By the Numbers: 3 Great Tools for Successful International Conference Calls

International conference calls or conference calls with participants in two or more time-zones can be a challenge with common questions like: What is the base way for Dieter to dial in from Berlin; Is Mary in Vancouver 3 hours

Australian Central Time Zone
Global Time Zones are confusing at best and it is difficult to tell what time zones use daylight savings time and when they are in effect.

ahead or 3 hours behind my time or; does Sydney, Australia observe daylight savings time (the answer is yes, from the first Sunday in October to the first Sunday in March, western Australia does not however).



When planning your next international conference call keep in mind these 3 useful tools to get everyone connected at the right time and eliminate confusion.

  1. Call Me and Viewer Apps. Dialing out to participants can be cumbersome using touch tone dial out within a conference call, but Mercuri delivers with two unique web app options to help:
    Call Me
    Any Conference Participant can call themselves into your conference call with this handy web app.

    Participants can dial out to themselves using our Call Me page. They simply enter their participant code, name, and set the country code and enter their phone number (and extension if applicable), then click connect. Call Me shows you the progress of the dial out. When the participant’s phone rings they simply answer and join the call.

    The host can dial out to participants using Mercuri's web based conference viewer.
    The host can dial out to participants using Mercuri’s web based conference viewer.

    The Moderator can dial out to any participant with the Conference Viewer. Like Call Me, just enter the name, set the country code and enter the number (and extension if applicable) and then press Call or Sidebar. Sidebar allows you to speak to the participant before they join the call while Call will immediately join the participant to the conference call.

  2. Numbers page: Our Numbers Page lists all our global dial-in accesses either alphabetically or closest to the user geographically. Toll Free, Local and National dial ins are listed for over 100 cities and 50 countries as well buttons for Skype direct link and our web audio dial in.
    Global Meeting Time Zones
    Hosts can set their local meeting date and time and see the corresponding date and time anywhere around the globe.

    As the moderator use the numbers page to get valuable time-zone information. Just set your meeting date and time at the top of the page and then see the meeting date and time local to any of the dial-in accesses by clicking the Globe icon button next to the number. This amazing new feature calculates the time of the meeting to any listed local number for the scheduled time of the meeting! You’ll never have to worry about how many hours ahead or behind a participant may be, or if or when daylight savings time comes into effect as the scheduled meeting time will always be accurate for all locations! As a participant the numbers page link is included in all invitation emails sent out by Mercuri so that each participant can quickly and easily find the best dial-in number option for to use.

  3. Outlook Conference scheduler : Use our Outlook App to schedule your conference call right from Outlook using your Outlook Contacts. When you use Outlook with Mercuri’s Conference Scheduling App you set your meeting for your local time
    Selfcare Invitation
    Use our Outlook App or Selfcare Web App to invite participants to your conference call . The invitation will adjust to each participants local time settings and contain all the necessary information to join the conference call

    and when you send out the invitation each participant will receive a calendar invitation that automatically adjusts the meeting time to their local time-zone based on their computer’s settings. Each invitation automatically includes the link to our Call Me and Numbers pages so everyone can join easily and on time. A similar email invitation web app is available in our Selfcare Website


These tools are available to all Mercuri’s customers and are already on your Mercuri account. Visit our Youtube Channel or our Website and contact us for more details!

International Conferencing: A Primer for Success

At Mercuri we pride ourselves on providing the simplest, most user-friendly conferencing experience possible. Recently we heard from some of our customers about a little confusion around the best way to conduct an international conference call.

Global Conference Call
Conducting a conference call with participants all over the world is not as difficult as it seems.

Conducting a conference call with participants all over the world is not as difficult as it seems. There are some simple steps you can take before the meeting to ensure everything goes according to plan.

Most of our clients connect to their meeting via a toll-free 1–800 number. However, these numbers often do not work outside of the US and Canada. In some cases the number can be called and and connected but your local carrier’s long distance fees will still apply, defeating the purpose of a toll-free number. So what’s the best way to get around this?

Here’s the good news. Mercuri provides local and international toll-free numbers in over 100 cities and 50 different countries, which are available at Conference planners can reference this page beforehand, or include the link in their meeting invitations so participants can choose the best option for their location. For convenience these links are included in Mercuri’s Outlook Scheduling Tool and the online Self-Care utility.

Access Numbers
Mercuri provides local and international toll-free numbers in over 100 cities and 50 different countries

International toll-free numbers work best when called from a landline, because not all mobile carriers have agreements with international providers. If the participant must use a mobile phone we recommend test calling the toll-free number in advance to ensure everyone is connected on the day.

If landlines and mobile phones are both unavailable, Skype is an acceptable last resort. We strongly recommend using a headset and microphone instead of your computer’s built-in mic. Although Skype offers a VoIP dial-out feature, you’ll have a better quality call by connecting directly to our Skype contact “mercuri.bridge1”. Mercuri also offers an HTML5-based application for connecting to conferences from your browser, which is available at

So what happens if you’re trying to conference with someone in Tuvalu or Burkina Faso? Countries with poor telecommunications infrastructure rarely offer international toll-free services, and Skype may not be an option as high-speed internet is required.

In a scenario like this the best option is dialing out to the participant. Mercuri offers several solutions for automated dial-out:

  • Self-dial-out is available is available at Participants enter their passcode, phone number and select the country they’re located in. A dial-out can be scheduled ahead of time, so when the chairperson starts the meeting the participant will be called and connected to the conference.
  • Chairpersons can use the Conference Viewer to dial-out to participants anywhere in the world. For a more detailed look at he Conference Viewer, check out this video.
  • If the participant is in an area without internet access the chairperson can request that touch-tone dial-out be activated on the account.
  • An operated-assisted conference can be arranged in advance. Our operators will dial-out to the participants and ensure everyone is connected to the meeting properly.

