Voip phones will not work on the network. Currently using WRT54G as the DHCP server for the network. Do I need to open any ports or change
any settings that I would not have changed by setting up DHCP? This is
one of the original WRT54G's with the older 1.0x Firmware. Would upgrading to 3.0 or higher fix the problem or do I need to run third party Firmware to get Voip phones to work. Thanks.
