Have you ever looked at your desk phone and wondered why there is a blinking red light? Or maybe a flashing green light? I feel like when it comes to weird blinky things there are two different types of people. Either you just say “Ehh, it’s always been that way” or “why is this blinking! It’s never blinked before!”

Either way, if something is grabbing your attention, then it is probably a good idea to know what it is trying to tell you. Even if it means knowing how to make it stop so the guy next to you with OCD leaves you alone.

No matter what phone you have on your desk when it comes to notifications they are all generally similar. So let’s go over what your phone migh tbe trying to tell you by taking a closer look at the Power Indicator LED patterns on the Yealink T46S.


How to Read the Power Indicator LED on the Yealink T46S

  1. If the phone’s LED indicator is solid red, that means the phone is initializing
  2. If the phone’s LED indicator is fast flashing red, that means the phone is ringing or the network is disconnected.
  3. If the phone’s LED indicator is slow flashing red, that means the phone has received a text message or voicemail
  4. If the phone’s LED indicator is off then the phone is either off, or there are no notifications or activity.

And there you have it! The next time your Yealink T46S is blinking red at you, you should know exactly what it is trying to tell you. This blog covers Power Indicator LED, however, there are many more lights that can flash at you. To learn the full list of indicators and what they mean, check out this user manual (page 5).

Do you have a Yealink T46S? If not, what phone do you use? And are the LED indicators similar? We want to know!

It is no secret that entry-level IP phones are packed with features. They even do more than regular analog phones, period. Even as you climb up the IP phone scale to an executive level phone, it always seems like the phone will have some features that you could never imagine using.

But as we all know, there will come a time where you will need to use something that you never thought you would ever use, and this doesn’t just apply to your desk phone! This happens all the time in our everyday lives. As much as I’d like to blog about the time I actually needed to use a check to pay for something, we have to stick to the world of VoIP!


How to Change the Language on the Yealink T42S

So, today I am going to let you know how to change the language on your Yealink T42S! Doing this is actually quite simple. Just follow these few easy steps:

  1. Press the Menu button followed by Settings >Basic Settings >Language
  2. Press the up or down arrows on the phone to select the language of your choice
  3. Press the Save softkey to accept the change

And that’s it! After you save this change the text on the phone will change to your selected language. This may come in handy for users that need to see a different language other than English because the phone will display the English language by default. Other language examples to choose from are Chinese (Simplified), Chinese (Traditional) and French.

For those of us who use the English language natively, I cannot say when you will actually need to use this feature, but there are many different jobs and situations out there. For example, maybe you have a client visiting your office from overseas and he or she needs a desk and phone to use while they are visiting. No matter what is better to be prepared than not knowing at all! And of course, this could also be used as a pretty funny office prank too.

Have you ever needed to change the language on your desk phone? Let us know, and let us know why you needed to!

After a long wait time, the headset you ordered has finally arrived. You can’t wait to open the box and try it with your VoIP phone but only find that it doesn’t work with your phone!

Urgh… frustrating.  Luckily, your apprehension has been heard!

What the VoIP? There’s been big news in the Voice over Internet Protocol industry. Mary Cheney Marketing Supervisor at VoIP Supply, North America’s leading VoIP solutions provider covers the latest and greatest in the companies VoIP News Update series.

PaloSanto Solutions creator of Elastix shocked many when it was announced that 3CX has taken control of Elastix 5! The move is said to have happened so that the company could shift their focus to Cloud PBX and call center offerings. Elastix has over 100,000 installations worldwide and tens of thousands of monthly downloads. When additional announcements that Elastix 2.5 and Elastix 4 trainings would be shut down effective immediately the bright orange Elastix community seemed to be turning red as customers were shaken up. So what does this all mean? Elastix 5 will be powered by 3CX instead of Asterisk. Elastix 2.5 and Elastix 4 installations will still work and repositories will be available. See our RIP Elastix post for more on this change. For those looking to migrate from Elastix consider Renegade PBX Mini from VoIP Supply.

The VoIP News Update reveals more about the new Yealink T4S series which will feature device performance enhancements, faster response on the phone’s user interface, enhanced speaker performance, and more!

