asterisk users - Sep 2004 - Proposal regarding the "*80" vertical service code

I can't seem to get *80 to do its thing on a Zap channel.  Looks like
*8 is being seen by asterisk first, and *80 is basically inaccessible.
 What *80 is intended to do, by the documentation on the wiki and by
inspection of the source code, is add the last callerid to the
blacklist.

Looking at the source, I see the same behavior coded in chan_zap,
chan_mgcp, and chan_skinny.  While *8 isn't hard-coded here, it does
seem to be hard-coded in res_features, or at least has the default
pickup extension defined there.

Looking at the non-asterisk-specific CLASS/VSC page on the wiki, the
normal behavior of *80 is defined as "Selective Call Rejection
Deactivation", which doesn't seem to jive with asterisks intended *80
behavior.  On the other hand, *60 is defined as "Selective Call
Rejection Activation," which does seem to make some sense...

Given the above, wouldn't it make sense to move this feature to *60? 
It wouldn't be 'blocked' by the default call pickup extension, and
it
would align more logically with the standard VSC definitions...
