Hi, The CDMA voice call manager interface is missing the line identification and start time property. The MO and MT calls will have LineIdentification, which should be set to empty when the call loses the LineIdentification. We will emit the property change whenever there is a flash sent. Example cases: 1) Outgoing call to number "123" LineIdentification = "123" 2) Incoming Call from Number "234" LineIdentification = "234" 3) a) Outgoing call to number "123" LineIdentification = "123" b) Flash to number "345" LineIdentification = "" 4) a) Incoming call from number "234" LineIdentification = "234" b) Flash to number "345" LineIdentification = "" 5) a) Outgoing call to number "123" LineIdentification = "123" b) Flash with empty string LineIdentification = "" 6) a) Incoming call from number "123" LineIdentification = "123" b) Flash with empty string LineIdentification = "" Similarly for StartTime, for a normal outgoing and Incoming call, we have StartTime values. But the issue is with Flash with String, where we cannot have the Call start time for the number which is sent as flash string. If a UI needs to show the call time for the flashed number, it cannot be decided by oFono. Example cases: 1) Outgoing call to number "123" StartTime = xxxxx 2) Incoming call from number "123" StartTime = xxxxx 3) a) Outgoing call to number "123" StartTime = xxxxx b) Flash to number "234" No separate StartTime for "234" , and no property change emitted. 4) a) Incoming call from number "123" StartTime = xxxxx b) Flash to number "234" No separate StartTime for "234" and no property change emitted. We also need a SetProperty() API. void SetProperty(string property, variant value) Changes the value of the specified property. Only properties that are listed as readwrite are changeable. On success a PropertyChanged signal will be emitted. Possible Errors: [service].Error.InvalidArguments [service].Error.DoesNotExist The following patch adds the above changes to document. Regards Arun
