Retrieve call forwarding rules of a Lync client with server-side technologies (UCMA or MSPL)

Question

How can I retrieve the call forwarding rules (routing) of a Lync client in a Managed SIP Application (serverside technologies like MSPL or UCMA)? The only thing I found is an Ar

Answer 1

You cannot do it with an ApplicationEndpoint. You must have an UserEndpoint. However, you can create a UserEndpoint who just need the CollaborationPlateform and the SipUser and not any passwords.

For my application, I decompiled SEFAUtil.exe via ILSpy to understand how they did in their programs. I advise you to take a look at it.

This is my technique to make it works:

1/ Creation of the UserEndPoint

When creating the user endpoint you have to subscribe for this presence to get the information even if is not connected

userEndpoint.LocalOwnerPresence.BeginSubscribe(null, null);

2/ Subscribe to PresenceNotificationReceived Event

userEndpoint.LocalOwnerPresence.PresenceNotificationReceived += OnCategoryNotificationReceived;

private static void OnCategoryNotificationReceived(object sender, LocalPresentityNotificationEventArgs e)
    {
        // Here you get the PresenceCategory and all the data of the user
        foreach (PresenceCategoryWithMetaData current in e.AllCategories)
        {
            if (current.Name == "routing" && current.ContainerId == 0 && current.InstanceId == 0L)
        // Creation of your Routing, I stock it in a Property 
                _routingCategory = new Routing(current);
        }
        // I set my event to continue my main thread
        _routingCategoryUpdated.Set(); 
    }

3/ Display the information you want

 // Wait until you get the information of the user
 if (!_routingCategoryUpdated.WaitOne(10000))
        {
            Console.WriteLine("TimeOut Getting Informations");
            return;
        }
 // Just display all the data you can need
 else
        {
            Console.WriteLine($"User Aor: {userEndPointTarget.OwnerUri}");
            Console.WriteLine($"Display Name: {userEndPointTarget.OwnerDisplayName}");
            Console.WriteLine($"UM Enabled: {userEndPointTarget.UmEnabled}");
            Console.WriteLine($"Simulring enabled: {_routingCategory.SimultaneousRingEnabled}");

            if (_routingCategory.SimultaneousRingEnabled && _routingCategory.SimultaneousRing != null)
            {
                foreach (string time in _routingCategory.SimultaneousRing)
                {
                    Console.WriteLine($"Simul_Ringing to: {time}");
                }
            }
