I'm not aware of anything apart from saving channels...

Passing the original callerID during a forward/unattended transfer is
standard North American functionality... Call comes in, forwarded out either
over the same, or alternate, trunk, callerid left intact... A feature that
can make using certain commercial PBXs in other countries somewhat
problematic...

Updating the caller information during a call, including feeding back
connected callee information, is I believe, a qsig/dpnss addition used
within a private network (though there may be instances that it can work in
a public network that I've not seen)...
