Hi all,
 
in Germany we have the legal standard, starting 1.9 of Sepmtember this year, that the first 120 seconds of call should be for free for the caller, it least for some special numbers.
 
I have seen the slides from Paul Tindall on how to delay the connect in CVP. I guess with the slides and some testing, we could get this working. Or at least I hope so ;-)
 
What bothers me more is, that the caller will just hear ringback and will mostly hang up after 20 seconds, as he does not hear any announcment. My question is: am I able to play messages to the ISDN, befores sending the ISDN connect? Has anyone experience in doing that? With the command:
voice rtp send-recv
we can open the media channel in the receiving direction, but does it also work for sending?
 
I would like to have a custom  TCL and VXML to accept the call without connecting in UCCE/ICM. I will select an agent, but the meanwhile play a prompt using CVP.
 
Any advise, idea or suggestion is very much appreciated!
 
Cheers
Christian
