[Asterisk-Users] On Hold - Talked about before

[PBX]

Ok - Here is where I am at.  I know this topic has been discussed
before, but never a solid answer was set in place.  Is anyone aware of
any phones that can put a caller on hold and the caller hear MOH by the
user pressing the hold button.  I understand most phones are only muting
the speaker and handset.

I need to find a solution for this either this way or by implementing
something in ADSI.  But I have been unable to find any type of HOLD
pattern in ADSI.  A user can park the call and that in it self has
benefits.  But if a user just wants to put a caller on hold and then
come back and retrieve the caller from hold by hitting the hold button
again - how is this done?

And this has nothing to do with transfering the call.  I want the user
to be able to press "A" hold button and hang the phone up and the caller
hear MOH.

If any one can point me in the right direction that would be great.
