Webex Call App (MS Teams applet) available in Microsoft Teams for Caling in Webex App (UCM) (and may include Webex Calling or other PSTN uses) needs an e911 button like in the full Webex App client as used when registered to UCM.
When UCM is the calling engine used within the MS Teams applet, UCM will be responsible for the Emergency Services Calling and therefore needs to comply (in the United States) with the RAY BAUM'S ACT.
The recently added functions in the Webex App (for Windows and Mac) when using Calling in Webex App (UCM) complies with this, however, at this time if using the Webex Call (MS Teams) applet, combined with hiding the Webex App in the user's system tray provides no access to the e911 status and location entry windows.
The Settings button included in the interface for the Webex Call applet for MS Teams does launch the Settings window of the hidden Webex App client.
I understand that a Voicemail button (for Unity Connection visual voicemail), also not currently available, is in the roadmap for this Webex Call applet in MS Teams.
We need the insertion of the e911 status and location entry button included in the Webex Call app for MS Teams interface when Webex App is responsible for routing calls on behalf of the MS Teams user.
For feature equivalency in using the Webex App engine within the MS Teams interface, we need both the Voicemail and E911 buttons to be added so users can input their location when not detectable by the previously associated IP gateway MAC address.
