[Asterisk-Dev] PRI/T1-Signaling

The CAUSE element is only significant in DISCONNECT messages.
My proposal allows to send ANY kind of PRI / ISDN message.

One application would be to be able to send USER-USER messages during
Like sending a display message "Welcome to Asterisk-PBX" on incoming calls.
It would only be shown on ISDN equipment though.
Or to notify the user on the other end of a new CALLED_NUMBER when the call
got transferred to another extension.
I don't know how good the upstream switches are going to handle these
messages, but it leaves lots of room for experiments.

Does not this already exist, tho not documented?  By setting
PRI_CAUSE before calling Hangup?
