Business Phone Line Options

By: John Shepler

One thing every business, large or small, needs is at least one telephone line. Phone lines may seem pretty mundane, but you may have more options than you think. Are you sure that you have the right phone line for your business?

Plain Old Telephone Service
The historical phone line that we’re all familiar with is the analog phone line, also called POTS for Plain Old Telephone Service. It’s that vanilla.

POTS lines are as simple as they come. They consist of a single twisted copper pair that runs from a standard RJ-11 phone jack on your wall all the way back to the telephone company central office. The phone conversation is carried by a varying current in the wires.

What you may not realize is that POTS is a self-contained phone system. Phones were traditionally made of passive electrical components. They got their power right off the phone line… and still can. The value of this is that even if the electrical power goes off at your location, you still have phone service.

What’s happened lately, however, is that even single line phones have gone electronic and require AC power supplies and/or batteries to power the circuitry. This is especially true of cordless phone systems with multiple handsets. You can still get dial tone during a power outage, but you need to have a backup battery supply to operate the phone, not the line.

Multiple LInes
You are not stuck with just a single POTS line. You can have as many as you want. Mind you, there is no economy of scale. There is a fixed price for each line whether you have one phone per line or share the outside lines using a Key Telephone System or PBX.

Wireless as an Option
Can you get rid of the telephone line completely? That’s what cellular phone service is all about. No more “landline”. Everything is done with cell towers instead of wires. Wireless can work just fine for independent professionals who are always out of the office anyway. With a data plan you can have both Internet and voice telephony on the same device. You can enhance your mobile setup with an incoming toll free number, fax transmission and reception, and international dial-around calling. Shared plans can support a small office as well as a single user. Operations larger than that will still need wired landlines.

Moving up to Trunks
A telephone trunk is multiple phone lines coming in on a single cable. There used to be analog trunks, but that technology has all gone digital. The most popular trunks are T1, ISDN PRI and SIP.

T1 lines were devised as replacements for multiple analog POTS lines. Instead of separate wires, T1 lines are multiplexed to divvy up the available bandwidth into 24 independent channels. Each channel can be thought of as a separate phone line.

What if you already have a dozen phones and want to replace all those separate phone lines with a single T1 line? Chances are that you’ll get the same or better service at a lower monthly cost. A box called a “channel bank” handles the conversion between T1 channels and analog lines. Just plug your phones in like you always have.

T1 vs ISDN PRI
ISDN PRI or Primary Rate Interface is a variation on the T1 line. It uses the same channelization scheme, but dedicates one channel to dialing and switching for all the others. That means you have a maximum of 23 outside lines available on a PRI trunk. The tradeoff is that your phone calls will switch faster on ISDN PRI. That’s important for call centers and others who need highly efficient telephone operations.

Most PBX systems now have the interface circuitry for T1 and ISDN PRI already built-in. You simply plug in the trunk line and the system handles all of the necessary conversions.

SIP Trunks
Many, many companies are considering switching to VoIP technology or have already made the move. SIP trunks are the natural complement to VoIP phone systems. Their advantage is that they use the same protocol, SIP, as the phone themselves. Remember that VoIP or SIP phones connect directly to an Ethernet LAN, usually shared with computers, printers and other network devices. The SIP trunk extends the network so that it also connects to the VoIP service provider.

Like T1 and ISDN PRI, SIP trunks support multiple simultaneous telephone conversations. The difference is that these conversations consist of packet streams all combined on one line instead of breaking the line into separate channels.

Another advantage of SIP trunks is that they can carry Internet traffic as well as phone calls. After all, everything is in packet format. What’s important is that the trunk be setup to prioritize telephone traffic over data traffic to ensure voice quality. This is called Class of Service or Quality of Service.

What phone line is best for your business? One way to find out quickly is to get multiple competitive quotes for everything from POTS through SIP Trunking as business phone line options.

Best Way to Manage Your Phone System: Get Rid of It

By: John Shepler

What is a common denominator for all businesses? Telephones. What’s a common denominator among business phone systems? They need to be managed. Well, what if they didn’t? Would that be a load off your mind and a competitive edge for your business? It certainly could be. Let’s see why. Even more importantly, let’s see how.

The Trouble With Desk Sets
The legacy business phone is a heavy black box full of analog circuitry and connected to the phone company its own telephone “line”. Today, the phones are lighter, some have digital circuitry, others are cordless with multiple handsets. They still have their own unique “telephone” network wiring.

When you have a single phone or a cordless set with several handsets, managing the phone system is no big deal. There’s really nothing to manage. If you’ve got a dial tone, you’re good to make and receive calls. The one thing you might add is a backup battery if the phone has an AC power adaptor. Legacy analog sets get their power right from the phone line. Newer electronic phones, especially the cordless variety, have DC power supplies that plug into the wall.

