We have 2 School campus at different locations
We have Asterisk A2b as central DB billing it has static public IP
We have 2 OpenSip Servers, one at each school location. These Servers does not have Static Public Ip's. They are behind Firewall. Each Server are given local Ip from a wifi network at each of the school. (these Server can see outside but you cannot see them from the Net)
To Link all 3 servers we used OpenVpn sevices. So now each of the Server has 2 set of Ip's
1. A2b has a Public IP to communicate with anyone and openVpn IP to communicate with any of the OpenSip Servers.
2. Each OpenSip Server has 2 ip's. One local which sip clients use to register to it from the Wifi network. And 1 ip from OpenVpn which it use to comminicate to A2b or to route call to the other OpenSip Server.
What we want to achieve. Students can call anyone registered to any of the servers Free (at no additional internet cost to them if they register from the wifi network)
we the Company will charge small daily or weekly or periodic fees But calls are FREE to Students when they call anyone register to any of the Servers
When they make Out of Network calls then we bill as normal via rate tables
