5.1.12 Step 9: Routing Setup
The Media Gateway's IP-to-IP call routing capabilities is performed in two stages:
1.
Inbound IP Routing:
Recognizes the received call as an IP-to-IP call or IP-to-Tel call based
on the call's source IP address or/and Dest. Phone Prefix and /or the Source Phone Prefix.
This stage is configured in the ‘IP To Trunk Group 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 stage is configured in
the ‘Tel to IP Routing Table'.
5.1.13 Step 9-a: Configure Inbound IP Routing
This step defines how to configure the Media Gateway’s IP to Trunk Group Routing Table.

2.
Configure the following routing rules:
•
Row 1
– calls from source IP address 192.168.0.4 (i.e., ATA 1) are assigned to Trunk
Group ID '-1', identifying them as inbound IP-to-IP calls. These calls are later routed to
the Mediation Server (Section
).
•
Row 2
- calls from source IP address 192.168.0.5 (i.e., ATA 2) are assigned to Trunk
Group ID '-1', identifying them as inbound IP-to-IP calls. These calls are later routed to
the Mediation Server (Section
).
•
Row 3
– calls from IP address 192.168.0.1 (i.e. Mediation Server) and the destination
number prefix is +1732652100 (i.e. one of the embedded Media Gateway FXS ports) are
routed to Trunk Group ID 1 (configured in Section
).
•
Row 4
– calls from IP address 192.168.0.1 (i.e. Mediation Server) and the destination
number prefix is +1732652200 (i.e. one external ATA devices) are assigned to Trunk
Group ID '-1', identifying them as inbound IP-to-IP calls. These calls are also assigned to
the IP Group pertaining to Mediation Server (configured in Section
•
Row 5
– all other calls (that do not match any of the above rules) are routed to Trunk
Group ID 2 (i.e., the PSTN).
