Session Summary (Voice Messaging)

This method allows you to review the "Voice Session Summary" status and individual call legs.
"Voice Session Summary" (VSS) endpoint. Your "Voice Session Summary" (VSS) endpoint can be configured on the sub-account level with the Voice Call Action Webhooks
This can be used alongside or instead of the Call Status, to simplify your monitoring.

startTime	String	Start time of voice messaging session
endTime	String	Start time of voice messaging session
lastAction	String	Shows the last executed command during the session
callCount	Integer	Shows how many call legs have been bridged for the given session
details	Object	JSON object containing information about all call legs in the session
callId	String	Unique identifier of call leg
callDirection	String	Indicates the direction of the call leg (INBOUND or OUTBOUND)
callType	String	Type of the call leg. Values can be "PSTN" or "VOIP", depending on where the call was initiated from (telco operators or VoiceSDK users). For Voice Messaging the value will always be PSTN.
initiatedTimestamp	String	Initiated time of call leg
connectedTimestamp	String	Time when the call leg is connected
disconnectedTimestamp	String	Time when the call leg is disconnected

destinationFormat	String	The value for Voice Messaging will always be "MSISDN"
sourceCountryCode	String	Country code for the Source Number
destinationCountryCode	String	Country code for the Destination Number
sourceRefId	String	For OUTBOUND call legs, this property shows the referenceId of the Virtual Number that has been called. For INBOUND calls the value is null
callStatus	String	Call status of the call leg. The values can be: COMPLETED, NO_ANSWER, BUSY, CANCELED, FAILED
callDuration	Integer	Call duration of the call leg.
errorDetails	Object	JSON object containing information about all call leg errors in the session
errorMsg	String	The error details of the call leg
errorCode	String	Error code specified in the Error object
callQuality	Object	JSON object containing information about all call leg call quality indicators in the session
mos	Float	Mean Opinion Score (MOS) is a numerical measure of the human-judged overall quality of the call leg
packetLossRate	Float	The packet loss rate reflects the reliability of a communication network path.
