Configure A2billing and OpenSips as follow:
A2billing is Central Billing Server and will handle all user info for multiple OpenSips Servers located at different places. Since some or most of these OpenSip Servers are behind Nat, OpenVpn will be installed in all these Servers. We already have the OpenVpn tunnel configured so any newly added Server will get a OpenVpn IP that it can use to communicate with the rest and with A2billig.
At each location, local Lan users will register to the local OpenSip Server , however user info and billing will come from the centrally located A2billing MySql Server (or Cluster of 2 for redundancy incase one goes down)
Note: Local lan users cannot see A2billing Server because they are behind Nat. All communications , or calls between OpenSip Servers will go through OpenVpn tunnel.
All Calls within each local Lan users will be routed within that OpenSip Server .
For Now only 1 A2billing Server and 1 OpenSip Server will be configured. However we need the config in a file so we can use it as additional OpenSip Servers are added. We will add extral cash for this.
Only serious knowledgeable Asterisk/Opensip guys should bid
