We struggled with this and eventually integrated our switch with Speedeon Data. They have a disconnected number scrubbing API. We sell it as an additional feature to customers who are interested in knowing when numbers are disconnected.

And if so, do there exist established mappings for them to SIP? I've never seen this present from any SIP termination gateway. As far as I know, disconnects are expressed in in-band audio service announcements fed backward via early media, followed by a rather generic SIP negative final response and reason. However, I'd be remiss not to ask!
