[default]
; This section holds default settings for each of the following message handlers
; All these settings can be overriden in individual handler sections

; priority: int: Priority in Yate's handlers chain
;priority=50

; account: string: Name of the database connection to use
;account=


; In each of the following sections you have to specify the following:
; - initial query to execute when module is initialized
; - query to execute for each received message
; - result field to copy in message's textual return value (only for some)
; You can also override the settings from section [default]

; Sample queries below are for PostgreSQL
; Timestamps and intervals are unfortunately non-portable


[user.auth]
; Query and result name for the user.auth message
; The result must not be empty for password authentication to work
; The designated result field is mandatory in the columns to prevent a
;  configuration error from authorizing everybody. Use something

; Query for the timer message that expires registrations
; Also look at the expires setting in section [general]

[call.preroute]
; Query and result name for the prerouting message
