I don’t know about you, but sometime I sit and think about all of the electronic devices that I own, and then I wonder how much more they can actually do other than what I use them for.

I know that there are a lot of people out there like me. People that use their devices for their basic features and never really bother maximizing their potential. And then there are people who learn the technology inside and out, utilizing every single feature that is offered.

When I use the term “electronic device”, of course I mean your tablet, your cell phone, your laptop, and even (spoiler alert) your VoIP deskphone! Based on experience, I know that there are a lot of features that your deskphone can do that will probably never get used. Even at the entry level, a lot of VoIP phones today are packed with what can seem like an endless amount of cool options, but that does not mean everyone is dying to try them.

Sometimes, however, there can be features on your phone that can really make your life easier, but may never be uncovered. There is a long list of examples, everything from Do Not Disturb mode, to changing the annoying factory preset ringtone!

For this blog, I did some research and found something that could easily go unnoticed. Something that can easily be turned on and could help people who work in low light situations, or who might not have the best vision.

This feature is setting your phone so that your keypad will light up when in use! And the phone that owns this feature is none other than the Yealink W52P DECT phone!

Activating The Keypad Light On The Yealink W52P DECT Phone

w52pSetting this up is quite simple! If you find yourself in the dark, or not being able to see your phone’s keypad well, just follow these simple steps to light up your phone!

  1. Press the OK button to enter the main menu
  2. Select the Settings icon 
  3. In the settings menu, select Display followed by Keypad Light
  4. Press the Change softkey to check or uncheck the Keypad Light checkbox

And that’s it! Now the next time you need to take your wireless DECT phone into some dark areas, you will have a beacon of light to help you navigate your phone! And maybe…even help you navigate where you’re walking…if it’s really, really dark.

Do you use a DECT phone at work? Is it the Yealink W52P DECT phone? If not, what DECT phone are you using? And does the keypad light up? We want to know!

How to choose your preferred audio device

Choices, choices, choices. Everyone loves choices. Can you imagine a world where the only flavor of ice cream was vanilla? Or the only place to go out to eat was McDonald’s? Yeah, no thanks.

Having choices is one of the things that makes life great, it is a privilege, but having choices when it comes to the things we do every day, is an important necessity. For example, your job!

We go to work almost every day, and for most of us, it’s filled with the same tasks. Maybe moving your weekly meetings to different times can erase some monotony, or changing the order of your tasks can maybe help make things up. Anything to keep things fresh! Einstein once said that insanity is doing the same thing over and over and expecting a different result, and I think there is some truth to that.

For those of us in an office setting, it is almost certain that you have a desk phone, and you more than likely use it often. When that phone rings, we all know there are several ways to pick it up. You can lift the handset, you can answer with your headset, and so on and so on.

But what if I told you that you can have even more choices when it comes to picking up your desk phone? As long as your desk phone is the Cisco SPA 514G! Now, I am not saying that this is the only phone that can do this, but we will use it as an example for the sake of this blog.

Cisco SPA514g

Typically when your phone rings, it is a specific line that is calling you. This will cause one of the line keys to light up! Common knowledge tells us that pressing the active line key will answer the call, but with the Cisco SPA514G, you can decide what device is activated after pressing the line key.

How to Choose Your Preferred Audio Device on the Cisco SPA514G

Telling your phone what you want to answer the call with is actually pretty simple too! Just follow these steps below:

  1. Press the Setup button
  2. Select Preferences followed by Preferred Audio Device and lastly, Edit
  3. Press Option to scroll through your choices
  4. When the option you want is displayed, press Ok
  5. Then press Save

And that’s it! Now, by hitting the active line key on an incoming call, your SPA514G will answer with the device you set it to. The best part is after you get tired of answering the phone that way, you can always change it up! Because of choices.

Do you have a Cisco SPA514G on your desk? Do you use the Preferred Audio Device feature? Tell us what you think! We want to know!

If you have a desk at work then chances are you have a phone on your desk. The kind of phone that is on your desk probably has a lot to do with what your job position and duties.

If you are working in a call center, then odds are you have an entry level phone that is equipped with just enough to get the job done. If you hold an inside sales position then you might have more of a mid-range phone. Perhaps something with programmable BLF keys or HD voice etc.

When you start to get into a job position that has an executive role, then you might have a use for a more high-end phone. A phone that is packed with features that can help you navigate through your day-to-day activities better, oh and a color touch screen too….obviously.

What would be a good example of a phone like this? Ahh, how about the Yealink T48G? When it comes to Yealink’s T4 Series, the T48G is the top of the line. It also has a 7” color touchscreen display, and just about every VoIP feature under the sun. To me, that sounds like the perfect executive phone!

Yealink SIP-T48G

But speaking of every VoIP feature under the sun, there is one thing that you are able to do on the T48S really stood out to me. Not only is this a cool and unique feature, but I feel like it can really come in handy for someone on the executive level who may be in charge of several people in the office.

