I have a CCM 3.3 at HQ,with trunk ports on the PABXs connected to the router at branches on FXS ports.The CCM IP is 192.168.1.48 and can be pinged from both branches.HQ is on a 1XXX dial plan,to call branch A(192.168.21.1) u use 2000 or 2001 and Branch B(192.168.22.1) 3000 and 3001.I have ONLY configured the pots and voip dial peers,what more configuration do i need for the CCM at HQ to see both routers as gateway or is thea any other way the configuration is done....