International conferencing can seem like a daunting task, bit with a little preparation and care it can be as easy as the average phone call. If you have any questions about the specifics of you international conference don’t hesitate to contact your Mercuri representative. We’re always happy to help.

And it’s a good thing I wrote that idea down, because I’ve forgotten it already.

Sound & Fury or: How Your Webcam Mic is Driving You Mad

Has something like this ever happened to you?

You dial into a meeting. You’re connected quickly and everything seems okay. You’re not really here to do anything of import, just listen to the conversation, only contributing if it’s absolutely necessary. At some point it becomes necessary so you un-mute the mic in your webcam, say your piece and mute the mic again.

Unwanted Projector Fan Noise
You’ll never hear it but a projector or other device near your laptop can generate unwanted noise into your laptop microphone.

Someone asks you to repeat yourself. They heard you speaking but your voice was broken and overwhelmed by the fan on your desk. You repeat yourself. Same problem. You have no idea what’s going on, and your very unhappy about it. But don’t worry, there’s a simple and inexpensive solution to your problem.

Your webcam was never built to provide high quality audio. The microphone was added as a selling point, not a dedicated tool. It’s small, positioned too far away from your mouth, and is by necessity an omni-directional microphone. That means it’s not just listening to the words from your mouth, it’s listening to every little sound in the room. The same goes for the mic built in to your laptop.

So a webcam mic is out, but that’s not a problem because you’ve already come up with a solution. Aren’t you clever. Your smartphone came with a pair earbuds that have a little microphone attached to the cable. Perfect, you think, This should solves all of those little problems. If only things were that simple.

Those earbuds solve problems like ambient noise and poor mic placement, but you’re still facing the biggest problem of all: your computer’s sound card.

Laptop Earbuds
Earbuds plugged into your laptop still use the laptop’s sound card.

Like the microphone in your webcam, your sound card wasn’t built to be anything special. It handles audio playback well enough but the mic components are often thrown in as an after-though. They exist so a user can do the most basic sort of sound recording; talking into a microphone and playing it back at a different time. Conferencing demands simultaneous audio recording and playback, which your stock sound card wasn’t designed to handle. Speakers and microphones generate sound through an analog process while your computer only understands digital signals, so the sound card has to translate these signals. To save the manufacturer money the playback and recording conversions are handled by the same circuitry. The sound card’s primary function is audio playback, so when it’s required to deal with playback and input at the same time the input quality tends to suffer.

So how do we solve this? It’s simple: don’t use the sound card.

USB headsets are designed for real time communication. The headset contains its own very tiny sound card, which uses separate circuitry for encoding input and decoding playback. You computer won’t have to do any of the processing internally, which frees up power for heavier tasks like a video conference or desktop share. Most importantly, a USB headset puts the microphone right next to your mouth. It doesn’t have to be omni-directional or boost the gain to hear your voice. You talk, the headset listens, and sends sends impeccable audio into your conference call.

USB Headset Works
A USB headset is the only web audio solution that works!

A USB headset is a simple and inexpensive tool to improve your web conferencing experience. You could stomach the poor audio from your laptop’s microphone, or wonder with increasing anger why your white earbuds don’t do the job any better. Or you could spend a little money on a headset and not have to complain again. Trust me. Go with the third option. It’ll be the best fifty bucks you’ve ever spent.

Mobile vs Landline or: Wait, Can You Hear Me NOW?

In the late 1980s a major US telecom boasted their call quality was so exceptional that “you can hear a pin drop”. Twenty years later, another telecom bragged they could offer “fewer dropped calls” and repeated over and over the phrase, “Can your hear me now?” It wasn’t a gimmick, it was an honest question, and it paints the perfect picture of the shift from landline to mobile communications. No one disputes the benefits of mobile phones, but it’s undeniable that the technology trades quality and reliability for convenience.

In the past few years the prototypical cellphone has all but disappeared, giving way to smartphones, text messaging, and always-on internet connections. Mobile calls are shorter and less frequent than ever, so the diminished quality and reliability tends to go unnoticed… until you want to participate in a conference call.

Mobile Conference Call
Surrounding noise like the radio, wind or traffic will be picked up by a microphone.

Your typical conference call is an hour long, connecting five, ten, twenty or more people. In this environment call quality and reliability are paramount and cannot be assured by a wireless network. Moreover, the portability of a mobile phone means you’re seldom in a quiet place while making a call. You’re likely somewhere in public, or in the car using a speakerphone. And while your phone’s speaker maybe be louder than its earpiece, you’re using the same microphone in either mode. Your phone simply boosts the volume of the input, meaning it will pick up not only your voice, but any little noises within a few feet of the microphone. That means your radio and engine, as well as road noise, wind from and open window, and the sound of other traffic. Muting the line can help if you only need to listen, but if you’re planning to talk avoid mobile speakerphones all together.

The landline is almost a thing of the past. Consumers have switched the cable-based home phones and business is migrating to Voice-Over-IP. Carriers are constantly handing calls off to each other through cost-saving measure called Least Cost Routing and have combined their voice and data networks into a single pipe. All that considered, landlines are still regarded as having better call quality and reliability than any mobile service.

Keep in mind that every piece of the puzzle, from your headset to your phone to your service provider, plays and important role in the quality and reliability of your call. A little knowledge can go a long way to ensure a top notch conferencing experience.