How to solve problems with VoIP
When you’re in the market for a new VoIP system there are many questions that need to be answered, starting with:

  • Would you like to go with hosted service or an on premise system?
  • What software platform would you like?
  • What kinds of features do you need?
  • Does every employee need a desk phone or, can they use softphones?

And depending on where you are in the process, you may not even know what some of these things are.

We Can Help

Here at VoIP Supply we are here to help with plenty of:

  • Learning documents,
  • Case studies,
  • And our one-of-a-kind sales staff with knowledge on all types of systems and deployments.

Case Studies

I would like to share a case study with you that VoIP Supply and Xorcom completed together with Chabot Space & Science Center. We were able to deploy a Xorcom XR2074 along with Yealink phones.

The customer defined what needs he was looking and we needed to find a cost-effective solution because the center is a non-profit organization.

Check out the entire case study here.

New Call-to-action

Yealink IP Phone Family

As the Yealink product line grows and matures into a leader in the VoIP endpoint market, we thought it would be a good idea to give our readers some background on the company that you may not know about them.

I personally think #3 was a great move for the company on a whole to appeal to it’s customer base.

#1.  200 R&D Employees

With that many employees focused solely on creating a better product with the latest features, only good things can happen. Also this means that new products will have little to no bugs/errors that will need to be corrected. They have so many employees to work out all the kinks before it makes it to your desk.

#2.  Microsoft Lync Compatible

The T48G and T22P have already been certified with Microsoft and I don’t think they will be stopping there. With the debut of Skype for Business I can see Yealink moving right along to certify all their new T2 Series and T4 Series phones


Jack of all trades or the master of one? Yealink is trying to be the master of one. They are not looking to add a PBX or gateway or switch to their profile.


#3.  US based Tech Support

Yealink has launched real-time Technical Support Service for North America. With the new service, customers in North America now enjoy Yealink’s prompt and professional services. You can reach the technical support either by email or phone 877.387.2624. The team at Yealink is available Monday through Friday from 8:30am to 6:30pm EST.

#4.  Break Room to Conference Room Phone Options

Yealink offers a phone for the break room, the front desk, the call center employee, the executive and the conference room. They have it all and if there is something they are missing they like to hear feedback from their customers. They want to be the leader and will stop at nothing until their goal is reached.

#5.  Broad Software Compatibility

Yealink, together with our technology partners, has built the Unified Communications Ecosystem Solutions for businesses. These Ecosystem Solutions include On-premise Solutions, Cloud-hosted solutions, and IP Contact Center Solutions.

In this ecosystem, Yealink provides one-stop open SIP terminal solution with customized features, perfectly integrated with the leading IP-PBX, Unified Communications, IP Centrex and Contact Center platforms like Asterisk, 3CX, Tadiran, Broadsoft, Metaswitch and Genesys.

#6.  Focused on Creating the Best VoIP Phone

Jack of all trades or the master of one? Yealink is trying to be the master of one. They are not looking to add a PBX or gateway or VoIP switch to their profile. They are creating VoIP phones and staying on that path. This allows all their research and development people to focus on one thing.

#7.  Cordless Phones with a Repeater

There are plenty of different cordless VoIP phone options for you, but how far is the range? Depending on the size of your office you may not be able to reach all corners with just a typical DECT solution. Yealink has a repeater to extend the reach up to 150 feet! This is a huge gain at the price point and feature set Yealink is offering.

Is there something we missed? Let us know your thoughts, facts, tidbits on Yealink. We would love to hear about them.

Yealink T48G First Look

Yealink is now the #2 SIP Phone Provider and they have every aspect of the office environment covered with their product line of VoIP Phones. They have everything from the break room to the conference room.

  • T21P E2 2-line VoIP Phone
  • W52P DECT Phone Bundle

Simple Cost-Friendly VoIP Phone

The High Call Volume User

We can forget about the high call volume desk work and the executives of the building also. This is when you would deploy the Yealink T29G. This phone looks and acts top of the line for an executive and handle a high volume of calls.

Some of the features include:

  • Up to 16 SIP Accounts
  • Support for Wireless Headsets
  • 10 Programmable Keys with Color (Red/Green)

For a conference room you should go with the Yealink CP860 . It has great range and the ability to add expansion microphones with the Yealink CPE80.

Some of the features include:

  • 10 Feet Microphone PIckup
