How would one connect with more than just two participating sites?

This FAQ was last modified on: Tuesday, January 16, 2018 05:38pm

There are two methods for connecting more than two endpoints in a conference: Multisite and Multipoint.


Most late model room-based endpoints can be fitted with a “Multisite” feature, which allows calls to multiple endpoints to be made and bridged directly by the originating endpoint – where multiple unicast streams are serviced by the endpoint.

For the majority of Multisite fitted endpoints, a total of 4 endpoints may join in a given call, including the originating endpoint that is hosting the bridged call.

What types of VTC testing resources are available?

This FAQ was last modified on: Tuesday, January 16, 2018 05:34pm

Videoconferencing endpoints that are associated to the GT VTC Service can dial VTC Test Sites that have been populated into the Address Book as static entries. These test inside network and outside network connectivity as well as routing. If the endpoint can successfully connect to these sites, it is working correctly.

Always check the phone book for the most up to date test sites, but a list of test sites is below:

Can computer content be shared in a video conference?

This FAQ was last modified on: Tuesday, January 16, 2018 09:25pm

Most standards based video conferencing systems are capable of sharing computer content within the call using the ITU H.239 standard for H.323 or BFCP for SIP. This is known by different names depending on the manufacturer, but the two most common are Duo Video (on Cisco and Tandberg endpoints) or People + Content (on Polycom endpoints.) Typically these are options which may or may not have been purchased when the endpoint was procured. Endpoints with the option fitted can share their content with other participants.

What if a service (such as ISDN connectivity, conference recording, etc) is needed but not provided under the scope of the GT VTC service?

For several years Georgia Tech Professional Education has maintained a diverse infrastructure to support distance learning programs using video conferencing. Additional services may be available on a fee for service basis.

What do I do if I am told I need a Polycom to attend a video conference, but I have a Cisco system?

This FAQ was last modified on: Tuesday, January 16, 2018 09:44pm

Cisco, Tandberg, Polycom and Life Size are all brand names of equipment. This is much like referring to all facial tissue as Kleenex or all photocopiers as Xerox machines. As long as all the devices are standards compliant (H.323 or SIP), they should work together.
