Tone Rules

When the OCS returns Final-Unit-Indication or the Result-Code rule action or billing bypass action selected is continue_period at an initial or interim interrogation, the application can be configured to enable or disable the alert tone sent as part of the CAMEL ApplyCharging message in the aChBillingChargingCharacteristics → timeDurationCharging → releaseIfdurationExceeded → tone parameter.

Each rule may specify whether a tone should be played (or not). Rules are applied in the order listed until a match is made to the received value. If no rule applies, or none are configured, the SSP model default_release_tone will be used to set tone.

Configuration Details

Each rule can support the following attributes:

Attribute	Type	Description
`tone`	Boolean	[Required] Whether to enable or disable the tone for this rule.
`tag`	String	[Conditional] The tag name to match the value for If `tag` is present, `value` must also be present.
`tag_x`	String	[Conditional] As for `tag`, but with `x` representing a unique pairing, e.g. `tag_1` or `tag_a`. A matching `value_x` must also be present.
`value`	(various)	[Conditional] The string or integer value to match against during rule selection. Required when `tag` is present.
`value_x`	(various)	[Conditional] As for `value`, but with `x` representing a unique pairing, e.g. `value_1` or `value_a`. A matching `tag_x` must also be present.
`originating`	Boolean	Whether this rule applies for originating calls. (Default: `true`)
`forwarding`	Boolean	Whether this rule applies for forwarding calls. (Default: `true`)
`terminating`	Boolean	Whether this rule applies for terminating calls. (Default: `true`)
`at_initial`	Boolean	Whether this rule applies at the initial OCS interrogation, i.e. the Diameter `CC-Request-Type` is `1` (`INITIAL_REQUEST`). (Default: `true`)
`at_update`	Boolean	Whether this rule applies at interim OCS interrogations, i.e. the Diameter `CC-Request-Type` is `2` (`UPDATE_REQUEST`). (Default: `true`)
(other available fields)	(various)	Any number of selector rule available fields.

Note that, unlike other selector rules, the selector at_terminate is not permitted, as no Diameter Final-Unit-Indication can ever be present in this message.
