When the dual-mode device is in the Wi-Fi range, the embedded dual-mode client registers remotely over SIP to Session Manager to receive calls. When the dual-mode device is not in the Wi-Fi range, the dual-mode device uses the EC500 feature to receive calls.
Note:
The Exclusion feature does not work on Avaya one-X® Communicator for Mac OS X phone in SIP Dual Mode.
From Communication Manager Release 6.3.6, this feature extends to CES users as well and is also known as EC500 Call Suppression. When a call is made to a SIP extension that uses a dual-mode mobile client and has a CES profile associated with it, the SIP extension receives two calls: a SIP call and a cellular call. The SIP extension shows an incoming SIP call for initial one to two seconds. Before the user accepts the call, the SIP extension receives a cellular call from Communication Manager. With the introduction of EC500 Call Suppression feature, the dual-mode client applications, such as Avaya Workplace Client for Android, receive only a single incoming call on the mobile phone for that particular extension. EC500 Call Suppression ensures that users receive an alert either by a VoIP call or a cellular call, but never both.
The following scenarios show the real-time application of EC500 Call Suppression. These scenarios require remote access.
  • You are commuting and have configured the application to use the EC500 service. Also, you do not have Wi-Fi or cellular data access to Avaya Aura®. In this case, the EC500 service redirects all incoming calls on the deskphone to the mobile phone network.
  • After you reach home, you can connect to the home Wi-Fi network and use the VoIP service. You continue to receive all incoming calls directed to the deskphone on the mobile phone by using the home Wi-Fi network over SIP. In this case, the server suppresses the EC500 cellular call to the mobile phone based on the use of VoIP.
  • After you reach home, you can connect to the home Wi-Fi network and use the VoIP service. You continue to receive all incoming calls directed to the deskphone on the mobile phone by using the home Wi-Fi network over SIP. In this case, the server suppresses the EC500 cellular call to the mobile phone based on the use of VoIP.
