Session Translation

A session translation defines how translation rules are applied to calling and called numbers. Multiple translation rules can be referenced and applied using this element, which groups rules together and allows them to be referenced by one identifier.

The ESBC only applies session-translation and translation-rule processing to a limited number of out-of-dialog requests, including:

  • INVITE
  • CANCEL
  • REFER
  • OPTIONS
  • SUBSCRIBE

The ESBC does not manipulate any header within in-dialog requests using session-translation or translation-rules.

There are two parameters in the session translation element. The rules calling parameter lists the translation rules to be applied to the calling number. The rules called parameter lists of translation rules to be applied to the called number.

The ESBC applies the translation rules in the order in which they are entered. They are applied cumulatively. For example, if this field is configured with a value of rule1 rule2 rule3, rule1 will be applied to the original number first, rule2 second, and rule3 last.

To configure the session translation element:

  1. Enter a descriptive name for this session translation in the ID field.
  2. Enter the IDs of existing translation rules in the rules calling parameter. Multiple rules can be entered in this field. The order you enter them in is the order in which they are applied.
  3. Enter the IDs of existing translation rules in the rules called parameter. Multiple rules can be entered in this field. The order you enter them in is the order in which they are applied.
