I have IPCC 4.5(2) and CCM 5.1.3
I have an application that have the trigger 5600.
Sometimes we call this application and it's busy. I know that there is enough CTI port available. I can confirm this with the real time monitoring GUI on IPCC.
I think there is a problem with the control group because... when I change the application to use another Control group, it fix our problem.
Also, with an IP Phone if I dial the 5600, if the application answer, I will see 5600 follow with the CTI port used. If it's busy, I will see only 5600 ( no cti port )
I would like to understand a little more about this problem. Is there somebody that can help me with this situation.
