So the solution would be that the network does not send the progress indicator in the Disconnect message, or find a configuration parameter on the gateway so that it ignores the progress indicator, right?
I believe the first one will be not a viable option at all, no telco will change any important protocol compliance rule on a "per subscriber" basis.
Now forget your gateway for a moment and make a call on an imaginary phone connected to your PRI, after that call successfully answered let the called party hang up before you do. What you expect to hear? Sure, a disconnect tone... so you will put your phone on hook and the phone will send a disconnect immediately.
Your pri<->gateway<->asterisk should work the same, even if the gateway does not send a disconnect immediately the user who started that call will hang up at least when hearing the disconnect tone (good feedback for humans, no?) and asterisk will send a bye to the sip gateway then that one shall initiate a disconnect on the user side.
Check also if your gateway allow for customization to remap isdn/q.931 messages to sip.
Sorry, hope you will be able to understand because English isn't my native language.
