Multi Device Access

Last Updated : Feb 10, 2015 |

With the Multi Device Access feature, a SIP user can register multiple SIP endpoints with the same extension. You can specify the maximum number of SIP endpoints that can simultaneously register and receive calls in the Max. Simultaneous Devices field of the Session Manager communication profile section on the User Profile page. The default is 1. For more information, see Avaya Aura® Multi Device Access White Paper on the Avaya Support site at http://support.avaya.com/.

If the number of registration requests exceed the administered limit, and if the Block New Registration When Maximum Registrations Active field is:

  • Cleared, the system accepts the new registration and unregisters the endpoint with the oldest registration. If the endpoint with the oldest registration is active on a call, the system waits for the call to complete before unregistering.

  • Selected, the system denies any new registrations and sends the 403 Forbidden response with an appropriate warning header to the registering device.

The system routes incoming INVITE requests or call attempts to all the registered devices for a given user simultaneously. When the caller answers the call, the system cancels the INVITE request to the other devices.

The system routes an incoming CANCEL request to all the registered devices if the caller hangs up before the call is answered.
