  • 05/21/15--01:51: Cloud PBX
  • A cloud PBX system is a based on cloud computing technology, where data is stored and transferred over the Internet, rather than on a computer or piece of hardware that an end-user owns.

    Cloud technology that has been around for many years, but has only more recently become popular for consumer use with the introduction of programs like MobileMe and the iCloud, both consumer-based cloud computing technologies.

    History of the Cloud

    Cloud technology has many applications for businesses and consumers. In the mid-1990’s, companies that had previously used “point-to-point” data circuits to move and store data began to use a cloud technology instead as they found that this was a cheaper way to do the same tasks, and made more efficient use of bandwidth.

    The term “cloud” likely refers to the drawings of clouds used by its program developers to represent the abstraction of the Internet. The symbol was used to mark the division between responsibilities of the service provider company and the responsibilities of the customer.

    Cloud technology means that you can access the data and services of your cloud from any device connected to the Internet. So, with a cloud PBX provider, you can use all of the standard PBX features without the need of an actual PBX in your home or office.

    What is PBX? What is Cloud PBX?

    PBX, or public branch exchange, is the name used to refer to the technology that any given telephone provider uses to route calls. Originally, a PBX was a large unit of hardware that had to be stored on site and operated by hand. These machines could be very costly for a company, as they were large, needed special storage facilities, needed regular repairs, and had to be operated manually.

    Companies with multiple phones and many employees can’t function properly without some kind of PBX technology in the office. In more recent years, a PBX could be made to operate automatically, without an operator, but even these devices were expensive and complicated (the cheapest are around $400). And if a business needed to move to a new location, or add or remove a phone line, the process could be very costly and time consuming.

    Initial cost and upkeep of traditional PBX vs cloud PBX

    • Traditional PBX: About $5,000 including cost of installation and new equipment fees. $10.00/hour for an operator. If managed without an operator, can still run to around $300 or $400 for upkeep and Internet connection.
    • RingCentral Virtual PBX: $19.99/month plus $0.049/additional minute
    • Cebod Telecom: $19.99/month All Inclusive and Unlimited Call
    • Vocalocity Virtual Extension:$14.99/month plus $0.03/additional minute
    • RingOffice Cloud Phone System: Plans from $10/month
    • Switchvox Cloud by Digium: $29/month, unlimited minutes and all UC features included
    • MultiTEL Cloud Hosted PBX— free for up to 5 users, $0.0095 for calls to US/Canada
    • VoIPstudio : A Simple and Powerful Cloud Based Business PBX System. Plans start from $ 4.99/Month

    Cloud PBX gives you access to PBX capabilities without the need for complicated and expensive equipment. Cloud PBX is a kind of hosted PBX or virtual PBX, meaning that all of the routing services are performed by your VoIP provider, rather than by an employee managing a PBX system in your office.

    How does it work?

    All cloud technologies are dependent on the Internet. A cloud PBX works by connecting to your IP, or Internet phone, for its internet connection. So, you must have a VoIP or other IP system in place in your office in order to use a cloud PBX. ...

  • 05/21/15--12:05: VoIP Termination
  • Please add information to this page about VoIP call termination.

    What is VoIP Termination?

    VoIP call termination is used to refer to the procedures that are used for routing telephone calls from one provider to the next provider until the call has been routed to the last telephone company and has been received by the recipient. Voice termination is another term that is used for call termination. The telephone companies are also referred to as providers or carriers.

    Called Party

    The called party is the person who has received the telephone call. The end point of the route may be on the Internet or may be at a point that was reached by routing the call through the public switched telephone network. The procedures for routing the call stop when the call has been received by the recipient. The process may seem simple to individuals who do not experience problems with making telephone calls but is not so simple to individuals who make calls that will not connect such as calls to a different country.

    Calling Party

    The calling party is the person who has initiated the call and who wants to be connected to the called party. There may be problems with the telephone calls that begin on the Internet and end at a cellular phone. The sound of the voices may seem to be amplified with echoes and have a scratchy quality. The calls that are initiated with Google Voice may never connect or could be delayed.

    VoIP

    Voice over Internet protocol (VoIP) is a term that is used to describe a call that was initiated on the Internet such as Skype calls or calls made with Google Voice. The calls that were initiated on the Internet usually end at a point that is not on the Internet. Most of the recipients of telephone calls receive the calls with a landline phone or with a cellular phone. The route may begin on the Internet but will end at a point that was reached by routing the call from the public switched telephone network (PSTN), which is the common description for call termination.