What’s the feature? The Yealink T48G allows you to upload contact photos! Not only is this relatively easy to do, but it can really come in handy when trying to remember everyone you work with!

I am going to assume that everyone you work with has a company photo, you know, headshots for your website or email signature. These are great to take and upload to your phone contacts. Especially if everyone is assigned an internal extension, it may take a while for you to remember who is calling you.

Doing this can also help you put a face to a name and a face to a voice! So the next time you’re in the breakroom getting a cup of coffee, you can really impress everyone with your flawless name remembering skills.

Now, let’s move on to the how-to part of the blog and find out how to upload contact photos! It’s really quite simple, but it does involve some work on the web user interface. If this is something you need access to or help with, then just let your System Administrator know what you are trying to do, and grab some assistance! If you are able to tackle this on your own, then just follow these easy steps!

How to Upload a Contact Photo on the Yealink T48G

  • Click on the Directory and then go to Local Directory
  • Click Browse, and then locate a photo file from your computer
  • Click Upload Photo to upload the photo
  • You can click Delete Photo to delete the customer photo


Once you have your photo uploaded the next step will be to add the customer photo to the contact! Please note that the Yealink T48S only supports .png, .jpg, .bmp format files and the file size must be less than 5MB!

Now that you have uploaded your photo, all you have to do is follow these next steps and you will be on your way!

  1. Click on Directory and then Local Directory
  2. Click the desired entry you want to edit
  3. Select the desired photo from the pull-down list under Photo
  4. Click Edit to accept the change


And there you have it! Now that you have assigned a photo to your contact, when you place a call to the contact or receive a call from the contact, the touchscreen will display the contact photo! Just repeat the process to keep adding photos to different contacts!

Do you have a Yealink T48G on your desk? Do you use the Contact Photo feature? If so, what’s your experience been like? We want to know!

Whether you are new to VoIP or have been using VoIP for a while, it is pretty easy to say that you are constantly learning new things. Maybe it’s something that you overlooked or maybe it is just keeping up with the latest technology. Either way, no matter how insignificant or major, you can never know everything there is to know about VoIP.

For this blog, I wanted to go over something that might fall more towards the “insignificant” side of things. Seeing as this is a basic how-to blog, it seems fitting. On top of that, believe it or not, we get a ton of calls here at VoIP Supply asking about this simple feature.

What is it you ask? It’s Do Not Disturb! The magic button that basically turns your phone off, without turning it off. A lot of our engineers have reported that one of the most popular support calls we receive is how to turn Do Not Disturb (DND) off.

I am going to go ahead and give a general explanation on how to do this. Remember that not every phone is the same, but when it comes to DND, the method is very similar. For the sake of the blog, we will use the popular Polycom VVX410.polycom vvx410

First, what does DND do? Do Not Disturb stops your phone from ringing and sends all incoming calls directly to voicemail. All calls you receive while DND is enabled are logged under your Recent Calls list.

How to Use Do Not Disturb (DND) on the Polycom VVX410

You can activate DND mode by pushing the DND button on your phone. This can either be a soft key (like on the Polycom VVX410) or in some cases, it can be a line key. Once DND mode is activated, you will notice an icon in the upper right corner of the phone’s screen that looks like this:dnd-icon

If you are new to VoIP, or just got a new desk phone, then I can see how something like this might slip through the cracks undetected. However, turning DND off and restoring all of your phone’s functionality is very simple. All you have to do is press the DND button again!


It’s really that simple. The same way you turned DND on is the same way you turn it off. This can get more complicated if you hit DND on accident or you are not the one who turned it on in the first place. So let this blog be a reminder that if your phone is not working to always check Do Not Disturb!

Now, you may be asking yourself, why would I ever want DND turned on? The most common reason that I can think of is that you are on PTO or vacation for an extended period of time and you do not want your phone to bother your coworkers. If you work in a position with high call volume, then you may even want to turn DND on even if you are away from your desk for a short time, like lunch.

I am sure the list goes on, but by now you should have a pretty good idea of what Do Not Disturb is, and how to manage it! If you have any more questions, please leave them in the comments below!

Do you have a Polycom VVX410? How often do you use DND? What do you think justifies activating this feature? We want to know!

It is hard to imagine a job that doesn’t need a phone. There are an endless amount of different and unique jobs our there, but I’m pretty sure every one of them, one way or another, needs a phone in some capacity of the business.

For this blog, I want to focus on the jobs that are not set in a cushy air conditioned office. Instead, I want to talk about the jobs that need wireless phones, or better yet, wireless VoIP phones.

What is the first job that comes to mind when you think of wireless phones? For me, I immediately thought of a construction job. Because construction can get messy, I would also have to assume that the wireless phones they are using are also ruggedized AND probably even DECT!

