session.values namespace properties

At the start of a CCXML session, the Application Interface web service places several properties in the session.values.avaya namespace properties.

Property

Description

telephony.native_audio_format

The audio encoding codec the MPP uses as the default for audio recording within the Avaya Voice Browser (AVB) when the speech application does not specify the format for recording caller inputs.

The options are:

  • audio/basic: The AVB uses the mu-Law encoding format, which is used mostly in the United States and Japan.

  • audio/x-alaw-basic: The AVB uses the A-Law encoding format, which is used in most countries other than the United States and Japan.

fax_detect_enabled

For inbound calls, this property is set to the same value as the Fax Detection Enable parameter set for the application through the EPM web interface.

fax_detect_redirect_uri

For inbound calls, if fax detection is enabled, this property is set to the same value as the Fax Phone Number parameter set for the application through the EPM web interface.

ConnectTimeoutSecs

For outbound calls launched by the Application Interface web service, this is the maximum amount of time, in seconds, to wait for the CCXML application to be start before returning an error message.
