19.2.6.1 Configuring Message Manipulations

The Message Manipulations page allows you to define up to 200 SIP message
manipulation rules. This manipulation includes insertion, removal, and/or modification of
SIP headers. Multiple manipulation rules can be configured for the same SIP message.
Once you have defined SIP message manipulation rules (Manipulation Set ID), you can
assign them to inbound and outbound SIP messages for IP Groups, using the IP Group
table.
SIP User's Manual
•
Alternative routing occurs even if this table is not configured upon
scenarios where no response, ICMP, or a SIP 408 response is received.
•
SIP requests pertaining to an SRD or IP Group that reach the call limit
(maximum concurrent calls and/or call rate) as defined in the Call
Admission table are sent to an alternative route if configured in the IP2IP
Routing table for the SRD or IP Group. If no alternative routing rule is
located, the device automatically rejects the SIP request with a SIP 486
"Busy Here" response.
•
You can also configure alternative routing reasons using the ini file table
parameter SBCAlternativeRoutingReasons.
