5.8  Step 9: Configure IP-to-IP Routing Setup 
The E-SBC devices’ IP-to-IP call routing capability is performed in two stages: 
1.  Inbound IP Routing: Recognizes the received call as an IP-to-IP call, based on 
the call's source IP address. This step is configured in the 'Inbound IP Routing 
Table'  
2.  Outbound IP Routing: Once recognized as an IP-to-IP call in the first stage (see 
above), the call is routed to the appropriate destination (i.e., IP address). This step 
is configured in the 'Outbound IP Routing Table'. 
5.8.1  Configure Inbound IP Routing 
This step defines how to configure the E-SBC device for routing inbound (i.e., 
received) IP-to-IP calls. Figure 
 5-21 illustrates three different call scenarios, 
corresponding to Index #1, Index #2 and Index#3 (described below). 
¾  To configure inbound IP routing: 
1.  Open the 'Inbound IP Routing Table' page (Configuration tab > VoIP menu > 
GW and IP to IP > Routing submenu > IP to Trunk Group Routing).
