charge a monthly fee is so they can maintain their servers and the other equipment that actually handles your call. In some cases, the VOIP service actually includes its own internet connection that, while you cannot use for data, handles all of your voice calls. Extra Features There are many great features provided with a VOIP solution provider that you do not get with traditional services. Many IP phones allow you to send and receive text messages, set up a three-way call, block calls, and transfer your existing phone number to your new VOIP service. With IP phones, your phone number is actually attached to the phone itself, not your physical location. This means you can take your IP phone with you to any location that has an Ethernet jack and internet connection. Just plug in your phone and you will receive all of your calls just as if you were at home. This is great for businesses since it means employees can work from home or, while traveling, receive calls as if they were in the office. There’s no call forwarding to set up. In fact, there are some VOIP packages specifically aimed at businesses and offer faxing,…

Nergy Telecom maintains termination agreements with many major carriers among which are Verizon Business (ex MCI) Standard and Premium routes, TATA Communications (Prime Route Plan), WaveCrest (CLI and Silver routes), Arbinet, CCS and AT&T networks. Due to our long-term partnership and large purchasing volumes Nergy Telecom obtains the best terms and conditions from the above mentioned carriers. Considering that it is quite difficult for new or existing operators to get direct access to world’s largest carriers, Nergy Telecom offers to operators a possibility to terminate calls to such carriers through Nergy Telecom’s platform. This offer is only available to businesses or individuals that already have their own VoIP equipment and use their own IVR, billing and retail account management systems.   Here is an overview of all the features and advantages available to operators:   Features and Advantages Access to Verizon Business (ex MCI) Premium and Standard routes, TATA Communications (Prime Route Plan), WaveCrest (CLI and Silver routes), Arbinet, CCS and AT&T networks. No need to make the large deposits or prepayments that you would have to make when getting connected to major carriers. Therefore you will be able to invest the money into your core business and use it much more effectively. No need to go through the lengthy process of signing agreements and dealing with other paperwork (with major carriers this can take up to 2-3 months). All you need to do is to send us an application and make an initial prepayment (minimum 1000 USD). LCR (Least Cost Routing) management. Accessing the web interface operators can specify carrier priority for each destination and also the number of attempts to be made for each carrier when the call does not go through. For example, you can set the following routing plan for destination Angola: Arbinet- priority #1, 3 attempts, WaveCrest (CLI route)- priority #2, 3 attempts, CCS – priority #3, 4 attempts. This will mean that when you send a call to Angola, our platform will try first to terminate it through Arbinet, it will make 3 attempts if the call cannot connect, then it will try to terminate the call through WaveCrest(CLI route) etc.). This will provide the flexibility for operators to choose the best quality at the lowest rates. Access to the web based Operator Account Management interface with the following features: Current account balance information Viewing the wholesale rates Viewing the list of zones with prefixes that are currently configured at Nergy Telecom’s platform Routing Management Traffic and Error reports Operator Profile Management In order to access a demo account please go to and use these details to log in (login – DEM, password – dem1006).
