The replacement of a PABX for most companies is an expensive exercise and one which they undertake infrequently. In order to make the best possible selection of a new system, it is essential to be familiar with the technology and have a good awareness of new developments and to tackle the project in a structured manner. |

VOIP Telephony is become very popular among the small to medium size businesses. VOIP is the routing of voice conversations over the Internet or through any other IP-based network.
- When should you begin the transition?
- Over what time period should the transition occur?
- Should you transition the entire organization at once?
- Vendor and marketing hype aside, can you build a clear business case to justify the transition?
- Can the benefits and risks be accurately quantified?
|
The decision to move to IP Telephony raises even more important questions:
- Is your network infrastructure ready for VoIP?
- What about facilities?
- What organizational changes will be required?
- What type of service delivery model should you select?
- Hosted? Premise based?
- Should you outsource the implementation?
- Which vendor can best address your business and technical requirements?

ANET Systems frequently undertakes such projects on behalf of its clients and has therefore built up a wealth of experience of the telecommunications marketplace and the various user requirements. Our consultants have an extensive knowledge of the technology along with years of practical experience of implementing such projects. Over the years, we have developed our own methodology for the installation of a new PABX so as to ensure that it is completed on budget, on schedule and to the full satisfaction of the client.
There are a number of key stages involved in the replacement of a PABX and ANET can help answer all of these questions and assist or lead you through every phase: from initial concept and evaluation through every aspect of implementation these are detailed below:
- Develop project plan, Establish user requirements, Equipment specification, Tendering process, Structured cabling, System installation, System change over and post implementation review

| IP Technology Takes Different Forms |
New technology continually brings new capabilities to business communication systems. This new technology comes in different forms.
- Advances and improvements in traditional PBX systems make them more functional and easier to use.
- The adaptation of data networks to carry voice provides ways to converge multiple networks together using Voice over IP (VoIP) technology.
Both traditional PBX telephone systems and IP-PBX systems have their advantages. Much is argued in the marketplace about which is better. The truth is neither is better simply by its nature, but only by its application to meet the individual needs of the organization using it. Simply put, choose the type of system that's best for you. Either way, IP technology is already showing how it can improve the ways in which enterprises operate and reduce costs. |

| IP-enabled PBX Systems |
The rock solid reliability of PBX systems cannot be argued. They almost never go down and rugged digital telephones are equally durable. They offer almost all the telephony features anyone could need. However, while PBX systems support various Computer Telephony Integration (CTI) and IP-enabling applications, converging the two technologies, the telephones operate on a separate network from the organization's data network. This may be an advantage or disadvantage depending upon the amount of IP network infrastructure you already have in your enterprise. However, the advantage is being able to add IP capabilities as needed. IP-enabling these PBX systems provides VoIP trunk access and remote telephone user applications over IP networks, to supplement access through the public switched telephone network. The IP-enabled PBX architecture typically involves the addition IP trunk cards and IP station cards, with Ethernet interfaces, to existing PBX systems as shown in the example below. |

| IP-PBX |
| The IP-PBX that operates in a pure IP environment, is based upon PC server technology, and uses a single network of communication devices and wiring for both data and voice traffic. This network consolidation is assumed to result in decreased network administration, thus making deployment of services and applications easier. However, the appropriate network monitoring and management tools must be in place because the exposure is greater with everything running on one network. The network must also have sufficient bandwidth to provide adequate voice quality for IP telephones. Hosting telephones connected through one IP network, either locally via a LAN, or remotely in any location via a private Intranet or the public Internet, provides the flexibility of distributed configurations and remote telephone users. The IP network will provide all the call switching, regardless of whether calls originate from the public switched telephone network, digital or analog telephones, or IP telephones, as shown in the example below |

| The Best of Both Worlds |
But why should enterprises have to choose or compromise between these two approaches? Why not have the best of both worlds? For most enterprises, the migration path to IP telephony will be a gradual process rather than an event in time. Rather than acquiring new IP-PBX technology through system replacement at higher cost and higher risk, it is expected that most enterprises will integrate voice and data IP traffic into their existing systems as the need arises. This approach protects your investment in existing voice, video, and data networks and represents a low risk migration path.
If you're thinking this way, you're not alone.
- Industry sources show that most enterprises with existing investment in traditional PBX systems prefer this lower cost and lower risk transitional approach to IP integration, accomplished through the addition of IP hardware and software to existing traditional PBX systems.
- This is also a less disruptive approach that enables IP-based services, yet maintains the existing rich set of features and functions as well as the reliability of the circuit-switched PBX.
