OPTIONS Operation
For Release 6.x, the sending of OPTIONS messages on a SIP line is controlled by a number of fields as follows:
· If either REFER Support or the UPDATE Supported values are set to Auto, then OPTIONS messages are sent.
· If neither REFER Support or the UPDATE Supported values are set to Auto, then:
· If the LAN interface's Binding Refresh Time is set, addition OPTIONS messages are not sent.
· If the LAN interface's Binding Refresh Time is 0, the sending of OPTIONS messages depends on the line's
Check OOS setting. If Check OOS is enabled, OPTIONS are not sent if line registrations occur more
frequently, otherwise OPTIONS are sent.
