What Does VoIP Mean to My Business? What to Think About When Considering Voice Over IP

There are a lot of thoughts on this topic. Since Cisco began promoting their voice products back in 1998 the common perception is that VoIP solves everything. You need a telephone system? VoIP. Your business has a network? You need to put VoIP in place. Trying to drive more sales? VoIP. The coffee machine needs to be cleaned? VoIP!

Cisco is not alone in this. Our industry is plagued with equipment and services providers trying to squeeze every marketing angle out of this technology. It does bring a lot of flexibility but stops short of cleaning coffee makers or toilets.

What is VoIP?

Simply put, it is taking your voice communications and transforming them into data that can then be transmitted on your network or on the Internet.

How can this help your company?

This technology can be used to connect your offices across the country into one dial plan, using data circuits you may have for other purposes. It can provide a way for the company to have home office workers who are part of the phone system – so that calls can be transferred to and from them just like they were in the office. More advanced applications can be incorporated into your phone system at a lower cost than other technologies. Features such as call recording, voicemail to email, network faxing, and call center are easier to deploy when the system is already aware of your network. Any most typically, the administration of these systems is much easier than other systems due to the fact that many use a web browser or a Windows program to do the heavy lifting. The administrator needs to know less about how the system works to make it do what they need done.

How can this hurt my company?

VoIP adds complication to the way that your calls are transmitted around your organization. Where the voice system was once a separate island with easy to identify issues – it is now integrated into your data network. That means that your network, computers, and phones are all using the same technologies and can impact each other. This usually translates into higher support costs if you do have problems. Network engineers bill at a higher rate and the problems potentially have more sources.

Common Misconceptions

The combination of the promise of new technology combined with marketing fervor makes for some tall tales. What’s the truth?

Voice over IP may save your company money in phone services costs. It may not. It depends on what type of lines you have today and your calling patterns.

VoIP is required to get an easy to use, feature rich system. Not so true. While most of the newer systems that have the better features are VoIP, it isn’t a requirement. Many companies such as Toshiba, Avaya, Inter-tel and others provide advanced features to users of older tech digital telephones. It’s all in the design of your system.

Voice over IP gives you poor call quality. This can be true, however, it is avoided through the careful design and implementation of your system.

In Summary

Voice over IP can help many businesses if applied in the right context. Voice over IP can also be a drain on a business in financial terms and a loss of productivity. Consult with an experienced company that is interested in finding solutions – not just selling a product or service. They can help you leverage this technology to stay on top of your communications while making the most of your investment.

A Few Benefits of IP Phones

In every field of life, people need to interact and communicate. The most easiest and attractive mean of communication is verbal communication. For interchanging opinions through voice, many devices, based on different technologies, are available. One of the striking devices is an IP-phone. The synonyms for IP phones are VoIP telephones, SIP telephones and soft phones.

An IP-phone is the communication device based on VoIP (Voice over internet protocol) technology instead of public switched telephone network. This technology permits the telephone calls to be made over the internet, using a general purpose computer. It works by converting the voice to digital signal and vice versa. It appears like an ordinary telephone or a cordless phone with buttons, display screen and a handset. The handset is connected to the sound card of the personal computer.

The hardware components of the IP telephone include speaker, ear phone or microphone for receiving and delivering voice messages. It possesses ADC and DAC converter for the exchange of voice and digital messages. The other essentials include general purpose processor, Ethernet network hardware and voice engines. The most commonly used power sources are batteries and direct current sources. It requires no separate wiring.

IP-phone is directly connected with the router. After connecting to router, you get connected with the entire information sharing network. All that is needed is a voice over internet protocol software. This software can be bought at cheap rate or can be downloaded free of cost. This adapter takes the simple analogue signal and converts it into the digital signal for its provision to the other end, over the internet.

It provides many alluring features, including many business tools, call management services and other tools, as per the communication needs. It provides call forwarding, call waiting, local number portability, call blocking, FAX, three way calling, Last number re-dial and many other services. It keeps the complete record of caller ID, contact list and the voice mails.

IP-phones have a lot of benefits over any other means of communication. Home and business voice communication has become trouble-free by the use of IP-phones. By using it, one can have easy access to anybody across the globe. It is the cheapest mean of access. You can make local and international calls free of cost. The only expense you have to pay is the internet service provider charges.

On a simple telephonic conversation, only two persons can chat. With an IP phone, on the other hand, you can set a conference call. Thus, you can make extensions, and more than one call can be handled on one access line. It utilizes the compressed bandwidth that makes the transmission continuous and fool proof.

The portable nature of IP-phone greatly increases its popularity. Staying at home, you can access your office or organisation through your IP-phone. You can also customise an auto-attendant. All local and international calls can easily be diverted using IP technology. Moreover, a simple telephone can also be converted into an Cisco IP Phones, using an ATA adapter.

