Asterisk AsterNET How to move from parking to queue?

Question

Im using C# AsterNET to manage my Asterisk commands and events, and now I do have a new feature to work on.

This is simple (I think) but I'm stucked right now.

Scenario

I do have two queues, 8100 and 8300, and 2 extensions being 8101 and 8301. When I do have a call from PSTN it is driven to 8100 queue. When the 8101 extension become available I do add this extension to the 8100 queue, so the calling PSTN device will be redirected to this 8101 extension.

Everything is working fine till here.

Sometimes I do park the calling device and let 8301 knows it using my app, so 8301 user using the same app can send a command asking for that parked channel to be redirect to his SIP Phone. Also working fine.

Scope

Now I want to have some feature to let 8101 transfer this calling device to my other queue, the 8300. So I just tried to reuse my parked method and redirect method

internal void Park(string channel, int parkTimeout)
{
    ParkAction pa = new ParkAction(channel, channel, parkTimeout.ToString());

    ManagerResponse mr = manager.SendAction(pa);
}

internal void RedirectFromParking(string channel, string exten)
{
    RedirectAction ra = new RedirectAction
    {
        Priority = 1,
        Context = "default",
        Channel = channel,
        Exten = exten
    };

    ManagerResponse mr = manager.SendAction(ra);
}

Park("abc123456", 10000);

RedirectFromParking("abc123456", "8300")

Issue

I'm parking fine but when I try to redirect from parking to my queue the calling device is just disconnected and the connection is lost.

How can I transfer a parked call to my queue or transfer it directly to the queue (would be better) without needing to originate?

Just do hold instead of parking and make your own list of such calls.

Even holding the call I can't transfer it to 8300 queue. If I want to transfer the holding call I would need to originate from my SIP to 8300 queue like explained on other post https://stackoverflow.com/questions/48429244/asterisk-call-transfer-to-queue – Andrew Paes Sep 04 '19 at 21:08

To transfer to a queue I can do a blind transfer as documented on Asterisk website. Links below:

ManagerAction_BlindTransfer

ManagerEvent_BlindTransfer

To achieve this using AsterNET, I can use the same RedirectAction I was using but I do need to change the context. It can't be default for context, as default we are letting Asterisk manage it and somehow it can't handle as I expetected. So it need to be clearly specified as internar transfer. The event raised after this context transfer is the Manager_BlindTransfer.

Manager_Action_RedirectAction

So using my SIP Phone I manage to transfer a call while I was debugging that raised event method, so I could catch the context used in. Using the correct context

ManagerConnection manager = new ManagerConnection(address, port, user, password);

manager.BlindTransfer += Manager_BlindTransfer;

private void Manager_BlindTransfer(object sender, BlindTransferEvent e)
{

}

After this I created another method to transfer to directly to a queue using the correct context.

internal void TransferToQueue(string channel, string queue)
{
    RedirectAction ma = new RedirectAction
    {
        Priority = priority,
        Context = "from-internal-xfer",
        Channel = channel,
        Exten = queue
    };

    ManagerResponse mr = manager.SendAction(ma);
}

TransferToQueue("abc123456", "8300")

Summary

Was just a matter of the correct context to be used in.
