  • Click on the meeting you want to join.

  • Enter Your Name, Your Email Address and the meeting password from the email.
    1. The first time meeting manager will run and it will take about a minute to setup.

    2. Now you are in the meeting and can use all the features of WebEx.

    3. Make sure you are seeing the screen of the presenters, if not send a message or tell via phone.

    4. You can learn more about WebEx and take tutorials at university.webex.com and login a guest.

    5. WebEx URL is samsi.webex.com

    6. Note: WebEx can run slowly on Unix machines.

Teleconference Line

  • 919-685-9338

  • Please dial no earlier than 5 minutes prior to working group meeting.
If you are having trouble with WebEx or the Teleconference line please call (919)685-9350.

Note: Until we can get the needed bandwidth, equipment, etc. for broadcasting meetings via a webcam, SAMSI will be employing the following process for remote participation in working groups. A webcam picture will be available for viewing during the meetings. However, for audio, participants will have to call into the conference line.
