The PBX link is what DuVoice uses to forward name and COS updates to the IP Office.

Depending on existing settings, the PBX link integration may stop working.

  * **This is not supported by Avaya**. 
  * These DLL files are updated versions of those in the Avaya SDK distributed with DV2000 distribution to perform name changes. 
  * Avaya has never updated their SDK distribution since its release.
  * It is not known if the DLL's provided via IP Office Manager are backwards compatible, and therefore you should always use the version of IP Office Manager you used to manage your IP Office.
  * **This procedure must be performed each time the DV2000 is updated/upgraded.**
