‎Hello,

Are there ISUP cause codes for disconnected numbers? 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!

Thanks!