What kind of phone could cover all those bases? Well, I’m sure there are several. But for this blog, we are going to use the Snom M85 as an example. This is a wireless DECT phone that can take a beating and will last you a very long time. m85

Aside from this phone’s long range and nearly bulletproof casing, there is one weakness. This weakness is something that all phones have, their buttons. No matter how much of a beating this phone can take, if you press up against something or if you drop it down the stairs, you run the extreme risk of accidental use. Like….calling someone, paging someone, etc.

Luckily, the Snom M85 has you covered with its Automatic Keylock. This is a function that can take the frustration out of your day, and it is easy to manage.

How to Lock and Unlock the Snom M85 Ruggedized DECT Phone

If you would like to lock and unlock your phone manually every time, then all you have to do is:

  1. Press the star key and hold down for at least 3 seconds
  2. A lock symbol will appear in the top line of the display
  3. When pushing a button while locked, the keylock message will appear

See, that was easy! To unlock your M85 after it has been locked all you do is:

  1. Hold the star key down until the lock icon disappears
  2. The phone will then be unlocked and ready for use

That might be the easiest set of directions I have ever seen! But one more cool feature this phone has is the Automatic Keylock feature.

How to Use Automatic Keylock on the Snom M85

This will allow the phone to lock itself if it has not been used in a selected period of time. How do you set this? Again, simple! Just follow these easy steps:

  1. From the menu, select Security
  2. Then select Automatic keylock
  3. From there must select the number of second or minutes. Your choices are 15, 30, or 45 seconds, or 1 to 5 minutes. This will set the inactivity period before your phone locks itself
  4. Press the red End Call key until you return to the home screen

And that’s it! Depending on how long you selected, if your phone is not active, it will lock itself and prevent unwanted phone calls, leaving your phone off the hook, or draining the battery.

To unlock the phone after it has locked itself, just use the same manual steps and hold the star key until it unlocks.

Do you have a ruggedized wireless phone at work? Do you use the Snom M85? If not, what do you use? We want to know! Also, what How-To blogs would you like to see in the future? Let us know in the comments!

It is hard to imagine life without Caller ID. I know I am not alone when I say that I barely know anyone’s actual phone number anymore. Once they are added to my contact list, their name is all that matters.

These days, the same can be applied to your desk phone at work, with the power of VoIP technology, you are able to use your desk phone just like you would use your personal cell phone.

Most of the time, these phones have just about every feature your cell phone has, and in some cases, even more features! I have written past blogs about IP phones having cameras, recording video, and even custom ringtones in the past, so I know the possibilities are basically endless.

But because this is a basic blog that deals with the simplicity of VoIP, I am going to use the Polycom VVX300 as an example. This is an entry-level phone, it has nothing flashy about it, but it is packed with features!


One of these features just happens to be a contact list. You are able to add phone numbers to your VVX300 phone book just like you would on your cell phone. And because we all have that one person who calls all the time, but we never want to answer, you can do more than just ignore the call like you would on your cell phone. You can have the VVX300 automatically reject the call!

How to Reject Calls from a Contact on the Polycom VVX300

To do this is simple. If you absolutely never want to take a call again from an annoying telemarketer, or say, an ex that keeps calling you at work? Then follow these easy steps!

  1. Select Directories from Home view, and select Contact Directory
  2. From your directory, use the up and down arrow keys to select the contact whose calls you want to reject, and press Info
  3. From the contact’s information screen, press Edit
  4. From the Edit Contacts screen, use the up and down arrow keys to select Auto Reject, and select Enabled, and then press Save

And, POOF! From now on, every time that contact calls your Polycom VVX300, the call will automatically go to Voicemail. The one thing this phone cannot do automatically delete your dreaded contacts Voicemails. You will have to do that manually.

Do you have a Polycom VVX300 on your desk? Do you use the Auto Reject feature? If so, who keeps bugging you? We want to know!

The world is full of millions and millions of jobs. A lot of those jobs are very different from one another but it’s also fair to say that a lot of those jobs are similar or at least look similar.

There can be tons of jobs that involve a desk, a computer, and a phone, but that doesn’t mean the people sitting at those desks are all doing the same work. Sometimes we need different programs on our computers, and sometimes, we even need our phones to do different things.

By now I’m sure you are all aware of what desk phone can do these days with the power of VoIP, so I won’t get into the fancy-pants features that some people need, or want, to help assist them with their day to day activities.

What I want to focus on for this blog is something basic that can help tons of people at their job, no matter what their daily tasks involved. That basic thing is programming a line key for speed dial!

Everyone has that one number they call over and over and over again, so adding that number so you can dial it with the push of a button has got to make life a lot easier for a lot of people.


