Has anyone ever integrated a Polycom KIRK wireless system with a Toshiba CIX 670? The system consists of a Polycom IP6000 server, 2 Base Stations, and 4 repeaters with 6 KIRK 5020 handsets. The Toshiba has 2 MIPU cards of course and SIP stations built in it. I have talked to Toshiba but the person I talked to didn't seem to know much about it. The person I have been dealing with at Polycom possibly doesn't know what he is doing either. Go figure. He has looked at the Trace Routes from the IP6000 and says that the Toshiba is rejecting the attempts to connect from the IP6000. I quote from Polycom, "Your SIP server(CIX 670) is responding with "403 Forbidden" and "404 Not Found" messages". Can anyone help?
