In fact, your computer doesn't have to be on to use Vonage. The people you call don't need to have Vonage or the Internet to get your call - just a phone. And when someone calls you, your phone rings as usual.

Setup is easy. Just connect the Vonage adapter to your high-speed Internet and connect your telephone to the adapter.

FOR IMMEDIATE RELEASE
GRANDSTREAM NETWORKS, NEXTIX AND ABOT TANAW PARTNER TO OFFER FREE
VIDEO CALLS TO MILLIONS OF OVERSEAS FILIPINO WORKERS
GRANDSTREAM’S GXV3000 IP VIDEO PHONE, NEXTIX’S NETWORK AND ABOT TANAW
COMBINE FORCES TO OFFER MILLIONS OF OVERSEAS FILIPINO WORKERS FREE VIDEO
CALLING WITH FAMILY MEMBERS
CommunicAsia, Singapore, Booth 5F1-08 (June 16, 2009) - Grandstream Networks, NextIX
Systems and Abot Tanaw are pleased to announce a technology solution for millions of
Overseas Filipino Workers (OFWs) that will enable them to keep in touch with family members
living in the Philippines. The combined solutions enable free internet video calling for millions of
Overseas Filipino Workers and their families living in the Philippines.
The Philippine economy relies heavily on
the remittances that the 11 million
(roughly 11% of the total population)
OFWs send home. Money sent by OFWs
back to the Philippines is a major factor in
the country's economy, accounting for
roughly 13.5% of GDP. In 2008 alone, the
inflow was estimated at $15.9 billion.
Despite the economic contribution that OFWs provide to their families and to the Philippines as a
whole, their absence from their loved ones has resulted in a deterioration of familial relations.
Many lack the ability to speak or see their family members for extended periods of time leading to
estranged relationships, divorce, and strayed children.
To address the negative social impact of migration, the Abot Tanaw Social Media Network was
created. The network enables all OFWs and families to communicate with each other via video
conference for free. With Grandstream’s GXV3000 and NextIX platform the Abot Tanaw Social
Media network has installed this solution at 6 major malls in the Philippines and a video call
center in Hong Kong with hundreds of GXV3000 video phones initially. This network will scale up
to more sites in Philippines and also new video service hubs in Singapore, Macau, and Taiwan in
the future, all offering advanced video communication infrastructure. Through these service hubs,
OFWs in Hong Kong, Singapore, Macau, and Taiwan now have the chance to connect with their
families back in Philippines. The Abot Tanaw Social Media network has provided a full booking
system and management suite to manage calls from Philippines overseas workers who call home
to see their family.
“Abot Tanaw makes accessible to OFWs and their families the means to communicate without
charging them. Using newly developed technology that involves voice and video telephony
services, Abot Tanaw is able to lessen the proverbial toll that separation takes on Filipino
families,” Abot Tanaw Chief Executive Officer Kim Go said.
“We wanted to create an idea where we bridge the distance between OFWs and their families,
[making them] more accessible and affordable. Hearing the voice is good but nothing beats
looking at a face while talking,” says Ephraim Genuino, chairman of Abot Tanaw.
“We are very pleased that our GXV3000 has facilitated the strengthening of familial relations for
OFWs through video-reunion with their family members in the Philippines. High quality real-time
video telephony solutions such as those from Grandstream are revolutionizing the way people
communicate with their loved ones located remotely. We will continue to innovate in this space to
further improve the user experience and affordability of this technology,” says David Li, CEO of
Grandstream.
The project was made possible through the help of the Philippine Long Distance Telephone Co.,
Philippine Department of Labor and Employment and SM Group of Companies.
Don’t miss the chance to see Grandstream’s GXV3000 and the new GXV3140 IP Multimedia
Solutions in Booth 5F1-08 in Hall 5 at the CommunicAsia Tradeshow on 6/16- 6/19.

Skype Messenger - A Forerunner In The VoIP World

2010-01-14T11:48:00.000-08:00

In the Internet world, instant messenger services are mostly offered by search engine

