How to Wall Mount an AT&T Merlin Phone

Tuesday, September 1, 2015

If you buy an AT&T Merlin phone that comes ready to sit on a desk or have one in your office that you need to hang on the wall there are a few steps required so the handset will not fall off once the phone is hanging on a wall.  

First, pick up the handset you will see a clear rectangular piece of plastic that holds in a white piece of paper where people write their phone number or extension.  Remove the plastic overlay and piece of paper.  You will then find a flat head screw, this needs to be removed.  Once the screw is out, you can take the tab out of the phone. The tab will then need to be reversed 180 degrees and reinserted.  Finally replace the flathead screw and other accessories. This will help the handset not fall off when it is hanging on the wall. 

There is also a special stand that attaches to the bottom of the phone so it does not tilt like it would if it were being used on a desk. If you are placing an order for an AT&T Merlin phone and need it to hang on the wall let us know and we will send the wall base.  

How Do I Change Time on Avaya Partner 18D Phone?

Wednesday, July 29, 2015

Every year, twice a year America is forced to change the time on all the clocks.  While this is easy to do on some appliances at home like a microwave, it is much more complicated to do on electronic items such as a business phone system.  One of the most common phone systems out there is the Avaya Partner system which often uses the Avaya Partner 18D phone with its nice LCD display.  

Avaya Partner ACS Phone System                                           
Must be done from extension 10 or 11.
  1. Press Feature and dial 00.
  2. Press the left intercom button twice.
  3. To set the time, press # and dial 103. Enter the correct time using a 24-hour format.
  4. To set the date, press # and dial 101. Enter the correct date using MMDDYY format.
  5. Press feature and dial 00 to save.
So for example, if you need to set the time for 09:00 PM you would type 0900.  If you do not get around to changing the clock in the evening at 05:00 PM you would enter in 1700 for 5PM. 

AT&T Merlin Phone Systems

Wednesday, July 29, 2015

Back in the 1980’s AT&T was the biggest manufacturer of business telephone equipment.  Their number one seller was the AT&T Merlin phone system.  It was a huge improvement over the much larger business phones of the time.  The Merlin phones were extremely well made, so well so they are still on the market today.  The Merlin system allowed for users to place multiple calls on hold, had music on hold, and was flexible with the number of lines and phone extensions. 

Today there are still many companies that have the Merlin phone system from the 1980’s. While over time these users may have replaced phones or handsets, no one can argue about how overall reliable this system was.  Unfortunately, we are coming to a time so distant from when this system was manufactured that the phones greatly outnumber the available systems on the market. While Merlin BIS-10 phones are still plentiful and working, the older Merlin Classic 206, 410, and 820 systems are much harder to come by.  These systems, even if found, are not as reliable as they were when originally created having problems such as bad power supplies, warning lights, and calls bleeding over. 

Merlin Classic Phone System

Merlin Plus Phone System

AT&T Merlin Plus Phone System

AKA Known As 206, 410, or 820

AKA Known As 820D or 820D2


There is a solution for the time being, the Merlin Plus system.  The AT&T Merlin Plus phone systems are compatible with the Merlin phones that are used on the Merlin Classic systems.  The Merlin Plus system is different than the Classic in some ways. The Plus has music on hold built and does not require a Feature Package.  The Merlin Plus system uses 4x0 line cards and 0x10 stations cards.  Each 4x0 line card will provide you with four incoming lines.  You can use up to 2 4x0 line cards per Merlin Plus system to allow for up to eight incoming lines.  Then you can have up to 2 0x10 station cards, each card allowing for up to 10 phones for a maximum of 20 phones per system. 

The Merlin Plus system is a great alternative to keeping your Merlin phones going versus having to upgrade your whole system.  You will be able to keep your existing phones and wiring in your building and swap the Merlin Classic system for the Merlin Plus system.  Manuals for these systems are available online for free as PDF files and you can always hire a professional to make the change for you.  

Nortel T7316e and Caller ID

Wednesday, July 29, 2015

Common Question:

Does the Nortel T7316e Phone Handle Caller ID?


It is not about if the phone can handle caller ID, it is about if your Nortel system can.  The Nortel T7316e phone will only work if connected to a Nortel phone system regardless of phone service.  If your Nortel phone system is an MICS or CICS with a CI caller ID card the display will show caller ID.  If you have a Nortel BCM system, then this phone will also show caller ID.  The older Nortel systems like the 824 and 616 will run this phone but will not show caller ID even if you have caller ID through your local phone company.  

