We are getting ready to implement new voice connection and we will be implementing IP2IP gateways.
The connection will be DS3s to a 3845, then to another 3845 that will be an IP2IP gateway router.
What is the usual connection from Provider to the edge router,
Edge router to IP2IP Gateway router,
IP2IP GW to Call Manager?
The IP2IP gateway routers have two gigabit ethernet ports.
Would it be best practice to have one etherent interface on the IP2IP router on a seperate subnet and interface with the Edge router and have the other IP2IP ethernet interface on a different subnet as the Call Manager?
Or have the Edge router LAN interface and IP2IP router on the same subnet as Call Manager?
