3cx and several nics

[funnycoder]

Hello, we started using 3pbx several weeks ago. It works perfect, but we have one question.
We have 3 pbx windows server with 4 nics.
How can we configer outbound calls to be routed through a cdifferent nics.
For example.
3 pbx nic one - 192.168.0.10
3pbx nic two - 192.168.0.11
3pbx nic three - 192.168.0.12
3pbx nic four - 192.168.0.13

We need :
User 1 outgoing calls should be made throug nic one
User 2 outgoing calls should be made throug nic two
User 3 - nic three
User 4 - nic four

By the way - the operator is same for the all user, so adding static route to operators ip address can not be a solution.

Thanks a lot for any help!

I am not sure I understand the question. It seems that you have 3 different servers running 3CX and between the 3 servers there are 4 NICs? "We have 3 pbx windows server with 4 nics."

Can your provide more detail?

I think he meant a 3cx server with 4 nics. what would be the point of using a different nic for each user?
3cx has trouble with more than 1 nic - I do not recommend it.

3CX can work quite well with 2 NICs when one is public and one is private, but to have 4 NICs on the same private subnet is quite ridicoulus.
Assuming that they all run at 100Mbps ONLY, each card can handlye about 1500 concurrent phone calls (w G711). I think you will need to review your architecure a bit.

We have run into several problems where multiple NIC's are involved on a 3CX server. Remember that SIP header info has to determine routing & endpoints, so multi-NIC's just make this confusing. Where I had 2 NIC's on a server, I had to disable one to get consistent call connection & quality.
Keep it simple ...
