[Asterisk-Users] Tricky setup

[Bogdan BALAJ]

Hello All,

This could be more a routing/linux problem, but I'm wondering if can be
handled somehow within *.

I have a client that has a contract with a VoIP provider. This contract
limits number of phones registered using same IP to 3. There are 3 ways to
handle this:
1. Few ATA  connected to 3 phones + network
2. Linux router that lies between * box and network. Virual interfaces,
iptables SNAT/DNAT .....
3. * properly configured connected to the network.

I looked for * configs, but I did not find a way to send traffic for
phone1-phone3 as Public_IP_1, phone4-phone6 as Public_IP_2 ...and so on.

Anyone ever did something like this using just a box?

Any ideas are welcomed.

Thank you,
Bogdan
