22.2 Configuring Message Condition Rules
The Message Conditions table lets you configure up to 82 Message Condition rules. A
Message Condition defines special conditions (requisites) for incoming SIP messages.
These rules can be used as additional matching criteria for the following:

Classification rules in the Classification table (see Configuring Classification Rules on
page 663)

IP-to-IP routing rules in the IP-to-IP Routing table (see Configuring SBC IP-to-IP
Routing Rules on page 671)

Outbound Manipulation rules in the Outbound Manipulations table (see Configuring IP-
to-IP Outbound Manipulations on page 705)
Message Condition rules are configured using the same syntax as that used for Conditions
when configuring Message Manipulation rules in the Message Manipulations table (see
Configuring SIP Message Manipulation on page 381). You can configure simple Message
Condition rules, for example, "header.to.host contains company", meaning SIP messages
whose To header has a host part containing the string "company". You can configure
complex rules using the "AND" or "OR" Boolean operands and also use regular
expressions (regex), for example:

"body.sdp regex pcmu" can be used to enable routing based on the offered codec
(G.711 Mu) in the incoming SDP message.

"body.sdp regex (AVP[0-9||\s]*\s8[\s||\n])" can be used to enable routing based on
payload type 8 in the incoming SDP message.
Note: For a description on SIP message manipulation syntax, refer to the SIP
Message Manipulations Quick Reference Guide.
The following procedure describes how to configure Message Condition rules through the
Web interface. You can also configure it through ini file (ConditionTable) or CLI (configure
voip > sbc routing condition-table).
