How to Select a Hosted Service Provider

August 19, 2010 by Garrett Smith

Telephony services are perhaps the most important service to any business. What would happen to your business if the telephone system stopped working? This makes selecting a reliable telephony service provider one of the most important IT decisions.

As with any IT purchase, it is important to wade through the marketing information and dig down to the get the answer to questions that matter.  It truly does pays to do your homework!

By asking the right questions up front, you can avoid signing with a risky provider — or one that doesn’t offer what you need. Most VoIP service providers offer basic capabilities such as voice mail or call hold but may not give you the advanced features, service options or scalability that your organization needs.

Here are some useful guidelines on selecting a hosted provider

Evaluate the service provider and system integrators capabilities in terms of breadth of services and flexibility of offerings
There is real value to a business when it selects a range of services from one provider.  IP Telephony services will require an IP connection.  It is also sensible to use the same circuits/network to provide other services.  Remember, the cost of managing separate suppliers is much higher than dealing with one.

Ensure that the vendor is financially stable and committed to the business over the long haul
There are a large number of providers in this market. Some have significant venture capital funding that has to be repaid, often by selling the business.  A large proportion of the rest are operating on a shoe string and some fail every year.  Both of these situations leave you exposed to the risk of no telephony services or one that is altered and not fit for purpose.

Determine what infrastructure needs to be replaced and when
It is not always necessary to replace existing infrastructure; for example, it may be possible to connect the PBX to the IP telephony provider using a gateway.  This will ensure that the PBX is not replaced before it is end of live but it also allows new users to be added to the hosted IP telephony service.  The right provider will make this transition simple.

Look for an IP Telephony provider that has a clear roadmap
This shows a clear commitment to continue to improve the services and add new features.  Technology doesn’t stand still and your provider must be moving with the market.  Unlike a legacy PBX, selecting a hosted telephony solution protects you from the need to buy expensive hardware upgrades to add new products and/or features.

Identify the scope and scale of service provider responsibility
One of the great advantages of selecting a hosted IP telephony service is that it can be a totally managed service.  This reduces your IT resources needed to deliver the solution to the end users.  Other service providers will simply ensure that the voice network is available and the customer will do all the administration.  Select the option that best suits you now and in the future.

Tour the company’s network management facility and meet the people who will monitor the network
When you buy a hosted telephony service, typically the only thing on site are the phones.  Take advantage of any offers to visit the service provider’s data center and/or network management center. Some companies will be proud of their facilities because they know that the investments they have made are about servicing the customer.

Understand the cost models and total cost of ownership
Total cost of ownership (TCO) can be confusing.  Everyone has a way to show that they offer a reduced TCO. However, take an objective view of this and challenge the service provider.  Always make sure that you have added your personnel resource costs and necessary training, both end user and administrator. Remember to include the expected costs of upgrades and adding new services in 2-3 years time.

Select a service provider that has business continuity and disaster recover capabilities
Some providers cut corners, especially when they are in a setup or rapid growth phase.  They don’t have the resources to deploy services at two or more data centers. They have single points of failure in their hardware, software or network. Building resilience into the platform adds cost initially but it is vital to ensure that the service is always available. If an entire data center is lost, what happens to the customer data, call recordings, voicemails?  If these are important to you, they should be important to the service provider.

Obtain fully documented service resolution procedures
Perhaps the heart of a hosted telephony service is the Service Level Agreement (SLA). Make sure you read this before you sign.  Understand what will happen if things go wrong.  You need to be happy with the timescales it could take to get things running again in the event of a problem.  Read the small print, it is there for a reason.

Go for a service provider that has made considerable investments in the technology and support services
Ask the provider how much has been invested in the telephony infrastructure. Some will have invested very little and some may have invested vast sums.  If it is too little the service is likely to be poor.  If it is very high the price is likely to be high, or they need to add huge numbers quickly which will probably mean a poor service as well.  Having the privilege of working with numerous providers I see the effort and support some of the hosted providers we work with put into their business model.   Just because someone has a great website or have flashy commercials doesn’t mean they truly invest in their service.

Ultimately the decision is yours to make but if you need some additional support feel free to give me a call and we can discuss this.  Hopefully I can help clear the muddy waters and help you make the right decision.

How to Design a DECT System

August 17, 2010 by Garrett Smith

If you read my previous post which detailed what DECT technology is, how it applies to VoIP, and the benefits it offers over its closest competitor; Wi-Fi phones, and are interested in building your own DECT solution, whether it be at your home, small office, or enterprise, this post is for you.

