Hi Leonid,
Finally I found the RTF configuration file is under c:\ProgramData\Dialogic\HMP\cfg on Windows 2008 platform, I have changed the file according to your suggestions, attached you'll find the logs captured for the scenario with two IPM_demo applications running on the same host, instance #1 (ipmB1C1, dxxxB1C1) makes the play of the file, instance #2 (ipmB1C2, dxxxB1C2) makes the recording.
I am not sure I have disabled info level on the latter two subsystems, I mean I changed the state of INFO to 0 after an initial test with 1, but I am not sure I have reloaded the config with the rtftool :-), anyway in case you'll see just some additional messages I assume.
Regards,
Alberto
