FXO Call does not drop after plying IVR

Hello Everybody,

I have got tired & fedup for fixing the below common problem :

FXO Lines does not disconnect after playing IVR from CUE & ThirdParty Contact Center

I am having CME 9.1 connected with HQ through SIP Trunk. In HQ i am having CUCM 4.1 integrated with Altitude Contact Center Solution. Altitude is having IVR which plays the Welcome prompt for company.

I am having FXO Lines on CME. When i call from my mobile to the IVR of Altitude System & i drop the call from mobile, my FXO channel remain off-hook for 5 - 10 min & if i call to the CUE IVR (which is installed in my CME) the call disconnects in 20 - 30seconds

I searched alot on this issue & i got many solutions, i tried them as well but no luck for me. If any body can help me will be highly appreciated. following is my config:

I tried by configuring " supervisory disconnect anytone " it worked but it is droping call randomly while listening the prompt.

I tried configuring timeout call disconnect 3 & timeout wait-release 3 still no luck
