Lack of user feedback in regards to webrtc phone

[alepolidori]

Steps to reproduce

• stop janus-gateway service
• no visual feedback is provided to the end-user, but only the white color of the web phone on top bar
• no feedback also for the web phone reconnection

Expected behavior

Whatever bad situation happen, a warning message has to appear on the front-end client, to inform user of the fact that he does not make a phone call anymore. Phone call is a crucial feature, so it has to be clear to the end-user what is happening.

Actual behavior

There is a very bad lack of information in regard of web phone problems.

Components

NethCTI Client: nethcti3

Covered scenario:

• stopped/restarted janus-gateway service
• webphone registration failed
• webphone disconnection/reconnection
• cti server restart/reload
• asterisk stop: this scenario is not managed. Janus webrtc continue to be online, no feedback is provided to the end-user who is able to make new calls which do not work. Also after asterisk restart some problems may arise on webphone. So new issue 5765 has been created.

A full-colored icon show the webphone status.
Each time the webphone is reconnecting or have a problem, the following feedback is provided to the end-user:

• a loader on the webphone icon into the top bar will appear
• the webphone icon into the top bar will change its color
• a popup will be shown under the webphone icon into the top bar
• the title of the browser will be changed blinking until the webphone has been registered correctly or the user has closed the popup
• if the cti app is in background also a permanent desktop notification will appear:
  • the user can close it
  • it is automatically closed if the webphone has been registered correctly
  • the user can click it to immediately show the cti app in foreground

Some graphical feedback status are:

• online webphone:
  
• busy webphone:
  
• offline webphone: (this is a condition to be shown to the end-user because the webphone is a crucial feature)

a popup

favicon modified

dekstop notification

all the showed feedback for offline webphone can be closed and are automatically closed if the webphone can register correctly.
Desktop notification is showed only if the cti page is in background.

Only aesthetics note: after logout, login page title starts to flash like when webrtc is not connected.
