I have a BCM400 that's not releaseing the call quick enough and my IVR is still seeing the call as active. I have the Trunk mode set to "Supervised". Its taking approx. 30sec for the call to drop. Are there any other settings within the BCM that can be changed other than "Trunk Mode" to have the system disconnect sooner. I've been unable to locate a patch for this issue. Please advise
