User's Manual 20. IP-to-IP Routing Application
• 'Source IP Group ID': enter "4" to assign these calls to the IP Group pertaining to
the remote IP-PBX users.
7. Index #6: is used for alternative routing. This configuration identifies all IP calls
received from the IP-PBX and which can't reach the ITSP's servers (e.g. loss of
connection with ITSP's) and routes them to the local PSTN network:
• 'Dest Phone Prefix': enter the asterisk (*) symbol to indicate all destinations.
• 'Source IP Address': enter the IP address of the IP-PBX (i.e., 10.15.4.211).
• 'Trunk Group ID': enter "1" to route these calls to the Trunk Group ID configured
for the Trunk connected to the device and interfacing with the local PSTN.
• 'Source IP Group ID': enter "-1" to indicate that these calls are not assigned to
any source IP Group.
20.2.9 Step 9: Configure Outbound IP Routing
This step defines how to configure the device for routing outbound (i.e., sent) IP-to-IP calls.
In our example scenario, calls from both ITSP's must be routed to the IP-PBX, while
outgoing calls from IP-PBX users must be routed according to destination. If the calls are
destined to the Japanese market, then they are routed to ITSP-B; for all other destinations,
the calls are routed to ITSP-A. This configuration uses the IP Groups defined in 'Step 5:
Configure the IP Groups' on page 254 and IP Profiles defined in 'Step 7: Configure IP
Profiles for Voice Coders' on page 256.
 To configure outbound IP routing rules:
1. Open the Outbound IP Routing Table page (Configuration tab > VoIP menu > GW
and IP to IP > Routing > Tel to IP Routing).
2. Configure Index #1 to route IP calls received from ITSP-A to the IP-PBX:
• 'Source IP Group ID': select 1 to indicate received (inbound) calls identified as
belonging to the IP Group configured for ITSP-A.
• 'Dest Phone Prefix' and 'Source Phone Prefix' : enter the asterisk (*) symbol to
indicate all destinations and callers respectively.
• 'Dest IP Group ID': select 3 to indicate the destination IP Group to where these
calls are sent, i.e., to the IP-PBX.
• 'IP Profile ID': enter "2" to indicate the IP Profile configured for G.723.
3. Configure Index #2 to route IP calls received from ITSP-B to the IP-PBX:
• 'Source IP Group ID': select 2 to indicate received (inbound) calls identified as
belonging to the IP Group configured for ITSP-B.
• 'Dest Phone Prefix' and 'Source Phone Prefix': enter the asterisk (*) symbol to
indicate all destinations and callers respectively.
• 'Dest IP Group ID': select 3 to indicate the destination IP Group to where these
calls are sent, i.e., to the IP-PBX.
• 'IP Profile ID': enter "2" to indicate the IP Profile configured for G.723.
4. Configure Index #3 to route calls received from the local PSTN network to the IP-PBX:
• 'Source Trunk Group ID': enter "1" to indicate calls received on the trunk
connecting the device to the local PSTN network.
• 'Dest IP Group ID': select 3 to indicate the destination IP Group to where the calls
must be sent, i.e., to the IP-PBX.
5. Configure Index #4 to route IP calls received from the IP-PBX to ITSP-A:
• 'Source IP Group ID': select 3 to indicate received (inbound) calls identified as
belonging to the IP Group configured for the IP-PBX.
• 'Dest Phone Prefix': enter "+81" to indicate calls to Japan (i.e., with prefix +81).
