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.
- is there any document to explain this ?
