Figure  8-78: Dfining IP-to-IP Routing Rules 
 
The configured rules are summarized below: 
  Index #1: First choice route for IP Group 1 (i.e., LAN and PSTN users) when calling 
each other or any user on WAN. The call is sent to IP Group 2 (i.e., WAN IP-PBX) 
through the device's SBC interface. 
  Index #2: Alternative route for calls from IP Group 1 (LAN and PSTN users) in case of 
WAN/IP-PBX failure. This rule uses the devices internal registration database to reach 
the destination user. 
  Index #3: Second alternative route for calls from IP Group 1 (LAN and PSTN users) in 
case of WAN/IP-PBX failure and no user is registered in the database. This rule routes 
the call to the device's Gateway interface (i.e. 10.8.6.86:5070). 
  Index #4: For calls coming from IP Group 2 (i.e., WAN IP-PBX) to PSTN users. This 
rule directs all calls with destination phone number starting with "01" to the device's 
Gateway interface (i.e. 10.8.6.86:5070). 
  Index #5: All other calls from IP Group 2 are routed to IP Group 1.
