I setup an IP6000 to connect to a Toshiba CIX Phone System. I setup in my own office and tested to client's headoffice and all tested fine. Once I shipped to Client's remote location calls would connect but there was no audio(both ways). Reset unit, changed audio codec, no change. The Client has a Actiontech Router, I am trying to help their IT dept troubleshoot this issue. Is there any port that should be forwarded to the IP6000?
Thanks for your input!
