Cause code 1 (ISUP/ISDN), SIP 404. This is the canonical way. "Disconnected" versus "not in my translations, but on my number block" is a meaningless distinction. Technically you can send a 301/302 I think with a new destination (there's a similar way to do this with ISUP) but it's not widely implemented so number changed referrals typically stay in-band.

I ?would have thought 1 means that the number has no entry in a switch translation table, which is something logically distinct from disconnection. I suppose it depends on how LECs implement the state of affairs to which "disconnected" colloquially refers. ? -- Alex Balashov | Principal | Evariste Systems LLC 303 Perimeter Center North, Suite 300 Atlanta, GA 30346 United States
