How do I use Webex with no internet connection?
Some Telco providers in various regions are experiencing higher than normal call volume. If the phone number that is provided is temporarily unavailable, choose from one of the other numbers assigned to your site. Follow the instructions during the meeting join or from the Webex Meeting invite to find the global call-in numbers.
- Open your meeting invitation and call one of the numbers under ‘Join by phone’.
- You may be asked to say your name and/or ‘press 1 to join the meeting’ on your keypad.
- Let your host know that you’ve joined.
- To prevent distractions, we recommend you mute your phone. If your device does not have a mute capability – dial *6 on your keypad to mute and unmute.
After you join, you will hear everyone talking in the meeting but not see any video or content that they're sharing.
How do I use Webex with low bandwidth?
When joining from a mobile, desktop, or laptop device, a notification may apprear on the screen to let you know you have a poor internet connection. Here’s how to stay connected through bandwidth issues:
Choose voice over videoHaving your web camera on is best practice when you are working remotely, but if you have a poor internet connection - focus on maintaining your audio connectivity. From a desktop, turn your video off by clicking the camera icon. From a mobile application, select the option to switch to an audio-only meeting.
Change your audioUsing “Call Using Computer” takes up bandwidth, so try to avoid this if you have low bandwidth. Instead use the “Call Me” or “I Will Call In” options, to dial into the meeting. If you lose connectivity completely, open your meeting invitation and call one of the numbers under ‘Join by phone’.
Share content offlineIf you need to share content, send the file before your meeting or share a link to the file rather than sharing your screen. This will save valuable bandwidth so you can keep audio and video connected.
Close your applicationsClose any applications you don’t need during the meeting. This includes email, web browser tabs, file back-up services, open documents connected to cloud-based content sharing services, or applications on your desktop. This ensures your limited bandwidth is kept for real time communications during a meeting.
Turn off your VPNYour employer may have provided you with a VPN (virtual private network) service, that allows you to use the company network while working remotely. Often, this feature can limit the bandwidth available to Webex. Try turning off your VPN and see if your meeting audio, video, and screen sharing quality improves.
What if call-back isn't working?Due to high demand on local service providers for telephone services, dial-in or dial-back audio options may be unavailable to you. Here are options to stay connected:
Switch to using VOIPVoice over internet protocol (VOIP) means that your audio is sent and received using the internet. If your traditional telephone network fails, and your landline or cellular (mobile) becomes unavailable, find a wired internet, Wi-Fi or cellular data connection. Once online – you can use the ‘call using computer’ option, which allows you to join audio over the internet. We strongly recommend using a headset for the best experience.
Prioritize your bandwidth for VOIPWhen VOIP is your only option, make sure you have enough bandwidth for a clear audio experience. If you can’t hear people, or they can’t hear you, follow the advice in the "How do I use Webex with low bandwidth?" section, for advice on using Webex with low bandwidth.