Obviously IP DECT solutions offer many benefits to its end users, the first and most obvious is mobility. Most of us have grown accustomed to living in a world where “we can always be reached”, and usually when we find ourselves in a position where we can communicate with outside world, we panic because we have come so accustomed to always being connected.

As it relates to VoIP, mobility is offered in many different ways weather that be via a wireless headset connected to your desk phone, a cordless Wi-FI solution leveraging your existing WLAN, cordless soft phones installed on laptops, or VoIP DECT solutions.

How to Select a Wireless Phone

August 13, 2010 by Joe Shanahan

In previous posts I discussed some of the benefits of wireless VoIP, as well as how to design your wireless VoIP network.

Now it’s time to look into choosing the wireless VoIP phone that is right for you. Before selecting a phone there are several factors that you should consider. Things such as why you are looking for a wireless IP phone, what type of phone you require, who will be using it, what is the budget, and what do you expect and need out of the phone should all be thought out prior to purchase.

The Advantages of DECT Solutions

August 12, 2010 by Brian Hyrek

Wireless communications can be integrated into a VoIP network to increase flexibility of use.

There are a few methods by which a mobile handset can communicate over wireless. Wi-Fi and DECT are the two most commonly used and most debated. Before we get into the advantages of DECT, let’s take a look into what DECT actually is.

What is DECT?

DECT or Digital Enhanced Cordless Telecommunications is a digital communications standard of which is primarily used for creating cordless phone systems.  Digital Enhanced Cordless Telecommunications uses base stations and SIP to connect to your VoIP PBX.

DECT runs on 1880 MHz-1900Back in the early 1980’s, when cordless analog units began to reach European shores from the Far East, techies quickly adorned to the fact that commutating digitally would be better. This meant less crackle and interference, afforded the use of more phones within a small space, a higher measure of security against eavesdropping, the ability to move throughout buildings by passing over between base units, and more.

In the mid-1990’s, DECT technology was beginning to mature and become economically feasible. Quickly, all of the major telecommunications manufacturers hopped on-board and began developing product.  In a nutshell, DECT is a radio access technology.

That’s all well and good but…What’s the big deal?

Advantages of DECT

DECT devices have the advantage of using their own spectrum. This means that there is NO COMPETITION for the use of precious airwaves between computers and Wi-Fi devices.

Another advantage of DECT is that the power required to operate is considerably less than Wi-Fi. In other words…it is possible that DECT can offer you more talk time! Wi-Fi requires more power as it wasn’t originally developed or designed with handsets in mind.

Wait…..there’s more!

Taking advantage of DECT can save you money! Opting for a DECT VoIP solution can save you money. Leading manufacturers such as Aastra, Siemens, Snom, and Polycom all offer great affordable solutions that can cover different types of requirements from enterprise type solutions to residential users. If you have to cover a larger area, there are base stations that offer “roaming” and or “handover”.

Stay tuned as I will be continuing to cover the DECT and wireless VoIP spectrum over the coming weeks!

What you need to know about DECT

August 6, 2010 by Garrett Smith

You all have probably heard the term DECT before or cordless DECT 6.0 before.

All you simply have to do is walk in your local Best Buy, Wal-Mart, or Target and browse the aisle that contains telephones and other electronics. DECT has actually been around for quite some time now, predominantly in the analog world. DECT stands for “Digital Enhanced Cordless Technology” and facilitates a cordless or wireless communication between a base and handset or receiver via a 1.9 GHz frequency range. In most cases, you get around 300ft or so of DECT signaling from the DECT base station. This means that you have a 300ft circumference around that particular base to enjoy cordless freedom.

For the majority of IP DECT solutions, the range doesn’t stop there. These solutions can be accompanied by DECT repeaters which simply transmit the DECT signal strength another 300 ft outwards. In most cases, these DECT repeaters must all reside within the main DECT base signal frequency.

Designing a Wireless VoIP System

July 22, 2010 by Joe Shanahan

In my last post I discussed the benefits of utilizing wireless VoIP in both a WiFi environment and a cordless DECT environment.

Both types provide users the freedom of mobility while still being able to have constant access to their telephone.  Now we will look at how to go about designing and setting up a wireless VoIP system.   Since the cordless DECT phones have a base station that is directly connected to the network with CAT5 cabling, this post will focus on setting up a wireless network for WiFi phones.

