Once the Rest API has been configured, MCS will automatically provision teleworker SIP extensions on the MBG.
The MCS will provision any SIP extension that has had the 'Use remote authorization credentials' setting configured against it:
To instigate the MCS provisioning of a SIP extension on the MBG, navigate to the 'Configuration -> Site Settings -> Phone Systems -> [Your PBX Name]' page. Edit the required SIP extension and then check the 'Use remote authorization credentials' check box. The MCS will pre-populate the remote authorization name and password with random values. Pressing save will update the credentials stored for the extension and will start the teleworker provisioning process.
To un-provision a SIP extension from the MBG, follow the provisioning process but uncheck the 'Use remote authorization credentials' check box. Once save is clicked it will instigate the MCS removing the SIP User from the MBG.
