most DHCP servers (at least the ISC and the microsoft ones) allow you to
statically distribute IP:

you can configure the software to give:
ip adress "ip1" to the host with the ethernet address "mac1"
ip adress "ip2" to the host with the ethernet address "mac2"
ip adress "ip3" to the host with the ethernet address "mac3"

"ip1" will be systematicely assigned to the host with the ethernet address
"mac1"
"ip2" ....................................................................
"mac2"
etc..

this way some part or every host on your LAN will have static addresses
while being DHCP clients.

works wonderfully.

there is some application-level proxy which supports netmeeting (and a lot
of programs that use H.323 protocol)

http://www.equival.com/phonepatch/

i didn't test it.

it should allow outgoing and incoming calls from/to your PCs, it works like
a PABX.

if you just want to allow outgoing calls, i think you could use NAT.