VoIP and Your Network

July 19, 2010 by Darren Hartman

Looking to join the ever growing number of businesses using a cutting edge VoIP phone system, but concerned you’re infrastructure is ready?

No need to hesitate with that decision any longer. Ensuring your internet connection and network infrastructure can handle VoIP is relatively easy (unless you’ve got a large complex network).

Let’s take a look at a few things you should know:

  • Available bandwidth – Chances are you already most likely have a strong and reliable internet connection in the office (or else you wouldn’t be reading this). However, a lack of necessary bandwidth to properly transport your VoIP calls has crippled more than a few deployments. This because many fail to realize that VoIP calls are made up of data packets and fail to increase their available bandwidth before utilizing VoIP.
    • Prior to making the switch to VoIP, you should calculate the total bandwidth needed to send and receive your calls. You can do this by multiplying the number of anticipated simultaneous calls times the packet size of the voice codec you will be using (like G.722 or G.729).
    • There are some great bandwidth calculators online that can help you with this.
  • Ensuring and Managing Quality of Service (QoS) – All voice calls are sensitive to interference and since most VoIP calls will be sharing bandwidth with the rest of your data, you may want to prioritize or even segment you voice traffic. Doing this enables you to avoid the following issues which result in poor calling experiences:
    • Latency: Delay of packet delivery
    • Jitter: Variations in delay of packet deliver
    • Packet Loss: Too much traffic in the network cause the network to drop packets
    • Burstiness of Loss and Jitter: Loss and discards (due to jitter) tend to occur in bursts

Once you’ve taken a look at each of these items in relation to your current internet connection and network infrastructure, you should be a good position to move on to the next steps. This includes:

  • Increasing bandwidth
  • Replacing or expand your existing network infrastructure

When it comes to the second item, your networking infrastructure, it is important to know that the switches and routers of today are for more advanced than the ones you may be running. Today’s networking equipment come with features that allow the shaping of traffic and tools to ensure QoS.

They’re also nowhere near as expensive as you might think, so if it’s been a while since you’ve upgraded your network, you should definitely take a look at what’s currently available.

So don’t let your current infrastructure scare you away from VoIP. If you take into account the factors listed you are going to stop any issues before they start.

SIP Trunking With a VoIP Gateway

It’s certainly true that IP telephony offers a much more robust telephony experience than traditional analog telephony. However that robust experience often comes with an upfront expense.

So what if you’re not financially ready to invest in a VoIP PBX?

You’ve still got options.

VoIP Service providers most commonly offer SIP Trunking in order to allow you to make VoIP calls using your phone system – either analog or VoIP. If you’ve never heard of a SIP Trunk a good way to think of it is as a phone call routed over the IP infrastructure of a carrier using VoIP technology. Today SIP Trunking is the standard transport method for VoIP calling.

For your business utilizing SIP Trunking means you no longer no longer need a PSTN connection or costly PRI/BRI’s. Electing to take advantage of SIP Trunking affords the opportunity for smart and cost effective solutions such as only requiring one connection for both data and voice.

After a bit of research, you may have decided on a SIP Trunking provider that best suits your needs.

This leads us to how exactly you leverage SIP Trunking with your existing PBX.

For that you’ll need an FXS VoIP gateway.

SIP Trunks can be brought in to an Analog or Legacy PBX via a FXS gateway. In a prior blog, I had touched upon FXS and skimmed the possibilities of an FXS gateway. FXS, Foreign Exchange Station, is a telephone interface which supplies battery power, provides dialtone, and generates ringing voltage. FXS devices must connect to an FXO device such as your Analog PBX.

Connecting an FXS Gateway to Analog PBX

Take a look at any Analog PBX and you will notice FXO ports on the actual PBX. An FXS gateway will be connect to these ports in a 1 to 1 type setting. Meaning, If you have 8 FXO ports on your Analog PBX, you will require an 8 port FXS gateway to connect to the SIP trunks.

Take a look at this diagram on SIP Trunking via a VoIP Gateway:

FXS Gateways come in a range of sizes from 2-24 port to suit businesses of all sizes. They can also be used in conjunction with one another to scale even higher.

All in all, it is possible to “save” your recent investment in an analog PBX or further your communications experience with SIP Trunking while not being able to financially support an IP PBX.