Management headaches begin when you get a number of phones sharing outside lines. Sure, each phone can have its own outside line, but that gets real expensive real fast. Plus, not everybody is making outside calls at the same time. Some are calling within the company. Many are not on the phone at all.

Types of Business Phone Systems
The two most popular types of business phone systems are Key Telephone Systems (KTS) and Private Branch Exchange (PBX).

Key systems let you call between phones inside the company using only your internal telephone wiring. That’s a big advantage over independent phones because the telephone company will charge you for every call that has to go through their network. The limitation of KTS is that each line has its own button on every phone and has to be manually selected to make or receive calls. That limits the practical number of outside lines to typically 4 or 6.

Private Branch Exchanges are little phone company switches within your business. You can still make internal calls through the PBX without using an outside line. The PBX system manages a pool of outside lines that are shared among all the phones in the system. The number of lines you need depends on what percentage of employees are making or taking calls from outside the company at the same time. A dozen lines can often serve dozens of users.

Why Get Rid of Your Phone System
Someone in the company, and it may be you, is responsible for telephone expenses. These include local and long distance charges, the cost of purchasing and maintaining the phone system, plus moves, adds and changes to your telephone assets.

The cost of “moves, adds and changes” comes from the fact that each phone has a dedicated line that goes to the KTS or PBX. The connection tells the system which phone is picked up or needs to ring. If you want to move a phone to another desk, you have to also move the connection in the phone wiring or reprogram the system so that it knows the new location. Otherwise employees have to change phone numbers every time they are relocated. Add a phone? You’ll need to add a phone jack at that location and a line back to the system.

The larger the company, the more phones there are, the more phone wiring there is to wrangle and the more expensive the phone system becomes. Worse, if your company grows beyond the capacity of your system, you’ll have to upgrade it if possible or rip it out and put in a new one if not. At some point the technology will become obsolete and it will get really pricey or impossible to keep the beast running. Then you are looking at a major capital investment.

How to Get Out of the Phone Business
Whatever business you are in, it is probably not the telephone business. You simply need those phones to get your job done. Even call centers are focused on the services being provided and not the telephone equipment itself.

What if you could just buy or rent the telephone sets as you need them, plug them into your existing computer network and let somebody else worry about buying and maintaining all that expensive switching equipment?

You can with a service called Hosted PBX or Hosted VoIP. Both mean the same thing. VoIP is the technology that turns telephone sets into network peripherals. Like all computers, the phones have their own internal address on the network. They can be plugged into any network jack and will work just fine. No need to change any wiring.

There is no KTS or PBX on your premises. A much larger “Cloud” system is located at the service provider’s data center. All you have on-site are telephone sets called SIP Phones and a special router or call controller to direct phone calls to the provider. You no longer need outside lines to the phone company. Instead, you have a digital SIP Trunk that connects your location to the provider.

The Pay as You Go Advantage
What’s happened is that you have traded a large initial investment in a phone system and the ongoing costs to maintain it and make changes for a simple “cost per seat” for each phone. Some providers include all new SIP phones when you sign up for service. They’ll send more when you expand the business. No need to pay up-front for phones and lines that will sit unused until you need them. If you need to downsize at some point, you return the phones and stop paying for the ones you no longer need.

Advanced Features
Chances are that your existing business phone system doesn’t have the ability to include smartphones or integrate with computers for efficient call center operations. You many not even have the functionality to support auto attendants or hunt groups for multiple agents for your call center. The hosted system will not only have many more advanced features that what you probably have now, but will be kept up to date as new features are offered. You never have to upgrade your phone “system” because the system is provided for you in the cloud.

Are you feeling limited by the functionality, inflexibility or high costs of your current phone system. Before paying a small fortune to upgrade your in-house equipment, take a closer look at Cloud Hosted PBX Business Telephone Service.

The 3 Types of VoIP Lines for Business

By: John Shepler

Businesses large and small have been migrating to VoIP telephone technology for years now. Some are delighted with the move and have never look back. Others feel like they’ve lost something in the way of performance. The calls are often muddled and it’s hard to carry on a two way conversation. Would you believe that its the exact same technology involved? Why is it that VoIP telephony can range from excellent to unacceptable? Let’s take a look.

What’s VoIP
VoIP or Voice over Internet Protocol is a means to convert telephones into computer peripherals. The reason to do that is both to save money and enable applications that just won’t work on the old style telephone network. Network voice is a powerful tool, but can more easily be degraded that simpler analog phones.

