[SIP Trunk]
• The necessary
account information for connecting the SIP trunk must be configured at the Backup Master
unit beforehand. This information is not automatically set from the Master unit.
• This feature can be used only between the Master unit and the Backup Master unit. If a SIP trunk is specified
as a backup at a site other than the Backup Master unit (including the Master unit), the setting is ignored.
