I am setting up a firewall that has bandwidth management capabilities.  In order to provide the phones with enough bandwidth, how much should I allocate for 5 phone lines using G711 codec?  I searched EE, but there are some conflicting answers regarding just the pure bandwidth consumed and the calls including header information.  Thanks for your advice.

would that be plenty?  I'm guessing that that number is both up and down speeds?
Correct. If you have enough bandwidth, just slot out 1Mb. If you have your QoS right, then it will only take effect when your VoIP requires it. Otherwise, that bandwidth is available for data.

You also need to consider that 436k is for 5 simultaneous calls. Usually there will only be one or two people on the phone at a time...
