Enabling the router to treat DISCONNECT messages with PI 8 as standard DISCONNECT messages
When the router receives a standard DISCONNECT message, it brings down the user-side B-channel, sends a RELEASE message, and disconnects the call. When it receives a DISCONNECT message with Progress Indicator (PI) 8, it brings up the B-channel to receive in-band information. The device does not disconnect the call or release the B-channel resource until it receives a standard DISCONNECT messages.
To avoid unnecessarily occupying the B-channel resource, enable the device to treat DISCONNECT messages with PI 8 as standard DISCONNECT message.