companies. AOL, Yahoo, and Google have their very own instant messaging system that lets users talk, send files and chat freely without any fuss. Yet there exists another instant messaging system that was built independently, and it is now owned by eBay, the largest online auction in the world. It is only known by one word: Skype.Skype was created in August of 2003 and is now solely owned by eBay since October 2005. However, even before its incorporation into eBay, it has been making waves in the instant messaging world by attracting millions and offering services no other instant messaging software has ever dreamt of doing. It’s primarily offering the ability to transmit clear voice calls to individuals at very cheap rates when calling around the world. This is done through its Voice-Over-Internet-Telephony (VoIP) system. Currently there are more than 75 million users, and the company continues to grow. also by this service you can make free call by phone ( free phone call ) .What is it that makes this instant messaging software so popular all over the world? Read on and see what cool services Skype has to offer. You would be surprised at how many services Skype has that clearly rivals other popular Instant Massaging software.Skype has been beneficial to everyone all over the world who wants to make phone calls using their PC. Skype offers very low rates, and anyone in the world can call the continental US for as low as $.024 per minute. This has opened up many opportunities for everyone who wants to establish their business globally. All they need is to buy some credit, and this can be done through PayPal, credit cards, or even bank accounts.Why is it good compared to other service providers like Yahoo? Most VoIP service providers only offer their services to developed countries. If you’re located in a country that’s still developing, you can’t purchase any credits. However, in Skype, you can actually make arrangements wherein Skype can charge directly you bank account.Another cool addition to Skype is Skypcasts. Loosely based on a podcast, Skycasts were created by Skype to accommodate persons who want to hold a meeting online. The unique feature allows people to create a room and freely talk to the moderator or anyone the moderator has chosen to participate. Skypcasts work like an auditorium, where anyone can just go in and listen while the only people who can participate and talk are those chosen by the moderator who also presides in the auditorium. From the Internet to other people’s singing, people can just go in and talk about anything the monitor fancies.Lately, Skype updated its software so that people can also send money through PayPal. If you are a Skype user, you will notice this in the dialogue page wherein you’ll be given two choices if you want to send something. You can choose to send a file or money through PayPal. Who knows what Skype will offer for us next.

software phone calls
Voice over Internet Protocol (VoIP, IPA) is a general term for a family of transmission technologies for delivery of voice communications over the Internet or other packet-switched networks. Other terms frequently encountered and synonymous with VoIP are IP telephony and Internet telephony, as well as voice over broadband, broadband telephony, and broadband phone, when the network connectivity is available over broadband Internet access.VoIP systems usually interface with the traditional public switched telephone network (PSTN) to allow for transparent phone communications worldwide[1].VoIP can be a benefit for reducing communication and infrastructure costs by routing phone calls over existing data networks and avoiding duplicate network systems. Skype and Vonage are notable service provider examples that have achieved widespread user and customer acceptance and market penetration. Other providers are also available. See List of commercial voice over IP network providers.Voice-over-IP systems carry telephony speech as digital audio, typically reduced in data rate using speech data compression techniques, packetized in small units of typically tens of milliseconds of speech, and encapsulated in a packet stream over IP.Can I call using the internet connection?After its introduction, Internet telephony has been highly developed rapidly in a brief period. Many software developers currently offer PC telephony software. However, more importantly, gateway servers are rising to act as an interface between the Internet and the PSTN (It expands as Public Switched Telephone Network). With voice-processing cards, these gateway servers allow Internet telephony VoIP(It expands as Voice Over Internet protocol) users to communicate through traditional telephones over long distances without exceeding "Long Distance" telephone network.A telephone call travels from the local PSTN to the nearest gateway server, which digitizes the traditional, analog voice signal, converts it into IP packets, and moves it to the Internet for transport to a gateway server at the receiving end. This server alters the digital IP signal back to analog and concludes the call locally. With its Internet telephony support for computer-to-telephone calls, telephone-to-computer calls and telephone-to-telephone calls, Internet telephony VoIP represents a vital step toward the merging of voice and data networks.The History and Advances made in Internet TechnologyVoice ove r Internet Protocol (VoIP) is becoming a substitute to traditional telephone service. The goal of VoIP Deployment is to receive the registered location information of a VoIP user to the most suitable public safety answering point (PSAP) through statewide standards using the 9-1-1 network.Most VSPs will perform with a database provider known as a Voice Positioning Center (VPC) and have access to 9-1-1 network through an Emergency Services Gateway (ESGW). VPCs are utilized to update and store registered user location information. . It then imparts the details to PSAPs when a 9-1-1 call is rendered. ESGWs are those Competitive Local Exchange Carriers (CLECs) that supply the connection interface into 9-1-1 network.Initially regarded as just a novelty, Internet telephony is attracting a number of users due to the fact that it offers remarkable cost savings relative to the PSTN. Internet telephony service users can sidestep long-distance telephone carriers and their per-minute usage rates as they run their voice traffic over the Internet for a simple, flat monthly Internet-access fee. VoIP Internet telephony provides a viable threat to the providers of long-established telephone services that should stimulate enhancements in function and cost throughout the industry.On top of the game are Gizmo Project and Skype which rely on a software client on the PC to place a call over the network. This is where one user ID can be used on different computers or in different locations on a laptop. In the middle are VoIP Internet telephony services like Vonage or BroadVoice which also provide a telephone adapter for connecting to the broadband connection similar to Internet telephony services offered by broadband providers, but which are targeted towards sophisticated users and enables portability from one location to the next.Challenges of Internet Telephone SystemsVoIP Internet telephony refers to communication systems services- whether it's the voice, fax or voice-messaging applications that are conveyed via the Internet, rather than public switched telephone network (PSTN). The basic steps involved in originating an Internet telephony service telephone call are conversion of the analog voice signal to digital format and compression or translation of the signal into Internet protocol (IP) packets for transmission over the Internet. With the Internet telephony service, the process is then reversed at the receiving end.Internet telephony VoIP technology still has a few limitations that have stirred some to believe that it is not prepared for ubiquitous deployment. However, many industry analysts anticipated that 2005 was the "Year of Inflection". This is when more IP PBX ports were shipped than traditional digital PBX ports. Therefore even though there are limitations it is no doubt advantegous and helps to a gret extent.One drawback is the failure to forward faxes due to software and networking restrictions. Another stumbling block is the failure to make telephone calls w hen the power supply is inadequate.. Re-wiring is necessary to use the telephone jacks in the typical house. If VoIP is used in solitary LAN (with no internet connection), then it would utilize resources akin to a PABX.Variation in delay is often referred to as jitter. The effects of jitter can be moderated by amassing voice packets in a play-out buffer upon appearance, before playing them out. This evades a condition known as "buffer under run", in which the play-out process runs out of voice data to play due to the next voice packet which is yet to arrive, but enhances delay by the span of the buffer.Tutorials discuss the ongoing brisk evolution of VoIP Internet telephony. The market forces invigorating the evolution and the benefits that Internet users can realize.. It also examines the obstacles that must be cleared before VoIP Internet telephony can be adopted on a pervasive basis. This is a service enjoyed by many.*this page contents gives just informations about voip calling solutions

