Series of ports are blocked
Our VoIP system utilizes a series of ports between 9000 and 11000. Static IPs have been installed and the modem firewalls have been disabled. However testing continues to fail on the ports between those ranges. A couple of calls for T2 support continue to state that there are no blocked ports, however our internal testing and the inconsistent behavior of our VoIP system says otherwise. Is there any other area that may be blocking traffic to these ports?
