I'm implementing a UC520 system for three branches, in my scenario I have three UC520 system in each branch and the three branches and connected Via VPN tunnel created in a 2800 series router in each site (SO from each site I can ping and access any device at the other sites). I need now to connect the voice between the branches so I want to clear some points before starting the configuration:
Since the VPN sonfigurtion is done on the router not on the UC520 then can I use the Mulisite manager or not ? and if not then will I be able to use the features on the Uc520 such as (Call admision control, traffic shaping, number of calles).
what is the best configuration or solution to make this three site comunicate together as a voice.
