Configuring Message Condition Rules - AudioCodes Mediant 800B User Manual

User's Manual
1. In the Classification table, add the following classification rules:
Source Username
Index
Prefix
0 333
1 1111
2. In the IP Groups table, add the following IP Groups:
Index
1
2
In the example, a match exists only for Classification Rule #1. This is because the source
(1111) and destination (2000) username prefixes match those in the INVITE's P-Called-
Party-ID
"<sip:2000@10.10.10.10.10>"), respectively. These SIP headers were determined in IP
Group 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 657)

IP-to-IP routing rules in the IP-to-IP Routing table (see 'Configuring SBC IP-to-IP
Routing Rules' on page 666)

Outbound Manipulation rules in the Outbound Manipulations table (see 'Configuring
IP-to-IP Outbound Manipulations' on page 691)
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 378). 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:
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).
