Hello
@mohamed.tahon,
In case you're still struggling with this dialer, you can consider
SIP Caller as a replacement. This is a cloud based outbound call dialer which seamlessly integrates with your 3CX system. The integration is straightforward, you just need to define an extension in your 3CX server, and SIP Caller will connect remotely and make the calls you need. Calls will be made to external numbers, and you can transfer them to the queue, so the next available agent takes it.
In addition, SIP Caller provides a bunch of very useful features. As I see that you're sending these calls to live agents, the answering machine detection is a feature that you will love, and
will save you a lot of money. SIP Caller performs real time speech analysis to identify if the answering endpoint is a human or an answering machine, and lets you execute different actions depending on that. So for example, you can leave a message when a voicemail picks up, and transfer the call to your queue when a human is on the other side of the line. This will drastically improve your agents productivity, which translates to more money in your pocket.
Feel free to contact me in case of being interested in giving this a try.