If you do not have a Nortel phone system this phone will not work at all for you.

What is E-Waste

Wednesday, May 1, 2013

E-Waste is also known as electronic waste and can range from any electronic item from a television, computer parts, to your telephone system.  With technology always evolving and more and more people becoming dependent on electronic items (especially cell phones), the amount of electronic items ending up in landfills is astonishing. There have been many companies throughout the US which have been in existence for many years but are growing in popularity over the years which handle the proper disposal of these kinds of electronic products. They strip the products and recycle what they can for gold, copper, and other metals.  The plastics found as the casings on electronics are not recyclable, and the whole process is very tedious.  

Here at Business Telephone Sales we buy a lot of phones and equipment that people are no longer using, but we do not buy all of it.  I get asked all of the time what to do with equipment that no one wants.  As the "green movement" grows fewer people want to just throw away their old phone systems and them end up at the dump like typical food waste.  

The kicker to this situation is, people want to help the earth but at what cost.  In Sarasota County, where we are located, residents can drop off household electronics at the Sarasota County's Household Chemical Collection Centers.  However, this is only open for residents with proof of address and if you have a copier you must go to one specific location and it will cost you to dispose of it.  With this economy most people are not going to go out of their way to drop off a copier and then have to pay for it to be properly disposed of.  On top of that, I would guarantee most people in this county have no idea these specific centers even exist!  I had to look to find them.  There are plenty of people who donate such items to Goodwill, Habitat for Humanity, and other charitable causes and that is awesome. With donating someone may be able to reuse your product and that completely eliminates the waste altogether, and if not the responsibility of properly disposing of these electronic items falls on them.

Now, to businesses.  I have found a very helpful link from the US Government's Environmental Protection Agency's website which will show local places for business to properly dispose of their electronic waste.

Also, I have come across a woman owned business in San Diego whose motto is, "Creating a GREENER today from Yesterdays world!" Her company is trying to make recycling easier for everyone. You can find out more about Envirogreen Recycling Services and what they can do to help those in the San Diego area at  

All over the internet there are states, cities, and private companies advertising how to get rid of unwanted electronics, now we just have to promote this valuable information.  The easier it becomes for companies to be responsible in this area, the more common practice  it becomes the less full of toxic battery waste and other such harmful toxins the much better off everyone will be in the future.  

Please take time to find out how to get rid of those left over phones that we did not buy from you before just throwing them in a dumpster.  

Sustainability – The Ability To Endure, To Maintain, To Support

Monday, April 29, 2013

More and more these days the term “sustainability” is a topic I hear about and read about when it comes to the earth, producing food, going green, etc.  Many corporations are now producing “sustainability reports” showing the details of how they are incorporating the “three pillars of sustainability” into their daily operations. 

The Three Pillars of Sustainability is to overall reduce the negative impact humans.

  1. Managing the Environment which falls under the ecological way of thinking of sustainability
  2. Managing Human Consumption of resources such as food and products which is the economic approach to sustainability as well as the running out of resources
  3. Political and Cultural Concerns

There are environmental costs for using many resources; and scientists, inventors, and people are trying to find alternatives so we don’t run out of resources.  Everyone is responsible for making sure there will be healthy food to eat, clean air to breathe, and products to buy to maintain a certain quality of life. 

Here at Business Telephone Sales we have been continuously working to improve our efforts in creating a sustainable business plan.  The measures we have taken have become easy and second nature to all who work here and can be easily copied by other companies as every little bit to save the earth, keep items  out of landfills, and help reduce production of new items helps when you add it up.  A lot of these methods also save the company money and in now way compromise our quality services we provide.

Examples of some of the sustainability methods used daily at Business Telephone Sales:

  1. Items such as boxes, copy paper, and paper products like toilet paper and paper towels all come from recycled materials. 
  2. Our printer we use has the lowest cost of ink and prints the most pages using the least amount of ink and this actually saves us money and helps us go through less products. 
  3. We try our best o reuse any parts we can from defective phones such as housings, buttons, plastics, and accessories whenever possible. 
  4. All defective “greenboards” get recycled professionally as well as all used cords we receive in. 
  5. The boxes from incoming shipments go in our cardboard recycler. 
  6. Glass and plastic bottles get recycled. 
  7. By purchasing used phone systems they don’t end up in landfills and get reused.
  8. For those systems we do not purchase we provide resources to help the customer find local ways to recycle their electronic goods
  9. Our warehouse does not have air conditioning (fans help to cool the Florida summers)
  10. Promote car pooling
  11. All computers are set to energy efficient power down cycles
  12. Get rags cleaned professionally to reuse versus using disposable

Life Without Telephones Horrible! Just Imagine

Monday, April 15, 2013

Communication has evolved over time starting with smoke signals, to letters, then the telegraph and now look at all the ways we have to communicate with one another.  When Alexander Graham Bell started working on improving the telegraph in the 1870’s he used his knowledge of sound and music to create a device which could transmit speech electronically and then further improved it to allow users to make multiple calls at the same time over the same wire.  Today, in 2013 we still heavily rely on telephones with many improvements being made over the past 140 years.

