Working Groups Dial-in & WebEx Instructions

1. Go to the email invitation that you received announcing the meeting, or go directly to WebEx: https://samsi.webex.com
2. Click on the link for the meeting you want to join
      • Enter Your Name, Your Email Address and the meeting password from the email invitation
      • The first time you use WebEx, the Meeting Manager will run and it will take about a minute to setup.
      • Now you are in the meeting and can use all the features of WebEx
3. Dial the teleconference line: 919-685-9338.
      • It is necessary to separately call into the given conference-line phone number to obtain audio interaction; we are not able to use WebEx for an audio connection. When calling in:
          o do not use a computer microphone or a speaker phone; this causes severe feedback in the system;
          o headphones and hand-held phones are fine.
      • If cost of telephone calls is an issue, consider using either Skype or JaJah to place your calls to the conference line; these are virtually free within North America, and (for example) only cost roughly 2 cents and 3 cents per minute, respectively, from Europe.
      • Please dial no earlier than 5 minutes prior to the start of the working group meeting.

Please Note: You should be seeing the screen of the presenters. If not, please send a message or call for assistance. WebEx can run slowly on Unix machines.

If you are having trouble with WebEx or the Teleconference line please contact Sue McDonald, sue@samsi.info (919)685-9359 or James Thomas, help@samsi.info (919)685-9307

You can learn more about WebEx and take tutorials at university.webex.com.
