has any one had any experience working with a Sorenson VRS. it is used by deaf individuals for video conferencing and using ASL. after some time i found the way to get the forwarding to go through my core router and then through the Ubiquity CPE. i've added an edge router between there location and the core and can no longer get the ports to open up. i can get it to receive calls but unable to make calls or do outgoing video. being for a deaf couple I'm real interested in getting this to work properly.
