Session Router Configuration
219
The requirements for the Session Router can be summarized as:
•
Route ISDN data calls to the local breakout
•
Route inter-site calls to the opposite SmartNode (Node A to Node B and vice versa)
•
Route international calls to Carrier “Melon”
•
Provide a fallback for all VoIP calls on the local breakout
•
Route local calls to the local breakout
•
Route national calls to carrier “Orange”
•
Route mobile calls to carrier “Apple”
•
Calls from “local_ba”, “node_b” and “node_c” are forwarded directly to “pbx_a”
The remainder of this example will focus on the configuration for Node A. The configuration for
Node B can be built accordingly. Node C has an even simple configuration.
It is a good idea to specify the required Session Router elements and names before starting the
configuration. A sketch may be helpful:
•
Bearer Capability table named "ISDNservice", needed for requirement 1.
•
Called Party Number table named "dest_a", needed for requirement 2, 3, 6 and 7
•
CAC insertion for Apple "CACapple", needed to add Carrier Access Code for "Apple"
•
CAC insertion for Orange "CACorange", needed to add Carrier Access Code for "Orange"
•
CLI replacement for Melon "CLImelon", needed to add Carrier Access Code for "Melon"
•
PSTN interfaces "pbx_a" and "local_ba", needed for requirement 4, 5 and 8.
•
H.323 interface "node_b", needed for requirement 2.
•
ISoIP interface "node_c", needed for requirement 3.