    Internet Networks

    A tier-one operator is licensed and registered to operate an Internet protocol (IP) network for Internet telephony services. Tier-one operators can handle call origination and call termination. A tier-two operator can lease services from a tier-one operator. The tier-three operators can lease services from either a tier-one or two-two operator. There are also resellers of VoIP services and wholesalers in the market. The quality of the services is not very high because of the inconsistencies in the market such as fluctuations with demand, fraud and problems with doing business on an international level.

    Call Origination

    Call origination is used to refer to telephone calls that originate from the public switched telephone network and end the route on the Internet. Call termination is considered to be the opposite of call origination because the direction of the paths are reversed. The terms are associated with the starting point of the calls, path of the route of the calls and termination point of the calls. The operators of IP telephony services can handle calls that originate or terminate on the Internet.

    Fees

    The fees for services are subject to the regulations of several countries because the routes of the calls will cross over more than one country. Those countries can use legislation to control the fees for the services. Termination rates are usually very high for the countries in the Middle East and Asia. The rates are intentional high because there are more incoming calls than outgoing calls from the countries, which is caused by the diaspora effect of a migrating population.

  • 05/21/15--22:48: VoIP Wholesale
  • Wholesale VoIP Market:


    There is no doubt today that VoIP is taking over the telecom market, and every month increases penetration into services and industries. Competitive carriers are looking at the numerous ways to make money from this exploding technology, but there's a lingering question as to whether it is profitable to deliver VoIP in a wholesale model? Their customers, typically Service Providers, are looking for their ‘competitive advantage' into this ‘lowest price' race, leveraging within three key alternatives for packet telephony : “build” , “buy” or “rent”. Business aspect, there’s no need to invest tens of millions of dollars in wholesale VoIP to join in. Many Telecom Companies have done the work for you. They offer a complete, turnkey VoIP business service and equipment. Now you can start wholesale VoIP business with virtually no investment and yet reap great dividends.

    Wholesale VoIP Resellers:


    In today’s world, Service providers seeking to deliver VoIP to as wide a customer base as possible may find that becoming a wholesale VoIP reseller is the way to go. Wholesale VoIP may be sold to both other service providers and to enterprises or residential customers.

    Reselling IP telephony as a wholesale VoIP company is becoming an increasingly popular business model. For many companies, becoming a wholesale VoIP provider hits the sweet spot between profit and market control. Any firm with a well-established customer base is a good candidate for reselling wholesale VoIP.
    Becoming a wholesale VoIP reseller is not a decision that should be taken lightly. It does, however, offer the potential of being very lucrative if done right.

    Wholesale Consumer Demand:


    An important characteristic of the industry is the complex segmentation of consumer demand and rapid change in the characteristics that are being demanded, both at the end customer and in the intermediate ones (wholesale customers).
    Demand coming from ‘packed customers'? will be significantly different of the conventional telecommunications one, were telephony was the unique service to provide and differentiation was based on tariff-distance paradigm, being today's service offerings closer to data applications rather than telephony. Voice communication (and not old POT telephony) becomes the common feature into several communications applications and devices, but not the unique one.
    Messaging, conference, collaboration, web contact centres, etc … requires a common communication format between parties, which is voice, implemented through VoIP technologies. Heterogeneous and rapidly changing customer demands and products are important dynamic influences on the evolving structure of the telecom industry, resulting into a new value-chain.
    Telecommunication markets evolution will be driven by ‘packed customers' demand rather than networks, technology or finance, changing many decades rules into this industry.

    Finance in Telecommunication Industry:

    Finance institutions had been influencing Telecomm Industry since the beginning, due the business itself was characterized by huge investments, big market shares and bigger capitalization, influencing in many cases top management, who addressed their strategy towards ‘stock' opportunities rather long term and solid business models. WorldCom crash has been an example of this ‘financial market' pressure and wrong business management.
    Today, the networks has been deployed. New scenario in Telecoms enable new players to deploy services over broadband without proprietary network and this new generation business will not be anymore capital intensive, let's say these will be innovation intensive.

    U.S. VoIP Market:

    The US market for VoIP advanced dramatically in 2006-2007, adding 3.8 million VoIP households in 2006, reports In-Stat: As a result, wholesale VoIP revenues grows quickly, as MSOs, Skype, and a myriad of new entrants most lacking network facilities enter the market and drive demand for telephony features and applications, the high-tech market research firm says.
    As retail VoIP expands, wholesale VoIP will accelerate quickly, says Bryan Van Dussen, In-Stat analyst. The largest segment remains international VoIP, but we expect the market for local services to surge from 12% of all revenues to 27% by 2010.
    Recent research by In-Stat found the following:

    • Consumer VoIP adoption will drive wholesale VoIP revenues to $3.8 billion by 2010 from $1.1 billion in 2006.
    • In-Stat finds small businesses are driving the growth of hosted services in the U.S. Hosted VoIP seats in the U.S. ...

