All improvements and fixes at a glance:

• The function for restarting the telephone system has been removed from the Admin interface.
  (Background: In the event of problems, restarts cause additional load on our infrastructure, especially if many systems reboot at the same time. If required, we can restart the telephone systems)
• You can now select several mobile devices in the end device list and send the e-mail for pairing to all associated users with one click.
• The SIP registration of Gigaset DECT gateways has been improved.
• In the REST API, the /connector/action endpoint has been given a "background attribute". This means that the job is executed in the background and does not wait for the return code.

Overview of all improvements and fixes:

• Grandstream gateways with model extension V2 (e.g. HT801V2) can be provisioned again. 
• SQL error when creating a private phone book entry fixed.
• Improved audio quality of uploaded announcements when listening in the browser. 
• The setup wizard now creates a default pause reason for new telephone systems (name: Pause)
• Indicator for running jobs in the Admin Dashboard improved. It is now more conspicuous.