So, IP phone technology is a revolutionary technology that has all the qualities of a sophisticated phone system. It makes your small business impressive and your life easier than ever before.

VOIP Server

Any normal internet connection is equipped for the transmission of regular data, not more complex voice related data. VoIP stands for Voice over Internet Protocol. A VoIP server is capable of providing a complete communication service by which you can send voice messages easily over an internet connection. With VoIP services, people have the option of sending messages and making phone calls via the internet.

Today, one can do a lot of things on the same VoIP server and all in ‘real time’. The more usual services available in the market are based on the standards of the SER (SIP express router) and the ‘Asterix’, these being what allows VoIP to be a lot of things at the same time.

Big advances have been made recently, and in a relatively short period of time. VoIP can offer an ‘all in one solution’ for your business and personal telecommunication needs. Some of the deals available can save just about any business a small fortune, which is probably the biggest incentive for most to get a VoIP server. Especially with regards to online companies.

Different deals cater to different needs. While some will offer a flat rate, others will offer packages of services. As is always good advice, shop around before committing yourself. Some VoIP providers offer better deals for calls made outside your own country; others give preference to national calls.

What do you need? That’s the fundamental question. Assess your company’s needs. Then go looking for the solution. Many of the latest servers include the services of a media server, SIP, a video conferencing facility, and even the ability to transfer a voicemail into an email.

The benefits of having a VoIP based server are innumerable, the features available equally so. For many businesses, this service has already proved to be invaluable. And it continues to be improved all the time. In an unstable financial climate, you have to stay ahead in business. That means watching expenses! An easy solution is to keep communication costs at their lowest.

Time is money. If you seek to create a seamless network of people able to work and communicate remotely in real time, and at a cost you can justify, A VoIP server offers the solution. Usually, no upgrades are required to your computer system in order to get the service running. Although again, that will depend on the on the provider you choose and the computer you have.

Choose carefully, and you can save a bundle. And, who doesn’t like the idea of saving money?

What is SIP Trunking?

White Paper On Sip Trunking – Definition And Benefits

In direct response to frequent questioning on the topic from clients, we have prepared this ‘low tech’ white paper to help you to understand what is happening in this part of the converging worlds of IT and Telecoms. We hope that it is of interest.

1. What is SIP Trunking?

SIP (Session Initiation Protocol) trunking is the technology that is expected to replace ISDN ultimately as the transport mechanism for voice traffic from the PSTN (Public Switched Telephone Network) to corporate telephony systems or PABXs. It provides access to the PSTN using Voice over IP (VoIP) and there are numerous benefits to the end user from cost saving to flexibility and disaster recovery. BT’s 21st Century Network (21CN) is based around the conversion of traditional exchanges to delivering VoIP to all end users and the use of SIP will feature more and more in the years to come.

2. How does it work?

The service provider or carrier will port a subscriber’s number(s) into its own exchange network or hosting platform, which will be located in a secure data centre. These numbers are then re-presented across a private IP network (MPLS, VPLS) or Internet connection back to the subscriber’s premises. Quality of Service (QoS) is essential in a corporate VoIP environment and this can only be offered over leased line, MPLS or VPLS networks. Thus a leased line is provided to connect into the MPLS ‘cloud’, which in turn is linked to the carrier, who will have their links into the PSTN. In addition Virtual Route Forwarding can be set up to provide Internet access from the same leased line connection to reduce costs (See Fig 1, high level schematic).

ADSL Broadband can be used in certain circumstances where user numbers are low, but it does not carry any QoS and should be used in isolation to data services. It is ideal for homeworkers and small branch offices.

The service provider will usually supply both the exchange and MPLS connection as a single product, although in many cases this will be through interconnect agreements and links between different providers (as also happens with traditional telephone lines). The end user will be unaware of who is providing the various sections of their service.

The SIP trunks are presented onto existing PBX equipment, either using an external media gateway or internal software if the system is quite new. The system effectively ’sees’ the trunks as normal ISDN lines, so nothing is changed from the user perspective.

3. What are the benefits?

Typical uses of SIP trunks are:

- Disaster recovery/Business Continuity

The ability to re-present individual DDI numbers to any location is one of the key benefits of SIP trunking. Traditional DDI can only be routed to a single number in an emergency; in most cases, this would mean hundreds of numbers reverting to a single operator, which would be hard to manage.

With SIP trunking, key DDIs can be set up to route to the user’s mobile phone or dedicated landlines in a different location; alternatively, hosted IP PBX extensions could be used as a back up and logged into from any Internet connection. The key point is that inbound numbers are not confined to a single location any more and a variety of plans can be made around this simple change.

- Geographic number portability

Numbers are also no longer confined to the local exchange. If an office relocates to what would normally be a different exchange area, it makes no difference with SIP trunks as they are just re-presented across the new network/Internet connection.

