Tones

The N2IWF can be configured to request that the switch play a tone during a billing interaction for monitored CAMEL/INAP calls.

Tone configuration consists of selector rules defined in the TONES LogicApp service global variable.

<global name="TONES" type="array">
    <rule tone="1" var="bearer" value="voice" />
    <rule tone="0" var="bearer" value="video" />
</global>

Each rule may specify whether a tone should be played (or not). Rules are applied in the order listed until a match is made. If no rule applies, or none are configured, the LhoScpApp SSP parameter default_release_tone will apply.

Note that these tones are only used when the final grant of a call is made, i.e. when the OCS has returned Final-Unit-Indication or the rule action selected is grace.