    Business VoIP Providers - Compare and Choose a Business VoIP Provider


    Quality business VoIP providers today offer a wide variety of feature packages, services and prices. Selecting the ideal provider and service options will depend on your type and size of business, features needed and projected volume of usage. Even when working with top-tier providers, your basic monthly service charges per line may begin at rates as low as $20. Before choosing your VoIP provider, it is essential to first determine your company's precise telecommunications needs to enable timely and cost-efficient initiation of your service. By consulting your chosen Voice over IP service team and seeking their expert advice in advance, you can be prepared to take the following steps to facilitate the smooth, productive startup of your services:

    • Evaluate Your Internet Connection. - Determine the strength and capacity of your Internet connection and bandwidth. You need to ensure that your system has adequate speed to best accommodate your new VoIP installation for top quality service.
    • Assess Your Company Budget and Needs. - With knowledge of your company's current budget and VoIP needs, you can more easily select the service provider and feature options that meet your requirements.
    • Determine Your Equipment Needs. - Evaluate your current and near future VoIP equipment needs. Phones can be purchased from around $50 to $500 or more. Once you decide which feature options are immediate requirements and which ones can be added later as needed, you are ready to choose your service provider.
    • Compare VoIP Providers. - By comparing VoIP company service options, advanced features and equipment along with user and industry reviews, you can best make a wise decision, selecting the ideal VoIP provider for your enterprise.

    Important Information to Request from Any Potential VoIP Provider

    Before signing a service contract with any business VoIP provider, be sure to request basic service information and practices in writing. You need to be certain of such details as startup costs and monthly fees, any limitations and costs on portable phone numbers and exactly which features are included in the service package you select. You also need to know if international calling is included, charges for adding extra features and the extent of customer care and technical services provided. Also important are such issues as whether your provider offers a money back guarantee and if there are any cancellation fees. It is also helpful to determine prior to signing up for VoIP services if there are any hidden fees assessed by your chosen provider.

    Take Full Control and Advantage of Your VoIP System

    Once your new business VoIP system and service are in place, you and your staff members will have full-control capabilities for use of your business communications system. Your service provider will ensure connection with your online portal for customizing your telecomm options. These modern digital portals are user-friendly, enabling feature changes and additions to be made for immediate availability. You and your staff can make decisions and changes in real-time that work for you right in the moment.

    You can manage your call settings remotely, directing calls to voicemail or having them transferred to another number or extension. You can also make exceptions to any chosen setting in your phone system. For example, if you are expecting an important business call and want to take that call, but hold all other calls for a few hours, you can set your phone to direct only the designated call to ring on your extension. This system allows and encourages you to take complete control of your telecommunications systems and settings so that the service works for your best interests and immediate needs at all times.

  • 05/23/15--06:03: NAT and VOIP
  • What is NAT?

    NAT (Network Address Translation) is a technology most commonly used by firewalls and routers to allow multiple devices on a LAN with 'private' IP addresses to share a single public IP address. A private IP address is an address, which can only be addressed from within the LAN, but not from the Internet outside the LAN. In order to let a device with a private IP address communicate with other devices on the Internet, there needs to be a translation between private and public IP addresses at the point where the LAN connects to the Internet, that is within the firewall/router connecting the LAN to the Internet. Such a translation is commonly referred to as NAT (for Network Address Translation) and a router doing such translation is often called a NAT router or NAT firewall/router. Sometimes NAT is also called IP Masquerading. The passing of traffic through NAT is called NAT Traversal.

    The way NAT works is in principle rather simple. When a device on the LAN initiates a connection with a device on the Internet, the device will send all traffic to the NAT router first. The NAT router then replaces the source address, which is the device's private address, with its own public address before passing the traffic to its destination on the Internet. When a response is received, the NAT router searches its translation tables to find the original source address of the packet from which the device on the LAN originally started the connection and thus passes the response to that device.

    Unfortunately, when a connection is originated by a device on the Internet outside the LAN it is not clear which device on the LAN the connection is meant to be established with. In this case there needs to be some rule that tells the NAT router what to do with the incoming traffic, otherwise it will simply discard the traffic and no connection will be established. If the NAT router supports what is commonly referred to as a 'software DMZ' it can handle simple rules, such as "pass all incoming connection requests to the device with address 192.168.0.2". Another technique, called port forwarding allows the NAT router to pass incoming connection requests to different devices on the LAN depending on the type of connection (ie web or mail connection). However, if there are multiple devices on the LAN to which a certain type of connection from outside may need to be established, then neither a software DMZ nor port forwarding will be sufficient.