Old School Phone Systems
Business phone lines are sometimes called POTS for Plain Old Telephone Service. They consist of twisted copper pair wires that run directly from the phone set all the way to the telephone company. Each phone has its own set of wires. Once you get more than a few phones, however, you face a mounting phone bill since the telco charges you to make internal as well as external calls.

Companies get around this by installing their own phone switches. Small systems use Key Telephone Systems where multiple outside lines are available on each phone but you can also call within the building on your own wiring. Larger companies install PBX (Private Branch Exchange) switches that manage a pool of outside lines that can be assigned to any phone as needed.

If you only have a couple of phones, each with their own line, the phone company takes care of all the switching for you. With many phones, you become your own little phone company for inside calls. That means you have to take care of all the special phone wiring and the Key or PBX switching equipment. Plus, you have to pay for multiple outside analog lines or a digital PRI trunk to get to the public telephone system.

How VoIP is Different
With VoIP, each phone plugs into your company LAN. That gets rid of the second special phone network. You still need something to switch the calls between phones. This can be a VoIP PBX or IP PBX that you have in-house. It can also be a much larger hosted PBX system from a hosted VoIP service provider. Hosted means that a specialized company “hosts” or run the system. You are one of many clients that they host. It’s pretty much like buying web hosting. You simply pay by the month for service instead of having to install and maintain your own equipment.

VoIP Phone Line Needs
All VoIP phones connect to a local network. This can be a small home office network that has only a computer, WiFi router, VoIP phone adaptor (for a regular phone) and broadband modem. Or, it can be an extensive corporate LAN that is bridged into multiple business locations nationwide and even overseas. The principles and the requirements for high quality performance are the same.

Since the network is shared with many phones and other computing devices, it take some doing to make sure that you get high performance. With dedicated analog lines, that’s the phone company’s problem. With VoIP, it’s now your IT problem.

What’s needed is plenty of bandwidth to accommodate all the phones and other devices. But that’s not enough. You need to give the voice packets priority over data because phone calls will start sounding muddled and choppy long before you notice that the file is loading slower. The network also needs low latency, packet loss and jitter to be transparent to the packets carrying the VoIP digitized phone conversations.

3 Types of VoIP Phone Lines
All analog phone lines are alike. All ISDN PRI trunks are alike. VoIP phone lines can be quite different. They range from Internet VoIP to SIP Trunks to MPLS private networks.

Using the Internet as Your Phone LIne
The low end of the market, which keeps costs low for home offices and small businesses, uses a broadband Internet service to connect to the VoIP service provider. You can share your broadband connection with a couple of computers, a WiFi router, and a few VoIP phones. You’ll need a router that creates CoS (Class of Service) to prioritize the phones or the computers will interfere with your calls. Sometimes the service provider will give you an adaptor that does this.

The advantage of using the Internet as a phone line is that it’s cheap. You probably already have broadband for your computer. The lure is to save money by “eliminating the separate phone line.” The downside is that the Internet was never designed for telephony. It was intended to reliably transport data files. There is no prioritization of voice on the Internet and most access lines, like DSL, Cable, Satellite and Cellular, are shared broadband. It’s a cost vs performance tradeoff. You may find that some calls sound perfect but others break up or sound muddled. It all depends on what else is happening on the Internet while you are making your call.

One way to improve Internet VoIP is to use a dedicated Internet access (DIA) like T1 or Ethernet over Copper. This keeps your neighbors from disrupting your calls while they download large video and software programs, but you are still subject to network congestion on the Internet itself.

Private Line VoIP Service
Companies that depend on high quality phone service for customer support and employee productivity usually sidestep the Internet in favor of something more predictable. The outside line that compares most closely to the legacy analog and PRI lines is the SIP Trunk. This is a digital broadband line, but it is a private line that is not shared with others. It’s called a SIP trunk because it supports SIP or Session Initiation Protocol, the switching system for VoIP calls.

A simple SIP trunk is a T1 line that runs from your network to your service provider. It supports up to a couple dozen simultaneous phone conversations or a combination of phone calls and Internet. The Internet service has a lower priority than the phone calls and uses whatever bandwidth isn’t needed for the phones at any given time. Smaller companies that don’t have dozens of phones find this is a great cost saver compared to maintaining separate phone and broadband lines.

Larger SIP trunks are also available for bigger companies or call centers. Both copper and fiber optic bandwidth is available to support as many calls as you need.

Voice over MPLS Networks
Major corporations generally have many business sites located around the country and even in other countries. They still want any employee to easily call any other employee without paying long distance toll charges. They also need to make outside calls to anyone with a phone.

