Vlan for voice and vlan for data with diferent ISP best choice of config??

[oortizvi1]

Hello everyone,

Im, Oscar

At our company we have a redundant ISP connection to two separate ISP's.

We are also using VoIP on the network.

Currently one ISP connection is used primarily and the second on is just used as a backup.

I was wondering if it is possible to use the first connection primarily for data traffic and the second connection for VoIP traffic?

We use different VLAN's for voice and data.

Any help would be appreciated.

Yes, for egress.  Ingress is "it depends".

You could also consider using both links for both kinds of traffic.

If you're using NAT, return traffic will come back on the NAT'ed interface.