- Cost Reduction

The cost of SIP trunks is approximately ?5 per line per month, against ?17 per line per month for ISDN 30. The leased line connection to the MPLS network must also be taken into account; however, this can be off-set if combined with VRF or an Internet gateway service, i.e. two costs are rolled into one, ISDN and Internet.

There is also a potential saving of thousands when compared to traditional DR services involving the delivery of a lorry with a temporary phone system or an off site disaster recovery location, held at great cost and potentially never used.

4. How will it benefit my business?

There are literally dozens of scenarios where organisations can save money and improve their business continuity plans. Voice is nearly always the forgotten relation when preparing for the worst and yet is usually the operational jugular. Cut your customers’ and support staffs’ ability to talk to you and at best you can expect to flail wildly before collapsing in an undignified heap!

Spink Telecom is helping many clients to understand these benefits as part of an overall review of Information and Communications Technology.

Types of VOIP Phones

There are three main categories of VoIP phones available. In this article we will discuss each type and give you some pointers on the positives and negatives of each. For most users you can setup a voip system at home for a very minimal fee or even for free using services such as Skype you can read our Skype Review for more information.

1. Soft Phone

The first type and generally the cheapest is a soft phone. This is short for software phone. With a software phone, you run a program on your computer that acts as the VoIP conversion device and you input the sound via a microphone and output sound via your speakers. This setup is preferred by users who are always on the go but take their laptop with them. There are a number of voip providers who allow you to setup a soft phone account along with your regular account. You simply enter in the data your voip provider gives you and you are ready to begin sending/receiving phone calls. The downside with a soft phone is that you have to be at your computer or a computer with the soft phone software installed in order to make/receive phone calls. This is not always the most convenient method to use.

2. Regular Analog Phone

With the use of an ATA device, you can plug in your normal home phone handset into a small box that acts as the translation unit between the digital internet signals and the analog voice signals. These devices are relatively cheap (do a search on eBay for pap2 device and you can find a number for less than $50). In most cases these devices require you to have a voip provider service. A number of providers will also include a device for free if you setup your account with them. Check with the providers first to ensure they provide this device if you would like to have phone service throughout your home.

For home service, you can disconnect your outside line and then plug in a regular phone line from your ATA device into a phone jack. This will pass the phone signal throughout your entire house and allow you to use the VoIP service like your normal home phone you are used to having. You will want to find a nice place near your internet router and a phone jack to make this work properly. If you are using DSL this is not a great option for you as you would have the active phone line (DSL requires one). In the case of DSL I recommend a cordless phone that has a base unit and multiple handsets. Then you just plug the base unit in and setup handsets throughout the house.

3. VoIP specific phone

Many companies are not producing VoIP enabled phones that plug in directly to your internet network or can connect wirelessly using 802.11b/g (I would only recommend G or N for this as the connection is much better). You will also want to make sure your phone is not placed near another device that uses radio signals in the same mghz frequency as your phone to limit the amount of interference. These phones are quite expensive for what they are, so if you have the option I would recommend using the base unit and cordless handsets as described in option 2.

Good luck in your search and enjoy the great savings that can be had with VoIP.

Free VoIP Service – Are They True?

When Voice over IP was introduced through the Internet, a lot of the programs available are given free Voice over Internet Protocol services. Unluckily, those great days are gone and these days, these services are not free; but are still given at a minimal monthly charge.

However, after you have decided to buy this Voice over IP services, you would still be astonished with the advantages and benefits that Voice over Internet Protocol gives. Your calls are limitless and you are able to call long distance numbers at free of charge, but you have to settle the low fee.

Don’t be concerned though as there are software’s that give free Voice over Internet Protocol services, among them are Skype and AdCalls. These 2 programs allow you to call making use of the free Voice over Internet Protocol programming.

Skype enables you to make a computer to computer call to Skype users making use of a microphone and a headphone. All you must do is to get free Skype software on their site. This free Voice over Internet Protocol service is only accessible for a computer to computer call and the individual you need to contact will have to get the software as well. If you need to call somebody on their telephone and get a call from them, you would have to buy their credits at a cheap price.

With AdCalls, you could make calls to anybody in the Canada and USA at anytime on their business, home, and cellular phone for free. You are able to call anybody in the world as well on their computer given that they also got the “AdCalls” dialer that could be seen on their site.

Even as a lot of individuals are selecting to use Voice over IP, it has its annoyances, one being the failure to call 911. The explanation for this is that the dial is made from your network instead of a telephone. This makes it not possible for 911 to track your call from the Voice over IP phone and to know your address. When getting your 911 calls, it is not possible for the dispatcher to get any info on your location.

Voice over IP is fast increasing popularity and huge corporations like AOL and Verizon are all giving Voice over Internet Protocol packages. Free VoIP is the popular selection, though these days it is getting harder to find one. For consumers who aren’t prepared or who feel not comfortable w/ going to VoIP, they have the choice of utilizing IM or instant messaging services, for example YM or Yahoo Messenger.

