We are installing a Voip solution and i'm confused what exactly is required in terms of getting the voice traffic to work reliably.
Concerns are around the type of switches used firstly. Can someone confirm if layer 2 or 3 is required for the voice only? Then i need to know details in order to connect the 2x sites together, taking into account that we do not have a dhcp server (microsoft one) @ our remote site.
Attached is our current network, along with additional components (not yet installed & configured)
VLAN 10 switches
ISDN2 on the v90 BRI's
We will dedicate switches for voice and data for redundancy.
I have been told we can prioritize the traffic on the firewall/router. But reading in more detail this is also managed by the switch. COrrect?
