Dalton Family Practice utilizes for their telemedicine services. These are the most common causes of poor call quality, and how you can test to see if it might be the source of your connectivity issues:

You can test these aspects of your own network here. Upload and download speeds of at least 2 Mb/s make for the best experience; a latency below 50 ms is ideal, while anything higher than 100 ms is likely to be problematic. Here are some tips for improving your Internet connection at home.

If you are having issues during a call, try closing all unnecessary programs to free up processing power. Restarting your computer before a call is a good way to make sure you are not running any extra applications.

If your equipment is more than 2 to 3 years old, or if it is damaged in some way, it may not be able to support a call. Hardware that is good enough for an Internet video call can be bought for very cheap, consider upgrading.

It is important to keep your computer’s software up-to-date. You can perform a simple check online to see if your browser is the most recent version; you can also find out if your operating system is outdated on a Mac or on a Windows computer.

To have a successful call with someone while using a computer, you must have:

  • a Mac/PC/Linux/Chromebook with camera, microphone, and speakers
  • an Internet connection with at least 2 Mbps download and upload speeds (check your Internet speed here) We HIGHLY recommend anything above 10-15 Mbps to have a better experience
  • Google Chrome, Mozilla Firefox, Microsoft Edge or Safari 11+ (latest release versions)  
  • the latest operating systems, such as Windows 10 or MacOS Catalina, to obtain the latest versions of the browsers listed above
  • Javascript enabled (this is enabled by default, and we’ll give you a message in if you need to enable it)
  • TCP ports 80 and 443 open (sometimes firewalls will block these ports; if you are having trouble connecting while on a workplace network, ask your IT team to check this)

For iOS and Android:

  • Use Safari 11+ on your iOS devices (latest version of iOS)
  • Google Chrome on your Android device

The following are not compatible with

  • Amazon Kindle and other e-readers
  • Voice-controlled smart speakers such as Alexa or Google Assistant

To have a call, you need to give your browser permission to access your webcam and microphone. See browser specific instructions:
