I've found a way to offer a call on dm

func (cli *Client) OfferCall(callTo types.JID, video bool) error {
	clientID := cli.getOwnJID()
	if clientID.IsEmpty() {
		return ErrNotLoggedIn
	}
	var offerLen uint8 = 6
	if video {
		offerLen++
	}
	callID := strings.ToUpper(hex.EncodeToString(random.Bytes(16)))
	plaintext, dsmPlaintext, err := marshalMessage(callTo, &waProto.Message{Call: &waProto.Call{CallKey: random.Bytes(32)}})
	if err != nil {
		return fmt.Errorf("failed to marshal call: %w", err)
	}
	destinationNode, includeIdentity := cli.encryptMessageForDevices(context.TODO(), []types.JID{clientID, callTo}, clientID, callID, plaintext, dsmPlaintext, nil)
	if includeIdentity {
		destinationNode = append(destinationNode, cli.makeDeviceIdentityNode())
	}
	offerContent := make([]waBinary.Node, 0, offerLen)
	offerContent = append(offerContent,
		waBinary.Node{Tag: "audio", Attrs: waBinary.Attrs{"enc": "opus", "rate": "16000"}},
		waBinary.Node{Tag: "audio", Attrs: waBinary.Attrs{"enc": "opus", "rate": "8000"}},
	)
	if video {
		offerContent = append(offerContent,
			waBinary.Node{Tag: "video", Attrs: waBinary.Attrs{"orientation": "0", "screen_width": "1080", "screen_height": "2340", "device_orientation": "0", "enc": "vp8", "dec": "vp8"}},
		)
	}
	offerContent = append(offerContent,
		waBinary.Node{Tag: "capability", Attrs: waBinary.Attrs{"ver": "1"}, Content: []byte{1, 4, 255, 131, 207, 4}},
		waBinary.Node{Tag: "destination", Content: destinationNode},
		waBinary.Node{Tag: "encopt", Attrs: waBinary.Attrs{"keygen": "2"}},
		waBinary.Node{Tag: "net", Attrs: waBinary.Attrs{"medium": "3"}},
	)
	return cli.sendNode(waBinary.Node{
		Tag:   "call",
		Attrs: waBinary.Attrs{"id": cli.GenerateMessageID(), "to": callTo},
		Content: []waBinary.Node{{

hi is this possible to send call for only like 5 second
or X second 1, 2second ?

That doesn't work

My client sends the package but nothing returns from the server

14:10:08.046 [Client/Send DEBUG]
<call id="3EB0096894E2F3735674B5" to="xxxxxxxxx@s.whatsapp.net">
