AlphaCom SDK Stentofon.AlphaCom - Call Reqeuest Handling

About the application

Config

The application is a Windows Forms project with two Forms, the Main Window and Config window for inserting the IP address of the AlphaCom. The application config file is the default config file for the Stentofon.AlphaCom.AlphaNet.dll named Stentofon.AlphaCom.AlphaNet.xml defined in the namespace Stentofon.AlphaCom.AlphaNet.Config.

If no config file at startup the application will open the config window. The config window can also be opened by clicking the 'Config' button in the Main Window.

Application Initialisation

The AlphaNetClient object is initialized with the AlphaNetClientConfig object containing the IP address etc. The AutoDiscoverAllNodes, AutoGetStationState and AutoSyncCallRequests properties is also set to get all StationState objects, and sync Call Requests:

_client = new AlphaNetClient(_formConfig.ClientConfig) { AutoDiscoverAllNodes = true, AutoGetStationState = true, AutoSyncCallRequests = trus };

All The StationState objects will be stored in InMemory structure using the Stentofon.AlphaCom.Data.dll:

_stateStorage = new AlphaComState(AlphaComStateStorages.IN_MEMORY);

Handlers For TCP Up/Down, Node Connection Up/down, StationState, StationBusy/StationFree, StationConnect/StationDisconnect is registered:

_client.OnTCPConnectionUp += HandleTCPUp;
_client.OnTCPConnectionDown += HandleTCPDown;
_client.OnNodeConnectionUp += HandleNodeUp;
_client.OnNodeConnectionDown += HandleNodeDown;
_client.OnStationStateReceived += HandleStationState;
_client.OnStationBusyReceived += HandleStationBusy;
_client.OnStationFreeReceived += HandleStationFree;
_client.OnStationConnect += HandleStationConnect;
_client.OnStationDisconnect += HandleStationDisconnect;
_client.OnCallRequest += HandleCallRequestReceived;
_client.OnCallRequestRemoved += HandleCallRequestRemoved;
...

Do the connection:

try{
_client.StartListening();
_client.StartMonitorThread();
}
catch (Exception ex){
connected = false;
}

Storing State info

Adding or updating on a StationState messages:

if (_stateStorage.UpdateStation(st) > 0) // If added
_registeredStationCounter++;

Update the station busy flag in the state storage on StationFree Message received:

var station = _stateStorage.GetStationState(sf.Station);
if (station != null)
station.SetBusyState(false); // Update the state storage object


Add a CallRequest: _stateStorage.AddCallRequest(cr);

Remove a CallRequest: _stateStorage.RemoveCallRequest(cr);

Retrieving StationState and CallRequest objects

Get a list of StationStates objects matching the Display Text or Directory number (if string is numeric):

var stList = GetStationList(textBoxStationSearch.Text);

Get a list of CallRequest objects on Directory number:

var callRequestList = _stateStorage.GetCallRequestListOnReceivingStation(_selectedStation.DirectoryNumber);
