configured for any call direction (SBC, Tel-to-IP, or IP-to-Tel). Call Setup rules provide you
with full flexibility in implementing simple or complex script-like rules that can be used for
Lightweight Directory Access Protocol (LDAP) based routing as well as other advanced
routing logic requirements such as manipulation. These Call Setup rules are assigned to
routing rules.
Below is a summary of functions for which you can employ Call Setup rules:
LDAP query rules: LDAP is used by the device to query Microsoft’s Active Directory
(AD) server for specific user details for routing, for example, office extension number,
mobile number, private number, OCS (Skype for Business) address, and display
name. Call Setup rules provides full flexibility in AD-lookup configuration to suite just
about any customer deployment requirement:
• Routing based on query results.
• Queries based on any AD attribute.
• Queries based on any attribute value (alphanumeric), including the use of the
asterisk (*) wildcard as well as the source number, destination number, redirect
number, and SBC SIP messages. For example, the following Call Setup rule
queries the attribute "proxyAddresses" for the record value "WOW:" followed by
source number: "proxyAddresses=WOW:12345*"
• Conditional LDAP queries, for example, where the query is based on two
attributes (&(telephoneNumber=4064)(company=ABC)).
• Conditions for checking LDAP query results.
• Manipulation of call parameters such as source number, destination number, and
redirect number and SBC SIP messages, while using LDAP query results.
• Multiple LDAP queries.
Dial Plan queries: For SBC calls, you can use Call Setup rules to query the Dial Plan
table (see Configuring Dial Plans on page
751) for a specified search key in a
specified Dial Plan to obtain the corresponding Dial Plan tag. Call Setup rules can also
change (modify) the name of the obtained tag. The device can then route the call
using an IP-to-IP Routing rule (in the IP-to-IP Routing table) that has a matching tag
(source or destination). You can also associate a Call Setup rule with an IP Group (in
the IP Group table). Once the device classifies the incoming call to a source IP Group,
it processes the associated Call Setup rule and then uses the resultant tag to locate a
matching IP-to-IP Routing rule. You can also use Call Setup rules for complex routing
schemes by using multiple Dial Plan tags. This is typically required when the source
and/or destination of the call needs to be categorized with more than one
characteristics. For example, tags can be used to categorize calls by department
(source user) within a company, where only certain departments are allowed to place
international calls.
Manipulation (similar to the Message Manipulations table) of call parameters (such as
source number, destination number, and redirect number) and SBC SIP messages.
Conditions for routing, for example, if the source number equals a specific value, then
use the call routing rule.
You configure multiple Call Setup rules and group them using a Set ID. This lets you apply
multiple Call Setup rules on the same call setup dialog. To use your Call Setup rule(s), you
need to assign the Set ID to one of the following using the 'Call Setup Rules Set ID' field:
SBC IP-to-IP routing - see Configuring SBC IP-to-IP Routing Rules on page 709
Tel-to-IP routing rules - see Configuring Tel-to-IP Routing Rules on page 525
IP-to-Tel routing rules - see Configuring IP-to-Tel Routing Rules on page 534
IP Groups - see Configuring IP Groups on page 365
If assigned to an IP Group, the device processes the Call Setup rule for the classified
source IP Group immediately before the routing process. If assigned to a routing rule only,
the device first locates a matching routing rule for the incoming call, processes the