How to Speed Dial From a Line Key on the Grandstream GXP1610

For an example, we will use the Grandstream GXP1610. The steps are quick and easy, and if you can’t access the Web GUI on your own, then simply contact your Systems Administrator or your IT department!

  1. Go to the GXP1610’s Web GUIcenter_1-png-pagespeed-ce-cjuh_q1jz
  2. Go to Settings > Programmable Keys
  3. Configure the Line Key’s Key Mode as Speed Dial
  4. Select the account to dial from and enter the Name and User ID (phone number to be dialed out) for the Line Key
  5. Click on “Update” at the bottom of the Web GUI page
  6. Off hook the phone, or directly press the Speed Dial key to dial out

After completing step 6, you should be on the phone with the number you dial the most faster than ever before! While we used the Grandstream GXP1610 for this blog, you are able to program speed dial to most phones with line keys!

Do you have a Grandstream GXP1610 on your desk? If not, what do you have? Do you use speed dial? We want to know!

WiFi phones are becoming all the rage in the VoIP world these days. If your business uses VoIP service then chances are you have a WiFi phone somewhere in your building.

As I have said in past blogs, WiFi phones are especially useful for warehouses and medical facilities because of their ability to carry them wherever the job takes you. Most WiFi phones have decent range on them, but through in a WiFi access point or two, and you can really go wherever you need in your office and always be able to answer the phone.

While these sound awesome (because they kind of are) they are by no means a ‘plug-and-play’ phone right out of the box. There is some configuring that you will have to do, and of course, you will have to adjust certain things to your liking.

For this blog, let’s talk about the Moimstone MWP1100A. This phone is the real WiFi deal. It has just about everything you will need for your phone, and it looks awesome too. Once you turn the phone on, you’re going to notice the MWP1100A has a beautiful color LCD display. At this point you may want to either crank your brightness or turn it way down, depending on how flashy you want to be.

So I’m guessing that your next question will be “How do I adjust the brightness then?” Well, it’s really simple. If you have a Moimstone MWP1100A and you are looking to change the brightness of your color screen, then just follow these simple steps.

How To Change The Brightness On The Moimstone MWP1100AMWP1100A

Statistically speaking, most of us will spend around 90,000 hours of our lives working. Some of us will spend most of that time in an office, or at a desk. What I can’t tell you is how much of that time you will spend daydreaming about being somewhere else.

While I’m sure it would add up to a couple thousand hours, one thing we can say for sure if that it is important to have things with us at work that remind us why we get up and go through the grind week-in and week-out.

Maybe a picture? Or a souvenir from a memorable trip? No matter what it is, you have to have a little bit of your own personality on your desk, but what about your phone? It is not uncommon for deskphones to display images and if you have a phone that can do this, then you have to take advantage!obihai-phone

There are tons of different IP phones out there! Some of them work similar, most of them are different, but setting your own personal wallpaper is easy! For this blog, we are going to go through how to customize your wallpaper on the Obihai 1032! Just follow these easy steps!

What if I asked you what your most important piece of technology is? You would have to say your smartphone, right? Smartphones have become an essential part of our lives. They are almost an extension of ourselves!

If know everyone, at one point or another, has had that sinking feeling when you reach for your phone and it’s not there. It has to be one of the worst feelings in the world! And thinking about how upsetting forgetting or losing your phone makes you feel has to make you wonder how we ever got through a day in our lives without one!

Now that I have you checking to make sure you have your smartphone on you, my next question is when is it hardest to use your smartphone? I believe most of you would answer that question with “at work!”

Most of the time it is frowned upon to use your smartphone at work, or even have your smartphone out on your desk. This may be why you see so many people with their faces glued to their phones on their lunch break.

Thanks to the rapid pace of technology, there is now an answer to not being able to have your smartphone out at work! The answer is the Grandstream GXV3275. This phone is a smartphone disguised as a desk phone! Everything that is equipped on your smartphone is on the GXV3275. Everything from a camera to applications. This phone is even Android-based, so it will run just like your smartphone.


With that being said, when you are using applications on your GXV3275, they will stay open even if you close them, just like on your phone. Doing this can really bog down your phones speed, and it will do the same to the GVX3275. If you already own this incredible IP phone and didn’t know this, then you might have a lot of cleanup to do!

How to Manage Running Applications on the Grandstream GXV3275

But don’t worry. It’s just as easy to manage running applications on the GXV3275 as it is on  your smartphone, just follow the steps below:

  1. On the GXV3275 desktop, press the Home button for about 2 seconds
  2. Slide the running application to the left or right to stop the application
  3. Tap on the Broom icon to delete all running applications

After cleaning out your running applications your GXV will be squeaky clean! If you would like some advanced options when in the “Thread Manager” then all you have to do is press the applications menu that is located to the right for advanced management options.

Do you use the GXV3275 for your desk phone? Do you utilize all of its features? We want to know!
