@AiCallYu_JuanS.
I'm sorry to hear that you're experiencing issues with the call transfer between agents. To assist you better, I'll need a bit more information about your setup. Could you please provide details on how the agents are connected and the method you're using for transferring calls? Additionally, it would be helpful to know if you're receiving any error messages or if the call simply drops. Once I have more context, I'll do my best to help you resolve this issue.
