Using Dial Plan Tags for Call Setup Rules
You can use Dial Plan tags in Call Setup rules, configured in the Call Setup Rules table (see
Configuring Call Setup Rules ). The Call Setup rule can be assigned to an IP Group and is
processed by the device for the classified source IP Group immediately before the routing process
(i.e., Classification > Manipulation > Dial Plan table > Call Setup rules > Routing). The result of the
Call Setup rule (i.e., source and/or destination tag) can be used as the matching characteristics for
locating a suitable IP-to-IP Routing rule in the IP-to-IP Routing table.
You can configure Call Setup rules to query the Dial Plan table for a specified key (prefix) in a
specified Dial Plan to obtain the corresponding tag. The Call Setup rule can then perform many
different manipulations (based on Message Manipulation syntax), including modifying the name of
the tag. The tags can be used only in the 'Condition', 'Action Subject' and 'Action Value' fields.
Using Dial Plan Tags for Message Manipulation
You can use Dial Plan tags ( srctags and dsttags ) in Message Manipulation rules, configured in the
Message Manipulations table (see Configuring SIP Message Manipulation ). The tags can be used
only in the 'Condition' and 'Action Value' fields. For example, you can configure a rule that adds the
SIP header "City" with the value "ny" (i.e., City: ny) to all outgoing SIP INVITE messages
associated with the source tag "ny":
Dial Plan tags cannot be modified using Message Manipulation rules.
