|Im wondering if I have to set anything up at the location with the QOS and Voip configs and add anything to the firewall and at the other location add all the ACL's. |
You shouldn't have to set up anything for QoS since that's controlled on the switches. Unless you want your firewall to do QoS and it's QoS capable.
The VoIP I'm not sure, you might have to make a firewall rule to allow the traffic to pass in and out of your network.
As for the ACL's on the software firewall it seems to me you might want to replicate them on the new firewall since you're not going to want two firewalls so you should be replacing the existing software one.
I'm not familiar with Cisco firewalls, we used teamed (redundant) OpenBSD firewalls/routers where I work.
