GIR recording problem

Hi

We have a recording problem. This is exactly MOH issue.
If you listen to the recorded file after the call is finished, the silence is saved from the beginning, but the sound is recorded from the moment after press the hold button(Music On Hold) on the phone.
What settings cause this problem? I want to record from immediately after connecting the agent.

Below is a list of currently installed program versions.

 -------------------------------------------
      Resource Manager : 8.5.185.01
      Media Control Platform : 8.5.185.34
      SIP Server : 8.1.102.69
      Stat Server : 8.5.108.15
      Recording Processor Script : 8.5.070.64
 -------------------------------------------

Thanks
