Re: How to make two calls and connect them based on supervision of first call

Hi Tamara

You definitely don't have a 08/15 scenario there. I don't think you'll get
your initial design working.. the only way you can have B, C and D in the
same call is using a conference and I'm not sure which CLID B would get to
see in that case.. but I suggest that you quickly try this manually just to
make sure. I know that conferences are internally signalled with name
"Conference" and that the DN you'll see on the phone is the DN of the line
the call comes in.. so definintely nothing useful at all.

Unfortunately, your second scenario wouldn't work either because as soon as
C leaves the call, B should imho see the CLID of D (also to be verified.. I
only tested this will all PBX parties).

There is an approach that comes to mind that doesn't require any CTI, but
I'm not sure it's available in the Cisco environment: Certain PBXs can
change CLID during call routing and show the caller whatever CLID you'd
like. But as I said I have no idea if this works in the Cisco environment, I
only know this from Alcatel.

There are potentially other scenarios using redirects or routing functions
which allow you to modify the caller ID. You can redirect and change the
CLID, but I'm afraid redirect only works with calls that have not yet been
picked up. Then there is routing via Routepoint, but there again you can
basically route calls before they've been picked up.

Just one thing: in your original scenario.. you realize that B would see the
CLID of your CTI Port while the message is being played, right? And I'm
wondering if it's possible to change the CLID presentation during a call at
all (also to be verified with an on hand scenario).
