15 HMR Configuration

Header manipulation rules (HMRs) use Oracle Enterprise Communications Broker-specific controls and/or REGEX to identify information in signaling messages the user wants to change. These rules get applied to Communications Broker agents, and operate globally on all applicable signaling traffic that reaches that agent. This section provides instructions on configuring HMR on the Communications Broker GUI interface.

See the Header Manipulation Appendix in this guide for full explanation of how HMRs work. This appendix is provided for those with no prior experience with HMRs. HMR configuration errors can adversely impact all of an agent's traffic. Be fully confident about the intent of an HMR, and review your HMR configurations carefully before activating them.

Note:

When outbound number translation is enabled, Communications Broker applies translation to SIP headers (Request-URI, optional From header, and To header) before executing outbound header manipulation rules. As a result, SIP header manipulation (HMR) operates on the translated header values. This behavior follows the same precedence as existing Request-URI and From header translation.