A sophisticated solution is called VoMPLS or Voice over MPLS networks. MPLS is a private network arrangement with a regional, national or international service footprint. The network operator ensures that each paying customer has the necessary Class of Service, bandwidth and low latency, packet loss and jitter that they need for high performance.

VoMPLS works a lot like VoIP using SIP Trunks. The difference is that instead of having to run dedicated private lines among all your locations, you simply need an access line from each location to the MPLS network. This can give you a major cost savings, especially on those long international connections, while maintaining high network performance.

Are you in search of a better telephone solution, to reduce costs, increase available features or both? If so, there are VoIP telephone solutions you should take a close look at.

Packet Voice Moves to the Cloud

Many businesses and individuals have already switched to VoIP for their telephone service. The original impetus is a cost savings over legacy phone service. Beyond that, enterprise VoIP services offer the opportunity for reduced staff and maintenance coupled with a richer feature set. Just when you thought that VoIP was a settled technology, a new wrinkle comes along. That’s VoIP up in the cloud.

Why move your phone service to a cloud? Let’s take a look at why this might be advantageous to your company and how we got from the old-timey candlestick and desk sets to something as amorphous as a cloud.

A generic technical term for VoIP technology is packet voice. Packets are a computer network protocol most often associated with Ethernet. A packet is a self-contained piece of data that has all the information needed to get it from source to destination. Packets are packets. It doesn’t matter what’s inside. Packets can carry voice, images, video, data and whatever else you can reduce to binary digits.

The major technical leap in packet voice is changing from a switched circuit telephone network to a packet switched network. Switched circuit means that every telephone call has an electrical circuit set up to connect the two (or more) phone sets involved in the conversation. This is unique to the public telephone system and has been that way since its inception. All telephone activity was originally voice calls made between electrically passive telephone sets. Look at one of those old phones. Do you see an AC cord? No way. The electrical power for the call was supplied by batteries at the telephone switching center.

When computer networks became more prevalent than telephone networks, the idea of what a network is changed dramatically. Both telephone and computer networks can run over twisted pair copper wire equally well. What’s different is that computer networks don’t set up and tear down electrical circuits every time that one piece of equipment wants to exchange data with another. The circuits that connect each computer device are continuous. What is switched is the data packets themselves. Ethernet switches or routers ensure that packets get to their intended destinations without having to create new circuit connections on the fly just for a single or group of packets.

Here’s why that’s important. VoIP or packet voice is transported over computer networks rather than switched circuit telephone networks that are only used for telephones. By connecting the phone to the LAN, you can eliminate the separate telephone network. All that wiring and the personnel needed to maintain it and change connections as phones are moved, added or deleted goes away. The cost of running the telephone network also goes away.

Something much larger doesn’t go away. That’s the switching system needed to interconnect telephones, even those using packets, and connect to the Public Switched Telephone Network (PSTN) for outside lines. That specialized switching system is most often called a Public Branch Exchange or PBX. Small businesses with few phones and outside lines may use a simpler system called KTS or Key Telephone System. Those are the phones with individual line lights that tell you if a particular phone line is being used or available for your call. Medium and larger companies have the more automated PBX equipment that manages both internal calls and multiple outside lines.

This is where the cloud comes in. An in-house PBX system can be set up to work with legacy analog phones (switched circuit) or the newer IP telephones used for VoIP. You can connect the phones and PBX to your computer network to eliminate the separate telephone wiring, but you still have to make connections to the public phone network if you want to take or make outside calls. PBX systems aren’t cheap, either. They require a major investment, ongoing maintenance efforts and the likelihood that you’ll have to replace the one you have when it goes obsolete or runs out of capacity.

Why not move that PBX to the cloud the same way that you move servers from in-house to the cloud? That’s the idea behind Hosted PBX, also called Hosted VoIP. The hosting is done by a very large packet voice switching system located at a cloud service provider. You don’t have to buy this system, maintain it or worry about upgrades and obsolescence. That’s the job of the cloud service provider. You simply pay a monthly fee for each phone or “seat” that you need.

Ironically, this concept takes us back to the early days of telephony when there was a large central switching system that connected to each telephone. The difference between the old “Ma Bell” approach and Hosted VoIP is that you are no longer tied to the single phone company that owns the phone wires. You can order network connections called SIP trunks to connect to any cloud provider you want. VoIP technology also allows new applications that integrate telephones and computers, important for call centers and contact centers.

Packet network technology has enabled computers to network within companies and all over the world. This technology is now being used to transmit video conferences and telephone calls on the Internet and private network connections. The rise of cloud computing companies takes packet switching equipment to the next level by moving the central hardware to the cloud, where it can be managed by specialized service providers. The advantage to you is lower costs and more features.
