We currently have Tandberg video conferencing units that we use for internal video conferencing. However we need to be able to video conference with other people on the internet. I have been reading about using a 2621xm router as a gateway to do this. I have not found any configuration examples of this, and I am not sure if that is the only piece I need for the internet video conferencing. Can somebody tell me if this is correct or point me in the right direction.
