Use the Send All Calls (SAC) feature to redirect all incoming calls to a predefined extension when the Presence status is set to Do Not Disturb (DND) on your extension. Device Adapter does not support changing the Presence status to and from DND. However, you can change your status to DND on an Avaya Aura® SIP phone and later log in to the Device Adapter phone by using Sequential Registration.
On the Device Adapter phone, you can activate or deactivate the Send All Calls (SAC) feature when the Presence status is set to DND. But, you cannot change the already set Presence status (DND in this case) on the Device Adapter phone. However, you can sequentially log in to an Avaya Aura® SIP phone and change the Presence status.
Avaya recommends that you always change your Presence status to Available before registering to any other phone. For more information, see the Using Avaya 9608/9608G/9611G IP Deskphones SIP document.
