VegaStream - Connecting VoIP to Existing Telephone Systems

History 1888 � Common battery system developed by Hammond V. Hayes, allows one central battery to power all telephones on an exchange, rather than relying on each units own battery.

A misconception because after all, VoIP and Internet Telephony use a completely different signalling system to traditional telephony. Therefore a different device must be required to convert those signals into the sounds that make up a telephone conversation. However, it is now possible to install a device; a VoIP gateway between the IP network and existing phone systems that converts the signalling from one to the other.

The VoIP gateway has two distinct roles. The first is to convert the signal so that a person using an IP device can talk to one on a traditional TDM device and vice versa. The second role is to manage the network signalling and routing.

History 1936 � Research into electronic telephone exchanges began and was eventually perfected in the 1960's with the electronic switching system (SES).

For example, all IP devices, including phones, have an IP address while traditional telephones, even extensions on a company phone system, have their traditional telephone number. If a company has connected its traditional telephone system to an IP network, then incoming calls from the IP network will be looking for an IP address. The gateway's job is to recognise the traditional telephone to which that IP address has been allocated and route the call accordingly.

History 1874 � Principal of the telephone was uncovered.

This is just one simple example. Professional-class VoIP gateways, will translate all the sophisticated functions that have been developed in the traditional phone systems such as call forwarding and conferencing.

The better VoIP gateways also feature "pass through". This function recognises the fact that for all its functional advantages and ability to save money, IP telephony is susceptible to catastrophic failure. For example, IP telephony requires a discrete power source, unlike the phones that will keep working even when the lights are turned off. For emergencies, therefore, an enterprise will want to keep at least one phone in each premise attached to the public switched telephone network (PSTN). For example with VegaStream's "pass through" this phone is connected the IP network until that network fails at which time it automatically connects to the PSTN.

History 1900 � First coin operated telephone installed in Hartford, Connecticut.

The Benefits

Cost

With a VoIP gateway, a company can make telephone calls between sites at no cost using the IP data wide area network that it has installed to connects its computer systems. It can also use a gateway to connect its existing telephone systems to an Internet Telephony Service Provider (ITSP). ITSP's use the Internet to radically reduce customers' telephone bills. In both scenarios, employees would use their telephones as normal. There is no training costs, just a significant reduction in the phone bill.

History 1876 � Alexander Graham Bell invents the telephone, beating Elisha Gray by a matter of hours.

Flexibility

Enterprises are beginning to recognise the advantages of a fully converged communications solution. This is where all electronic communications - voice, data, video, instant messaging and email - all pass over a single network. This technology allows for highly efficient and content rich collaboration and interaction and is becoming the de facto standard in customer facing contact centres.

However, while there may be a strong business case for converged communications in the contact centre, the same may not be said for the broader organisation where the significant costs of the existing telephone system may yet to be written off. In these scenarios, the VoIP gateway will provide the solution for a company that wants to make a partial, and gradual, commitment to new converged technology, for example the company can mix and match traditional and IP telephone systems yet all use the telephones as usual.

History 1946 � Worlds first commercial mobile phone service put into operation. It could link moving vehicles to a telephone network via radio waves.

The VoIP gateway is the essential bridge between today's telephone system and the future of converged communications.

Formed in 1998, VegaStream is one of the most experienced players in the industrial VoIP market. The company supplies gateway CPE to both traditional telecommunications carriers and the new generation of Internet telephony service providers. VegaStream also serves the enterprise market through a global network of distributors and resellers supported by regional offices in the UK, USA and Australia. VegaStream is a non-listed UK company.

Meridian Phone Madness: How to Identify Your Meridian Telephone

By Bob Mrozinski

History 1876 � Alexander Graham Bell invents the telephone, beating Elisha Gray by a matter of hours.

Meridian means many things to many people. When people tell me they have a Meridian phone, they feel like they have fully identified their product and that our discussion can spring forward from there. Not so.

Unfortunately, Nortel and Northern Telecom used 'Meridian' across much of their product line. If you have a Northern Telecom or Nortel phone system in your office, it may say Meridian on it. You still need to figure out what the real model number is as well as what system it is running on.

Nortel Networks, Nortel and Northern Telecom have made Central Office phone switches that provide phone lines, Centrex, T-1's, and PRI's. They also make Norstar and Meridian phone systems for business offices.

History 1888 � Common battery system developed by Hammond V. Hayes, allows one central battery to power all telephones on an exchange, rather than relying on each units own battery.

Identifying your phone is the first thing you need to when you want to expand your system or replace a bad phone.

Look at the bottom of the telephone for a model number such as M7324, M7310, M7208, M7100, T7316, T7316e or T7100. Any of these identify it as part of a Norstar phone system.

Meridian, Option One and SL-1 PBX's have phones such as M2008, M2616D, M3901, M3902, M3903, M3904 and M3905. Nortel and Aastra also have Meridian phones. Some of these are M5316, M5208, M5008, M5312, M5216, M5212, M5209, M5112, M5009, M9417CW, M9316CW, M9110, M9116, M9120, M8004, M8009, and M8314.

History 1936 � Research into electronic telephone exchanges began and was eventually perfected in the 1960's with the electronic switching system (SES).

If you don't find model number, look for the part #. It will almost always begin with NT for Nortel or Northern Telecom or an A if it's Aastra. This is followed by several more alphanumeric characters.

History 1874 � Principal of the telephone was uncovered.

Remember, Meridian labelled phones may be on a Norstar system, a Meridian PBX or as part of your Centrex.

I hope this helps you identify your Meridian phone.

Satellite Telephone - What Is It?

History 1877
The very first permanent outdoor telephone wire was completed. It stretched a distance of just three miles.

A Scottish born American inventor Alexander Graham Bell -1847-1922 A.D. - invented the telephone in the year 1876. The telephone underwent many more innovations and today we see a bewildering variety, in very many sizes and shapes flooding the markets. There has been a giant leap in the telecommunications area and today it is possible to send voice, data, pictures, video, stills etc to distant lands at unimaginable speeds in analog and digital formats. Such information can also be transmitted through fibreoptic cable in the form of light waves. Also it is possible to send such information in the form of radio-waves.

History 1876 Alexander Graham Bell invents the telephone, beating Elisha Gray by a matter of hours.

A Satellite phone therefore is a distinctive instrument, which has been devised to enable voice and other data transmission possible through a satellite; in the form of radio waves! There are very many variations of landline telephones and even more variations in cellular phones. Then, what is the need for satellite phone?

The clarity in landline if the voice or data is sent in the analog format, is susceptible to noise interferences. Cell phones depend on cell towers and cell exchanges. If you have to talk to someone 1000 kilometers away in all probability you may have to cross many cells to reach the receiver. Again, if the receiver happens to be in the so-called ‘fringe areas', the reception may not be to your satisfaction.

History 1946 Worlds first commercial mobile phone service put into operation. It could link moving vehicles to a telephone network via radio waves.

Since satellite telephones do not need the existence of cell-towers or cell sites, they go out of the ambit of any geographical dependency and, therefore, it becomes possible to have a dependable and regular communication. They can be used from any place on the globe. Governments and Militaries of many countries are using satellite phones for many years. Only over the last couple of years, satellite phone are being used for commercial and personal use. They can be very handy if you go into a very remote area - a desert or a jungle.

History 1874 Principal of the telephone was uncovered.
