NIC A for telephony and NIC B for LAN ?

[scenarist]

I have two network cards
NIC A (It will be used for IP telephony only)
(I connect LAN cable from optical converter of my provider direct to NIC A of goautodial)
IP: 217.75.xxx.xxx
SUB: 255.255.255.192
G: 217.75.xxx.xxx

NIC B (It will be used for internet and LAN for my agents )
(LAN cables from my router to goautodial in NIC B and agents)
IP: 192.168.1.2 till 254
SUB: 255.255.255.0
G: 192.168.1.1 (my router)

All telephony traffic it will goes through NIC A , and I registered sip trunk via IP authentication.

Agents will login via browser and 192.168.1.2 (ip address of goautodial)

Is this possible configuration ? Please give me some advice ?

Do I need setup some other configuration (iptables) to forward traffic from 217.75.xxx.xxx to 192.168.1.xx(agents) or above configuration is enough ?

P.S
My telephony provider using one IP for telephony and another IP for internet , because that I must setup above configuration

I recommend you use one for "external" and one for "internal" instead of telephony vs "everything else". Much simpler setup.

Your vicidial system uses NIC A for Internet. Your agents access the server through the local IP address on NIC B. And your agents access the internet through the router that's on the same network as NIC B. (Not in any way related to Vicidial).

Not much to configure at all, if you merely remember to give NIC A an internet Gateway and don't give NIC B one.
