SIP Header Manipulation

SIP header manipulation allows you to add, delete, or modify SIP message attributes on the Oracle Enterprise Communications Broker (OECB). For example, SIP headers and SIP header elements.

The most common reason for manipulating SIP headers and SIP header elements is to fix an incompatibility problem between two SIP endpoints. For example, Softswitch - PSTN incompatibility or a SIP messaging problem between two different IP PBX platforms in a multi-site deployment where calls between the platforms are unsuccessful due to problems in the SIP messaging.

To enable the SIP header manipulation, create rule sets in which you specify header manipulation rules and, optionally, header element manipulation rules. SIP header elements are the sub-parts of the header, such as the header value, the header parameter, the URI parameter, and so on, excluding the header name. You can specify the actions that you want the system to perform for each header element.

After creating the header manipulation rule set, apply it to a session agent or SIP interface as "inbound" or "outbound."
