Step 8: Configure IP-to-IP Call Routing Rules

This step describes how to configure IP-to-IP call routing rules. These rules define the
routes for forwarding SIP messages (e.g., INVITE) received from one IP entity to another.
The E-SBC selects the rule whose configured input characteristics (e.g., IP Group) match
those of the incoming SIP message. If the input characteristics do not match the first rule in
the table, they are compared to the second rule, and so on, until a matching rule is located.
If no rule is matched, the message is rejected. The routing rules use the configured IP
Groups to denote the source and destination of the call. As configured in Section
page 35, IP Group 1 represents IP-PBX, and IP Group 2 represents BroadCloud SIP
Trunk.
For the interoperability test topology, the following IP-to-IP routing rules need to be
configured to route calls between IP-PBX (LAN) and BroadCloud SIP Trunk (WAN):

Terminate SIP OPTIONS messages on the E-SBC

Calls from IP-PBX to BroadCloud SIP Trunk

Calls from BroadCloud SIP Trunk to IP-PBX

To configure IP-to-IP routing rules:
1. Open the IP-to-IP Routing Table page (Configuration tab > VoIP menu > SBC >
Routing SBC > IP-to-IP Routing Table).
2. Configure a rule to terminate SIP OPTIONS messages received from the LAN:
a. Click Add.
b. Click the Rule tab, and then configure the parameters as follows:
