Hello Everyone!
So currently we have 2 locations, and the VOIP system is interconnected via a T-1 With MPLS. QoS is configured at both gateway routers at each location to prioritize the VLAN the VOIP network is segmented on. (10.1.2.0/24) Now at our main location, we're swapping the T-1 for fiber and getting an entirely new VOIP system. The other location needs to be patched and connected to access the new system until we can replace it. I was thinking a VPN concentrator at location 2 would do the trick, and then just set up QoS at the router level for both locations and that way we shouldn't have any noticeable call degradation. Any ideas on how I'm gonna make this work?
