I haven't heard of such a thing yet, but it doesn't sound 
tremendously difficult on a per-call (not per-channel) basis.

Cisco is including some rudimentary information in the SIP BYE 
messages these days, which I think will be emulated by other CPE 
hardware providers (hint, hint.)

I'd like to see something more comprehensive for all channel types.
