After we installed the Talking SIP 3.15.8.0 and IVR CA 3.15.2 files according to the steps you recommended, we restarted Talking SIP Server with callsession to test. The result was that the phone was disconnected, charged and in the diversion section. It can be used as well. We have sent the call log as per the attached file, but another important problem for us is that there is a SQL Server that can only be used on the primary machine, while the secondary machine cannot be used according to the Screenshot that we have attached. We cannot mirror from the current server. But if you have steps we can do it over TCP/IP, please share it with us.
