A.2.2 Step 2b: Configure Inbound IP Routing for PSTN Fallback
To configure IP-to-Tel or Inbound IP Routing Rules:
1. Open the Inbound IP Routing Table page (Configuration tab > VoIP > GW and IP to
IP > Routing > IP to Trunk Group Routing).
Figure 4-24: Configuring Inbound IP Routing Rules
2. The first rule in line 1 is the general rule for all incoming IP calls, with the destination
prefix assigned to a specific PBX (e.g., 832). This rule will route them to Trunk Group
ID 1 (connected to the PBX).
3. When using PSTN fallback, configure another rule (rule 2 above) for a Fallback
scenario: in the event of failure, route all outgoing calls to Trunk Group ID 4
(connected to the PSTN Fallback Trunk).
4. Click Submit to apply definitions.
Note:
In the configuration above, Trunk Group 1 is used for calls to/from BroadCloud
service, Trunk Group 4 is used to define an extra TDM PRI port for PSTN fallback if the
BroadCloud service becomes unreachable for any reason. The second route rule re-
routes traffic that failed to go out via the BroadCloud service, to Trunk Group 4.
If PSTN fallback is not used, the Trunk Group 4 route rule (second row) setting can be
discarded.