What is Voip Codec?

Codec is an algorithm, usually installed as a program on a server or placed w/in a hardware piece, that is utilized to change voice (in the case of Voice over Internet Protocol or VoIP) signals to digital data to be broadcasted through the Internet or other network throughout a VoIP call.

The term codec comes from composed words compressor-decompressor or coder-decoder. Codec normally get the following 3 tasks:

• Decoding – Encoding
• Decompression – Compression
• Decryption – Encryption

Decoding – Encoding

When you call through normal PSTN phone, your tone is transmitted over the telephone line. But with Voice over Internet Protocol, your voice is changed into signals. The conversion is called encoding, and is obtained by a codec. When the digital voice goes to its destination, it needs to be decoded back to its original state so that the correspondent could understand and hear it.

Decompression – Compression

Bandwidth is a limited commodity. So, if the file or data to be sent out is created lighter, you could send more in a particular time amount, and thus enhance performance. To make the voice less massive, it is packed together. Compression is a difficult procedure whereby the similar data is saved but making use of lesser space. Throughout compression, the file or data is saved to a structure proper to the algorithm of compression. The compressed file is sent to the network and once it goes its destination, it is decompressed to its original state before decoding. In a lot of cases, but, it isn’t needed to decompress the file back, because the compressed file is in a ‘consumable’ condition.

Decryption – Encryption

Encryption is the best tool for achieving protection. It is the procedure of changing the data to such a state that no one could understand. In this way, if the encrypted file is stopped by unauthorized individuals, the data still stays confidential. Once the encrypted file reaches the destination, it is decrypted to its original state. Usually, when the data is compressed, it is encrypted to a specific extent, because it is changed from its original state.

What is VoIP Penetration Testing?

Voice and data has been combined in a way that creates a single network but it has also created a new way for hackers to penetrate computer systems. The integration of voice and data has led to new risks to security that must be addressed with equally new approaches to protecting data. Called VoIP, the voice over internet protocol can be a new management tool for business success or it can be a big open window into your system that’s easy to enter.

VoIP penetration testing is designed to find that open window into the system and close it. Rigorous testing is done on the transmission technologies to determine where it is possible for the system to be breached. One of the mistakes companies make is believing the IP phones and related software have enough security controls built in to them already and they do not need additional enhancements.

How can the VoIP system be compromised or how does it allow unethical and criminal intent be carried out? There are lots of ways and one of them is as old as the telephone itself – eavesdropping. Inadequate security controls can also lead to attackers accessing the server data through the transmission technology, hackers stealing phone calls, service interruptions, and the use of sniffing tools.

When Manipulation is the Goal

VoIP penetration testing is a process whereby an attempt is made to purposely manipulate the VoIP system. All entry points into the WAN and/or LAN are tested and an attempt is made to gain access into the VoIP infrastructure. In other words, security experts try to penetrate both the VoIP system and then use it to see how deep a hacker can get into the computer system itself.

VoIP testing can be standalone testing or it can be one step in a larger security testing program. For example, password weaknesses can be tested for the component VoIP system or for the larger company-wide system. Naturally the broader the testing the more secure the system will be after implementing recommended controls.

With penetration testing, ethical hackers will attempt an authorised penetration of the computer system.

* Test ability to remotely access data network using VoIP technologies

* Look for vulnerabilities in system configuration enabling unauthorised access into system

* Test protection controls at each network layer

* Test remote IP phone locations

* Test ability to add IP address on the VoIP system through remote access

* Attempt to enter the main servers

* Look for ways for hackers to manipulate system at any point including Ethernet and cabling connections

* Look for vulnerability allowing sniffer software able to collect protocols

* Test traffic switching

* Determine if the ability exists to collect VoIP data

* Firewall testing between voice and data including potential for Tunnelling Attacks

* Wireless network security

* Testing of intrusion detection evasion capabilities

Vulnerabilities On All Levels

VoIP technology is relatively new and design of security controls has not kept up with the state-of-the-art technology in many ways. Yet any vulnerability in the voice and data network represents a point of vulnerability on the primary server. The only reason security for VoIP technology has not been a priority is because hackers are just now beginning to turn their attention to this new way to access company data.

Testing modern infrastructures and applications is a complex process. Finding the open window can be difficult because of the complexity of today’s systems and the ingenuity of hackers. It is amazing how often hackers are ahead of IT departments that have large budgets and highly qualified staff and are often able to breach million dollar networks from their garages.

VoIP penetration testing includes testing technical aspects of the system, analysing employee security protocols, completing IT operational assessments, interpreting testing results and making recommendations for security improvements. In other words, it is about mitigating security risks to prevent data loss at any stage.
