About this Page

  • This document details how to configure the SBC to copy a value from the HISTORY-INFO SIP header into the Calling Number.
  • This document shows the creation of a SMM Rule Table that selects only certain SIP Messages for modification. In this case, only INVITE packets will be inspected.
  • This document details how to use the SMM feature copy a header value into one of the user-controlled IEs (SG User Value 1).
  • This document details how to copy a user-controlled IE value into the Calling Name IE using the Transformation Table.

Prerequisites

Requires Sonus SBC2000/1000 Version 2.2 or later

Moving the History-Info Number to the FROM Number

Normally, the SBC automatically maps History-Info into Redirecting Number; however, the automated mapping function works for specific reasons encoded in the History-Info header. In some cases, like Lync's forwarding feature, a reason is not present.

SMM may be used to map the History-Info to the FROM (or Redirecting) as detailed in this document.

The process entails:

  • Copy the contents of the first ordinal in the History-Info header to SG User Value 1. The first ordinal (in italics below) is considered anything before the comma which is used to separate the lineage (history) of the call.
  • A translation table copies a modified value from SG User Value 1 to the Calling Number IE.

Configure the SBC1000/2000 for Header Manipulation

  1. Create a SIP Message Rule Table.

    Figure : Create SIP Message Rule Table

     

  2. Add a SIP Message Rule to capture the first ordinarl of the History-infoheader using the Add Header selection.

    Figure : Add SIP Message Rule

     

  3. Add a calling number transformation to move the number from SV User Value 1 to Calling Number

    Figure : SG User Value 1
