8.4.10.3.4 Step 4: Define IP-to-IP Routing Rules
The procedure below describes how to configure IP-to-IP routing rules. The following rules
need to be included in the configuration:
Existing rules:
• Routing from LAN users to IP-PBX (i.e., from IP Group 1 to IP Group 2), as
previously defined in ''Step 9: Define IP-to-IP Routing Rules'' on page 555
• Alternative routing between LAN users
in case of WAN or IP-PBX failure, as
previously defined in ''Survivability and Alternative Routing'' on page 556
• Routing from
IP-PBX to LAN users (i.e., from IP Group 2 to IP Group 1), as
previously defined in ''Step 9: Define IP-to-IP Routing Rules'' on page 555
Ne
w rules to add:
• Alternative routing to PSTN for LAN users in case of WAN or IP-PBX failure (this
is the secondary alternative route if the user is not registered in the device's user
registration database)
• Routing for calls destined to PSTN network
¾ To configure IP-to-IP routing rules:
1. Open the 'IP2IP Routing Table' page (Configuration tab > VoIP menu > SBC
submenu > Routing SBC submenu > IP to IP Routing Table).
2. Add a secondary alternative IP-to-IP routing rule (Index #3) for routing LAN user calls
to PSTN upon WAN/IP-PBX failure:
a. In the 'Add' field, enter 3, and then click Add; the new entry is added as Index #3
after Index #2. The previous Index #3 is now shifted down to Index #4.
b. From the 'Source IP Group ID' drop-down list, select '1'. This is the IP Group to
which the LAN users belong.
c. From the 'Destination Type' drop-down list, select 'Dest Address' and then in the
'Destination Address' field, enter the IP address 10.8.6.86 (i.e, the IP address of
the device's LAN gateway interface).
d. In the 'Destination Port' field, enter port number 5070.
e. From the 'Alternative Route Options' drop-down list, select 'Alt Route Consider
Inputs'.
f. Click Apply.
3. Add an IP-to-IP routing rule (Index #4) for routing calls destined to the PSTN network:
a. From the 'Source IP Group ID' drop-down list, select '2'. This is the IP Group to
which the WAN IP-PBX belongs.
b. In the 'Destination Username Prefix', enter 01. This represents calls destined for
the PSTN. (You can change this according to your PSTN numbering plan.)
c. From the 'Destination Type' drop-down list, select 'Dest Address', and then in the
'Destination Address' field, enter the IP address 10.8.6.86 (i.e, the IP address of
the device's LAN gateway interface).
d. In the 'Destination Port' field, enter port number 5070.
