Implementing a VoIP-based Network: A Guide

Let’s get started with VoIP

Begin with a plan

In order to successfully implement a VoIP-based network, first we need a plan that addresses your needs. We want to provide you with a phone system that works well for your organization—meeting if not exceeding your requirements. So, we need to know how you want the system to operate within your business.

Which tasks will you be using the network for? This is critical for determining the overall design of your network. If the network will be supporting a call center, voice quality will be a top concern. Alternatively, if the network’s main purpose is to connect multiple offices, then bandwidth and expense reduction may be more important.

With our experience in helping other businesses make the transition to VoIP, we can help you to decide whether you should replace your current system completely or use some of your existing hardware to create a hybrid VoIP and PSTN system.

create a plan

Here’s what we will need to do in order to create a plan:

  1. Learn about your business’ objectives.
  2. Determine the company’s needs and expectations.
  3. Design, create, and test a VoIP solution that meets your needs.
  4. Teach users within your business how they can best use the service.

Key considerations

What are the network objectives?

Think about what you want VoIP technology to do for your company. Are there particular features that you require, such as video conferencing? Consider also features that are not supported by your current system that could be advantageous to your business operations. Are there are any changes within your organization that are prompting the shift to VoIP, such as employees moving to a new office?

The state of your current network should also be considered. Why are you switching to VoIP at this particular time? Is there a carrier contract about to expire, or does the network infrastructure require an upgrade? Is the infrastructure currently outdated?

Right now, what is the environment pertaining to voice and data operations?

To determine how the new network should be configured, it’s important to know what the current network is doing now. Take into account the existing loading factors on LAN and WAN segments, as well as the bandwidth requirements of any new applications you will be using. What are the current call patterns like during busy periods? How do you anticipate growing in the near future?

How much do you value Quality of Service (QoS) relative to cost?

While it is tempting to use cost as the primary determinant of how much bandwidth to purchase, this may not work well for your customers and employees. Alternatively, you can start with a QoS objective for the test network, and determine how much bandwidth needs to be purchased to meet the objective.

How many phones need to be replaced?

Take into account all phones that will need to be replaced, including those that are rarely used.

What is your current Internet connection capability?

For our VoIP solution, it’s necessary to have a Broadband connection. As a general rule, each IP phone uses about 86 kb of Internet bandwidth per simultaneous call. This means that a system with a 1.5 M upload/download T-1 connection can support up to 18 calls at the same time. In general, we recommend that you purchase more bandwidth than you expect to need, to account for overhead and traffic costs.

Studies show that on average, about 25% of a company’s workforce will be on the phone at any given time.

How many phone numbers do you have right now, and how many do you need?

With a traditional phone network, a unique phone line is required for every simultaneous call. This isn’t the case for a VoIP network. You need only have enough bandwidth to accommodate all of your calls, rather than a unique number or line for every phone.

When using an Auto-Attendant, it is possible to have one direct dial number, while all users are assigned an extension. Users will be able to make and receive calls as they like. You can choose which number is associated with each phone.

What does the schedule require?

Decide on major events in the schedule pertaining to your network transition. This includes dates that major equipment will be installed. Everyone should agree on these points.

When will the new system be tested?

Testing is a critical component of setting up a new network. With testing, we can verify that the changes all work on a small group of stations before implementing changes on a larger scale. Therefore, we should plan for testing. The installation and cut-over schedule may need to modified depending on test results.

Implementation: What You Need to Know

This guide will help you to understand the processes necessary for setting up and implementing a VoIP system. The guide also includes guidelines for resolving problems that may come up, escalation procedures, and the duties designated to departments. We want to provide you with the best customer service experience, and for you to understand every step of the process as we deliver your system to you.

Frequently Asked Questions:

What is VoIP and how does it work?

VoIP, or Voice-over IP, is a new telecommunications method. Instead of using a Public Switched Telephone Network (PSTN), like a traditional phone system, VoIP technology digitizes voice input and transmits it as a digital file through an Internet connection. Each telephone uses its own IP address.

Can my business benefit from VoIP technology?

Yes. Whether your business is large or small, VoIP technology provides several benefits. In the long run, using VoIP for telecommunications is less expensive. Users also enjoy advanced telephony options and better audio quality than is possible through a PSTN. Legal services, travel agencies, and real estate offices are just some examples of businesses that can benefit from VoIP.

What services does Xinix provide?

We provide services that enable local, long-distance and Dedicated Internet connections, as your needs require.

Why should I subscribe to Xinix’s hosted service?

Our service allows small and medium-sized companies the opportunity to use VoIP technology without a huge investment in infrastructure and Internet service.  Xinix offers all of the business telephony features necessary for a PBX system, with a simple user interface. Thanks to on-net calling between different offices and bundled services that can be separately purchased, this service saves businesses money in the long term.

What does XInix’s service actually do?

Xinix provides a fully hosted VoIP service, eliminating the need for a location-based phone system. Your business will still have your own network with all of your phone numbers, but at a lower cost and with less maintenance. All phone services are delivered via an Internet connection, and services can be customised to meet your needs.

What are the system’s fail-over capabilities?

The system has been tested for reliability: services are available 99.999% of the time. In the case of a failure, customer data remains stored in the cloud.

How is voice quality affected by the number of users on the system, or users transferring large amounts of data?

When we work with you to set up the system, we evaluate how much bandwidth you require and evaluate the quality of your LAN connection. This means that the system will be set up to handle your needs, regardless of how many people are using the system at any given time.

Which phones will I need to use your services? Do I need to buy new phones?

The service works with analog phones as well as with Polycom IP phones. All phones that we, Xinix, sell are certified to work with our network. We recommend that you use phones from only one manufacturer per location, as this makes the system easier to integrate.

Will the network be secure?

Yes. Hosted communications servers are fully secured. Only authorized users can access the servers.

I have a firewall. How will the service work with that?

There are multiple options for integrating your firewall into your services. VoIP services operate outside of the firewall, and can use a Network Access Translation Device (NAT). The device acts as a gatekeeper and will only allow calls from certain IP numbers through the firewall.

If a single component fails, how will this impact service?

The system is designed to minimize the impact of failures. Any calls that are “up” will remain so in the event of a failure. And thanks to extensive network monitoring, local failures (with a phone or LAN, for example) will have minimal impact.

What about my 800 service?

If you have an 800 service, you will be able to keep or convert it.
