| Microsoft introduced its on-line chat system, MS-Messenger in 2001. Basically it is an on-line direct chat system, where you are notified if a person you have specified is currently on-line. It can be invasive if you are on-line frequently, and signing off the conversation can be difficult. Allows for graphical emoticons. 2006 added voice clips and winks. |

| What is VoIP? |
| VoIP is the ability to make telephone calls and send faxes over IP-based data networks with a suitable quality of service (QoS) and superior cost/benefit. Due to the low cost and increasing bandwidth of the Internet is is possible to have a voice conversation over the Internet. This can mean significant savings in toll calls. The quality of the voice transmission is rapidly increasing. Voice over IP can be done with a microphone, sound card and specialised software, or there are companies that connect a standard telephone to the Internet and work in much the same way as the standard POTS (Plain old telephone system). Growth in the VoIP market is expected to be considerable. Estimations put the annual growth rate for IP-enabled telephone equipment at 132% between 1997 and 2002 with an expected market of some $3.16B in 2002. Annual revenues for the IP fax gateway market are expected to increase to over $100M by the year 2000 (from less than $20M in 1996). |
| Justification |
| The main justifications for development of VoIP can be summarized as follows: Cost reduction. As described, there can be a real savings in long distance telephone costs which is extremely important to most companies, particularly those with international markets. Simplification. An integrated voice/data network allows more standardization and reduces total equipment needs. Consolidation. The ability to eliminate points of failure, consolidate accounting systems and combine operations is obviously more efficient. Advanced Applications. The long run benefits of VoIP include support for multimedia and multiservice applications, something which today’s telephone system can’t compete with. E-phone ( http://www.eph.co.nz/ ) is a New Zealand company specialising in offering VoIP services. Reference : Voice over IP (VoIP) (2000).

| Technical description |
| Basically, it is a term used in telephony for a set of facilities for managing the delivery of voice information using the Internet Protocol (IP). "Put simply Voice-over-IP is a technique that allows voice traffic to be transported across an IP-based data network or the Internet," said David Mason, Product Marketing Manager for Agile, which helped implement UNITY’s system using Avaya VoIP technology. (Avaya is the former Enterprise Networks Group of Lucent Technologies.) "The voice signal is sampled, compressed and encapsulated into data packets to allow it to be switched, routed and bridged along with all other data packets across the Local and Wide area network." Now used somewhat generally, Voice-over-IP comes from the VoIP Forum, a development by major equipment providers such as Cisco, VocalTec, 3Com, and Netspeak to promote the use of ITU-T H.323, the standard approved by the International Telecommunication Union (ITU) in 1996 for sending voice information using the Internet Protocol. For the record, Internet Protocol (IP) is one of the many recognised standards over which data networks send data packets. Other popular protocols include frame relay and asynchronous transfer mode (ATM). When talking about VoIP there are two parts to the story: IP Trunking and IP Extensions. "IP Trunking is where multi-site systems transport telephone calls over their wide area network," explained Mason. "The phones at each end don’t necessarily have to be IP phones. We are simply using IP Trunking to tie the two systems together. Voice effectively travels for free over the existing data network. "IP Extensions, or IP in the LAN, is where the extensions are IP Data devices working off the LAN. They can be multimedia softphones such as Net meeting, or alternatively IP telephones (IP Hardphone) which replicates a traditional telephone." In May 2001, US analyst Frost & Sullivan suggested that the technology will account for approximately 75 per cent of the world’s voice services by 2007. That’s quite impressive stuff but, of course, where IT prophesising is concerned, sometimes it’s better to travel than arrive.

| Voice chat |
| Chat sessions, which are usually text based can be enhanced with the addition of asynchronous (two way) sound, allowing for a web-phone. May be used with avitars to give a sense of reality. The introduction of voice chat will lead to better security as the user will be able to get an idea as to who they are chatting with. eg male or female and a guess at the possible age. |
| UNITY Financial Services (2000) |
| In June 2000, the Wellington-based financial services brokerage UNITY became the first company in New Zealand to utilise VoIP technology in respect to connecting its website visitors to its contact centre while they remained online. It works like this: at any stage visitors browsing www.unitydirect.co.nz can click the ‘talk’ button and speak via VoIP to the company’s contact centre agent who can then answer questions and escort the customer through the site. "It was said that this was impossible for the current state of technology," said UNITY managing director Brian Howard-Clarke. "But I’m a great believer that the impossible is always possible and we sought out partners, Avaya Communications and Agile, who were prepared to make it happen.

| Reinforcing the case for IP Telephony |
| Cost savings, improved functionality and reliability are all cited as potential benefits of internet protocol telephony. But experts advise against hinging your business case on the savings - instead, focus on business process improvements.
