LAB 8B: UC520 Multi-site Setup
LAB 8B: UC520 Multi-Site Setup
Introduction:
SBCS & UC520 can support a deployment where you network multiple sites together. The maximum
number of sites that can be networked is 5 at this time. In a typical multi site deployment, the
requirement is to have IPSec VPNs between each site and also setup site to site dialing via 4 or 5 digits.
This also supports transfer and conference of calls between sites – since this is a distributed call
processing setup, you cannot have a centralized directory and AA for all sites.
Objective:
The main objective of this lab is to configure the basic PBX system, voicemail and Auto Attendant
features and then network the UC520s together to support inter site dialing. These features will be
configured using Cisco Configuration Assistant (CCA) and command line interface (CLI). After
completion of this lab – you will be able to setup the SBCS system in a multi site deployment and call
between sites and the PSTN. This lab will not go over the IPSec VPN setup.
Note: Lab 8a is the IPSEC VPN configuration lab. However, that configuration is NOT necessary
for this Multi-Site configuration lab because the UC520’s are already on a private network
connection (directly connected).
Topology:
Setup steps:
1. This lab requires you to work with your “buddy” POD. It also assumes that both PODs have
been reset to factory defaults. Follow steps 2 – 10 for both PODs – this is the same as you had
done for LAB 2 so should be a repeat and simple to complete.
2. Launch CCA, connect to the created community and enter the username and password
(cisco/cisco) and let it discover the network and connected devices.
3. Check the topology to ensure all the connected phones are showing up.
