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 inband information. The router does not disconnect the call or release the B-channel until it receives a standard DISCONNECT message.

To avoid unnecessarily occupying B-channel resources, enable the router to treat DISCONNECT messages with PI 8 as standard DISCONNECT messages.
