Enable Users to Make Calls even if Teams is Unavailable

A fallback feature enables users to make calls even if Teams is unavailable. If Teams is unavailable, the device will still have connectivity to the internet via the SBC using a SIP-based application.

For this feature to work, the SBC must be configured for WebRTC. For details, refer to the WebRTC section in the Mediant Software (VE-CE-SE) SBC User's Manual.

➢ To enable it, the administrator must:
1. Set parameter ‘system/ace/shortcut_enabled’ to 1 (default = 0); an AC soft button is then displayed in the lower right corner of the phone screen (if Teams is unavailable) as shown here:

➢ To register a SIP account (sign in), the admin must:
1. Set the following parameters:
● personal_settings/sip/server =wss://<SBC URL>
● personal_settings/sip/port =<SBC server port>, e.g., 443
● personal_settings/sip/domain =<domain name>
● personal_settings/sip/username=<account name>
● personal_settings/sip/password=<account password>
2. View the account status: Connected if registered, Not Connected if not registered.

➢ To enter the app, the user must:
■ Press the AudioCodes Smart button on the phone as shown below (only when parameter ‘system/ace/minilauncher_enabled’ is set to 1) to switch between Teams and the app.

➢ To add up to 41 speed dial keys, the administrator must:
1. Use the following parameters:
● personal_settings/functional_key/[0-40]/speed_dial_number= < destination>
● personal_settings/functional_key/[0-40]/type = DEFAULT (button retains its Teams color) -or- EMERGENCY (button is colored red)
● personal_settings/functional_key/[0-40]/display_name= <destination display name>

➢ To make a call, the user must:
1. Press the speed dial; the calling screen shows the callee’s name. To end the call, on-hook the handset or press the speaker/headset button.
2. View the phone’s calling screen:

3. View the phone’s incoming call screen:

4. [Optionally] During the call, the user can adjust the volume, mute, unmute, DTMF, switch audio source, etc.
● The app blocks incoming calls when Teams is in the foreground.
● When Teams is available and the app is in the foreground in idle state, the phone cannot get an incoming Teams call.
● After rebooting, the device always displays the Teams home screen.