History of Internet telephony

2010-01-14T11:39:00.000-08:00

History of Internet telephony Voice-over-Internet Protocol has been a subject of interest almost since the first computer network. By 1973, voice was being transmitted over the early Internet. The technology for transmitting voice conversations over the Internet has been available to end-users since at least the early 1980s. In 1996, a shrink-wrapped software product called VocalTec Internet Phone (release 4) provided VoIP along with extra features such as voice mail and caller ID. However, it did not offer a gateway to the PSTN, so it was only possible to speak to other Vocaltec Internet Phone users. In 1997, Level 3 began development of its first softswitch (a term they invented in 1998); softswitches were designed to replace traditional hardware telephone switches by serving as gateways between telephone networks. Revenue in the total VoIP industry in the US is set to grow by 24.3% in 2008 to $3.19 billion. Subscriber growth will drive revenue in the VoIP sector, with numbers expected to rise by 21.2% in 2008 to 16.6 million. The United States' largest VoIP provider is Vonage. Internet Telephony Information.What is Internet Telephony?Voice over Internet Protocol (VoIP, IPA) is a general term for a family of transmission technologies for delivery of voice communications over the Internet or other packet-switched networks. Other terms frequently encountered and synonymous with VoIP are IP telephony and Internet telephony, as well as voice over broadband, broadband telephony, and broadband phone, when the network connectivity is available over broadband Internet access.VoIP systems usually interface with the traditional public switched telephone network (PSTN) to allow for transparent phone communications worldwide.VoIP can be a benefit for reducing communication and infrastructure costs by routing phone calls over existing data networks and avoiding duplicate network systems.

DID will connect a caller directly to the VoIP user, while access numbers require the caller to provide an extension number for the called VoIP user.The Benefits of Internet Telephonywindow.google_render_ad();Retail customers have begun to embraced Internet Telephony as lowered call costs have established themselves. Corporations, small businesses, and even individual customers have reduced their phone bills by supporting full duplex- real time communication.

Examples include:The ability to transmit more than one telephone call over the same broadband connection. This can make VoIP a simple way to add an extra telephone line to a home or office.Conference calling, call forwarding, automatic redial, and caller ID; zero- or near-zero-cost features that traditional telecommunication companies (telcos) normally charge extra for.Secure calls using standardized protocols (such as Secure Real-time Transport Protocol.) Most of the difficulties of creating a secure phone connection over traditional phone lines, like digitizing and digital transmission, are already in place with VoIP. It is only necessary to encrypt and authenticate the existing data stream.Location independence. Only an Internet connection is needed to get a connection to a VoIP provider. For instance, call center agents using VoIP phones can work from anywhere with a sufficiently fast and stable Internet connection.Integration with other services available over the Internet, including video conversation, message or data file exchange in parallel with the conversation, audio conferencing, managing address books, and passing information about whether others (e.g., friends or colleagues) are available to interested parties.Advanced Telephony features such as call routing, screen pops, and IVR implementations are easier and cheaper to implement and integrate. The fact that the phone call is on the same data network as a user's PC opens a new door to possibilities.A major issue preventing VoIP's acceptance by more users is mobility. This is being addressed with new (Wi-Fi)-enabled cordless phones available on the market. With the advent of new technologies such as (WiMAX), it is believed that the mobility issue with VoIP shall vanish.
