====== Message Waiting Indicator ======

For more information refer to the ACM integration documentation [[https://drive.google.com/file/d/1NYoEecXxidvJKyKeu3WUIvFAoVzF4827/view?usp=drive_link|here]].

===== Context =====

  * By default, the DuVoice integration to ACM uses SIP notify.
    * DuVoice will send SIP notifies to the Session Manager.
    * The Session Manager will route the MWI from there.

===== Issue =====

  * When the DuVoice server sends a SIP notify to the ACM:
    * The ACM (Session Manager) will respond:
      * ''404 Not Found - No Route Available''.
    * DuVoice logs will will report:
      * ''Notification Rejected''.

===== Fix =====

==== ACM integration ====

  * Within the Session Manager:
    * There must be dial patterns in place:
      * The DuVoice must be able to dial any extension that is using DuVoice for voicemail.
        * Example: **Pattern**: ''7XXX''
