When evaluating free conference call services, it's important to consider the features and limitations of each service. For instance, many free conference call services do not offer high-quality video, so if you need high-quality audio and video conferencing, you may want to look elsewhere. In addition, free conference call services often have hard limits on the number of participants they will accept. Free conference call services also have additional security risks. Because these services use the internet, they can be hacked. Hackers have even been known to use these services to run scripts to automatically call numbers on a regular basis. This means your calls may go unnoticed. It's important to make sure you have a secure and reliable phone number to prevent unwanted calls. If you don't want to pay for an expensive service, free conference call services are a great choice. These services are often free, and they are ideal for startups, small businesses, and businesses with remote team members. Some of the services even offer a mobile app for free. This is a great way to reach remote team members without spending a fortune. BlueJeans was ranked one of the best free conference call services during winter 2019. Their free 7-day trial gives you the opportunity to test the service and see if it suits your needs. BlueJeans features include HD video, Dolby voice, real-time insights, and a full suite of identity management tools. While free conference call services may be tempting, it's better to go with a paid service if you need more features. Some free services have limited functionality and are not as user-friendly as paid ones. Additionally, you might have to pay for the convenience of dialing out from a live event. When choosing a free conference call service, make sure it has call controls that suit your needs. You should be able to manage participants, manage recordings, and mute callers. You should also be able to see who's available and control their volume levels. This will ensure a smooth conference call flow. When choosing a free conference call service, make sure you know whether or not you'll be charged for long distance calls. The cost of long distance calls will depend on your long distance plan. However, most free conference call services don't charge any setup or usage fees. Therefore, it's a smart idea to consider this option if you regularly need to make a lot of these calls. Google Hangouts is another option for free conference call services. The Google app lets you schedule meetings with up to 25 participants. It doesn't provide a phone number, but you can give callers your Hangout weblink. You can also use Google Voice to give callers a virtual phone number so they can call in. Google Hangouts also comes with standard call controls, including the ability to mute other callers and share a screen.
