UC520 in multible Sites

Unanswered Question
Jan 16th, 2010


I have a customer who has three sites , I'm going to implement a UC520 system in each site, the connectivity between the branches are there over VPN tunnels. my questions are:

  • can you provide a document for the configuration of the UC520 in multible sites to make them able to communicate with each other.
  • how can I calculate the number of calls that can be made between each two branches ?
I have this problem too.

You will find a document on Multisite and CAC/Traffic Shaping here:


My advise is read adn understand them, then plan your design, then stage it in your own lab to make sure you know how to make it work, before deploying.

CCA 2.2.1 should be used to set this up (the latest release) and do undersand you need unique DATA VLAN subnets at each site.
