User's Manual 25. Routing
Advice of Charge (AOC): AOC is a pre-billing feature that tasks the rating engine
with calculating the cost of using a service (Tel-to-IP call) and relaying that information
to the customer. AOC, which is configured in the Charge Codes table, can be applied
per Tel-to-IP routing rule.
Notes:
• You can configure up to three alternative routing rules per "main" routing rule in
the Tel-to-IP Routing table.
• By default, the device applies telephone number manipulation (if configured) only
after processing the routing rule. You can change this and apply number
manipulation before processing the routing rule (see the RouteModeTel2IP
parameter).
The following procedure describes how to configure Tel-to-IP routing rules through the
Web interface. You can also configure it through ini file (Prefix).
To configure Tel-to-IP routing rules:
1. Open the Tel-to-IP Routing table (Configuration tab > VoIP menu > GW and IP to IP
> Routing > Tel to IP Routing).
2. Click Add; the following dialog box appears:
Figure 25-3: Tel-to-IP Routing Table - Add Row Dialog Box
3. Configure a routing rule according to the parameters described in the table below.
4. Click Add.
The following table shows configuration examples of Tel-to-IP routing rules, where:
Rules 1 and 2 (Least Cost Routing): For both rules, the called (destination) phone
number prefix is 10, the caller's (source) phone number prefix is 100, and the call is
assigned IP Profile "ABC". However, Rule 1 is assigned a cheaper Cost Group than
Rule 2, and therefore, the call is sent to the destination IP address (10.33.45.63)
associated with Rule 1.
Rule 3 (IP Group destination): For all callers (*), if the called phone number prefix is
20, the call is sent to IP Group "ITSP-ZA".
Rule 4 (domain name destination): For called phone number prefixes 5, 7, 8, or 9,
and the caller belongs to Trunk Group ID 4, the call is sent to the domain "itsp.com".
Rule 5 (block): For all callers (*), if the called phone number prefix is 00, the call is
