Troubleshooting for GoToMeeting on video conference systems

This article covers open, known issues and lists possible problems and the likely solutions by topic.


  • Room echo or feedback
  • Mute audio for all but one device in a conference room. For example, if there are two attendees joined over their laptops in the conference room in addition to the system attendee, mute the system attendee and one of the laptops.

Firewall configuration

  • Call does not connect
  • Call connects but disconnects after a timeout
  • Call connects but media is blocked (usually inbound media)

Verify the system configuration is correct.

  • Some firewalls have limited built-in H.323 support may not work with our solution
  • Some firewalls have very low (< 30sec) idle timeouts.

Customer gatekeeper configuration

A gatekeeper provides address translation, admissions control, call routing, authorization and accounting services to an H.323 system.

GoToMeeting Gatekeeper IP address:

  • Call connects but there is no audio and/or video
  • Call connects but audio and/or video freezes intermittently
Issue analysis

To figure out if the problems are caused by a misconfigured gatekeeper, do the following.

  • Try to not register with the gatekeeper
  • Try registering with GetGo gatekeeper

Setup GNU Gatekeeper (GnuGk).
