Section 5: Voice (7 Points)
Configure VoIP between R1 and R4 using the numbers supplied in Figure 3-10; ensure your VoIP is operational if the Frame Relay network fails.
Set up a hunt group on R4 so that if the number 01189 is dialed and voice port 1/1/0 is in use, port 1/1/1 answers the call. Port 1/1/0 should always answer the call if the phone connected to this port is not in use first.
Define an order of preference for selecting a codec when R1 initiates a call to R4. R1 should first negotiate to use a g728 codec and then fall back to a g729r8 with a 20-byte payload. Leave the R4 codec as default.