    Sometimes people (those without network experience) have difficult to understand if their host is or not behind NAT, there is a website that will test to see if you are behind NAT (you need to have Java): (amibehindnat.com).


    The Trouble with NAT and VOIP

    In addition, the way in which conventional VoIP protocols are designed is also posing a problem to VoIP traffic passing through NAT. Conventional VoIP protocols only deal with the signalling of a telephone connection. The audio traffic is handled by another protocol and to make matters worse, the port on which the audio traffic is sent is random. The NAT router may be able to handle the signalling traffic, but it has no way of knowing that the audio traffic is related to the signalling and should hence be passed to the same device the signalling traffic is passed to. As a result, the audio traffic is not translated properly between the address spaces.

    At first, for both the calling and the called party everything will appear just fine. The called party will see the calling party's Caller ID and the telephone will ring while the calling party will hear a ringing feedback tone at the other end. When the called party picks up the telephone, both the ringing and the associated ringing feedback tone at the other end will stop as one would expect. ...

    Fax over IP

    Across the Internet even a G.711 codec fax transmission is unpredictable. An excellent discussion of why faxing and modems don't work well over VoIP can be found here. However, people often get perfectly good results on lightly loaded LANs. It still isn't perfect, as a burst of data on the LAN can still upset things, but some people get results they can live with.

    VoIP and VoIP Service Providers

    What is VoIP?

    VoIP (which stands for "voice over internet protocol" and is commonly referred to simply as an internet phone) is a highly cost effective and reliable way for businesses or even homeowners to make calls across the world or even just across town. The majority of major cable companies that offer bundled internet, television, and phone services already utilize this newer technology, but there are tons of other independent companies that specialize in providing this service to their customers at reasonable rates and with tons of extra features.

    More Than Just Computers

    When people think of VoIP, they generally think of computers due to the popularity of the numerous free communication services like FaceTime and Skype, but this is truly just one aspect of what VoIP can truly offer. It is true that VoIP technology transmits voice communication that's been converted into digital data across a packet-switched network or the internet (what this means, in essence, is that a user making phone calls over high speed internet lines rather than phone lines). With that in mind, users are not confined to only using it on a computer. VoIP technology can connect through the internet using traditional telephone equipment just like a regular line. The phone itself is connected to the internet using an adaptor that's plugged straight into a home or business's internet network.

  • Virtual PBX is a budget-friendly form of hosted VoIP (Voice over Internet Protocol) that usually only handles inbound calls. A virtual PBX is typically intended for small business VoIP customers with fewer than 10 employees and low-volume telephone traffic.


    What Is Virtual PBX?

    A virtual PBX is an economy-class version of hosted PBX. Hosted and virtual PBX systems are business VoIP PBX phone systems that transmit calls over the Internet as data.

    A virtual PBX offers inexpensive business VoIP telephone service to small businesses. As with a hosted PBX phone systems, a virtual PBX is owned and maintained off-site by a VoIP service provider. A virtual PBX enables a small business telephone system to access enterprise-level features such as auto attendants and voicemail. With virtual PBX small business telephone systems, small start-ups, mom-and-pop shops, freelancers, and entrepreneurs can all present a professional image to vendors, investors, and customers.

    Depending on the service provider, a virtual PBX phone system may require a separate phone service for outbound calls.

    Virtual PBX Features


    Virtual PBX phone systems offer lower costs and fewer features than hosted PBX phone services. Compared to hosted PBX small business telephone systems, virtual PBX service is limited to the most basic fundamentals of business-oriented call controls. Virtual PBX is geared toward simple inbound call-routing for SoHo offices with few personnel, small budgets, and limited calling needs. As with many hosted PBX calling services, most virtual PBX phone systems do not require a contract or term commitment.

    Standard features offered with most virtual PBX plans are:

    • Voicemail
    • Auto attendant
    • Unlimited call handling (no busy signals)
    • Call forwarding

    Limitations


    Virtual PBX phone systems generally:

    • Handle only inbound calls
    • Offer a limited number of extensions
    • May not include Fax over IP (FoIP) services
    • Include a set amount of free minutes
    • May not offer voicemail-to-email
    • May not include international long-distance coverage
    • May not offer Internet fax service
    • May charge extra for conference calling

    The features offered vary by virtual PBX VoIP provider. As VoIP service becomes a more common solution for small business telephone systems, many virtual PBX plan features are incorporating the more advanced features of hosted PBX phone systems. Compare plans and prices to determine the best virtual PBX solution.
