4.4.3 To call into an NRAO video system via the ISDN Gateway

The following are instructions that you should give to outside sites if they will dial into the NRAO over ISDN to initiate a video conference.

1. The available ISDN Phone Numbers are:
   434-296-0386/7
   434-296-0388/9
   434-296-0392/3

2. An Interactive Voice Response system answers. At the voice prompt, enter a number from the following selection:
   
   For multi-point calls (several NRAO sites will be connected):
   Hub number: 601234#
   
   For point-to-Point Calls:
   CV via the Gateway: 46652#
   GB via the Gateway: 46699#
   SO via the Gateway: 46678#
   TU via the Gateway: 35750#
   

Note: the Gateway should default to connecting the caller to the NRAO video hub if the caller does not enter anything. Some video phone systems may not be able to entering further numbers at the IVR prompt, and these systems will always connect to the hub. Any NRAO users who wish to conference with incoming ISDN calls from such systems should therefore also connect to the NRAO video hub, even for a point-to-point meeting.
