We have several PPPoE servers at different sites (rb750) where ether1 is connected to the customers and has the server running on it obviously.
Ether2 is connected back to our licenced link (ceragon) which tunnels the traffic back to the edge.
I was interested in using the TDM port on the ceragon IDU for the VOIP traffic only. Is it possibble for the PPPoE server to pick up on a VOIP call and tunnel the VOIP traffic down the TDM port via Ether3 on the rb750? Our VOIP provider only has a /24 so we could easily add this to the firewall if needs be.
