Multiple Device Access

Last Updated : Jan 22, 2021 |

With the Multiple Device Access (MDA) feature, you can register up to 10 SIP devices with the same extension to transfer active calls between devices.

This feature is available only in an Avaya Aura® environment. Multiple Device Access is configured on Avaya Aura® Session Manager.

MDA limitations

There are limitations for Multiple Device Access as Avaya J129 IP Phone supports only two call appearances, while the user might have more than two call appearances configured.

The limitations for Multiple Device Access are the following:

  • There is no audio or visual alerting for the third incoming call if two call appearances are already in use.

  • The Avaya J129 IP Phone will not display the third or higher call appearance.

  • When you receive an MDA indication, press the Phone button to view the details and join the bridged call.