Personal use of phones has grown from having one single phone per household to each person in the home now possessing an individual cell phone. Telephones have enabled families to keep in touch whether they live in the same city or a different country.  Phones have helped to cultivate and maintain relationships.  Besides just personal use of phones and teenagers keeping up with the social gossip, businesses also utilize phones for professional reasons as well. Modern day telephones and business phone systems allow transferring calls, placing people on hold, and having multiple people on the same call.  Phones are used to answer basic questions and allow companies to join together from great distances to create complex contracts and business transactions.

  Inter-tel Axxess Phones                                          

Without the use phones these businesses would not be able to   communicate these long distances.  Even   with the Internet, there are enough scams and seedy companies out there, I   get calls all the time with people saying, “I just want to talk to a real person.”  Without the human to human correspondence its   like life as robots.  People and   communication is what keeps business going, and phones play an integral part   in keeping up human communication.

 "Life without phones may be quieter, but certainly not as interesting."  --Melanie McGill

Personally, we at Business Telephone Sales use the Nortel phone system.  For the last 15 years we have used the same system successfully without feeling the need to get caller ID or call forwarding to a cell phone as we are here in a single location from Monday-Friday during normal business hours. These days there are many sophisticated phone systems available on the market.  Whether you are like us and continue using an older system or have a newer system with more bells and whistles, can you imagine what the world would be like with no phones?  It would be impersonal, full of texts and emails with no ability to detect tone or have that ability to fully connect.  Void of emotion, lacking customer relations, ultimately eliminating that personal touch.  Life without the telephone is not a way I want to conduct business, it is a tool just like many others to help you successfully maintain your business and personal relationships.

Have you seen the latest Discover Card commercial?  It discusses this exact topic.  A lady was calling Discover and she got a real person over the phone.  The whole commercial is discussing how neither the customer nor the Discover rep like dealing with "machines" and "robots."  Technology has gone so far, companies are now having to advertise getting a live person over the phone versus an auto attendant to deal with customers.  

Why Buy Refurbished? - Financial Aspect

Thursday, April 4, 2013


In today's modern world there is rarely a day which goes by that there is not a new modern innovation being promoted. Everyone is in a rush to get the newest "toy" to stay current. So why buy refurbished? When it comes to buying phones for your business, there are mainly two types of consumers. There are those who already own a phone system and want to maintain it, and there are those who are starting out and need a low cost phone system to get their business off the ground. Refurbished products can assist both consumers greatly.

In regards to the already established business, the consumer can save up to 80% off of buying new. However, most of the older phone systems out there are no longer being manufactured. I get asked all of the time if I have a particular phone, like the Nortel T7316, brand new. The corporation Nortel went out of business a few years ago. While there may be a handful of brand new Nortel T7316 phones on the market, the vast majority will be have been used. The consumer can spend countless hours hunting down a new phone which will cost triple what a refurbished phone would, buy a refurbished replacement which are plentiful on the market, or completely upgrade their phone system to something that is brand new (which will costs thousands of dollars, plus having to learn how to use the new equipment). Refurbished equipment is restored to like new condition and are under warranty resulting in a money saving advantage to those purchasing refurbed phones to maintain their current systems.

Those companies who are just starting out looking for a low cost   solution to buying brand new will be more than satisfied with refurbished as   they will still have money in their pockets to help fund other necessities in   running a business. You can purchase a completely refurbished phone system   for a few hundred dollars depending on your demands. The more demands like   caller ID and voicemail raise the purchase price, but still will never   compare to a brand new system.  As long   as the customer realizes their requirements up front and is clear when   purchasing the refurbished system all that is left is to hire an installer to   program it.

With the above being said, this article is only dealing with the financial savings to the costumer and not relating to the fact these products being refurbished are not ending up in a landfill as these sorts of electronics will take millions of years to biodegrade. Look for future posts on e-waste and how Business Telephone Sales cares about the earth and the steps we take to maintain our “green” philosophy.
