We have a BCM50 r2 with three VOIP sets connected through a Netgear Router with Cox as the data provider. Cox has issued a Static address through thier modem and the Computer vendor set up a NAT through the Netgear sending the Static address to the Netgear as 192.168.1.150 that connects to the BCM 50. All phones connect but thety cannot hear incoming or outgoing. They have allowed port 7000 thourgh the router and 28000 to 28255 and 20000 to 20255. Anyone know if the problem is the router or the BCM.
