3.9.6.4 Secondary Target Timer Expiry

  • Article

This section follows the product behavior described in endnote <67>.

When the secondary target timer expires, all existing transactions MUST be cancelled. If the enablecf flag is set, the call MUST be routed to the target specified in the forwardto list and the call forwarding timer MUST be started. If the enablecf flag is not set, the call MUST be forwarded to the user’s voice mail, if one is configured by setting the Request URI field to the user’s voice-mail-gruu as defined in section 2.2.3.
