Setting Up Cisco IP PBX
This KB will explorer setting up a Cisco IP PBX for PRI traffic to Phones.
For the purpose of this document, you have a Cisco IP PBX that is separate from your primary router for any number of reasons. The Cisco IP PBX is not responsible for anything accept DHCP, routing calls, and Storing Voicemail.
You will need two separate VLANs established on your switch, one for DATA traffic (routable outside your local IP Scheme) and a separate VLAN for only voice traffic. For the sake of this, VLAN 1 is DATA, VLAN 10 is VOICE.
