   It may do the job, and well. It would mean that the VoIP and ethernet are
entirely separate, the kind of approach taken by Solwise. I have seen a
cautionary note about firewalls and NAT. This could be a big problem, or is
it one that is easily circumvented? Does it require an IP block, or can it
be made to work with a single IP address? The people who want the system are
making large numbers of expensive international calls.
