Acejavelin,
What I figured out to do was create a 6940 with PKMs and set it to IP Device Only to use as a way to create Phantom extensions. I then would go to the Keys and setup single lines of extension that I didn't want as a full blown extension. Then I would go to the Directory and name the new single line and then on to Call Reroute to route it Always [Day, Night1, Night2] to Voice Mail. This way I can have a lot of PKM entries in one location to look up and manage.
What would the ACD Express Path provide you that the method I explained wouldn't be able to do; just curious in case I should switch to your method? Also, does it require a license for the ACD Express Path to work; I haven't used one on either system I worked on?
Thanks,
TE
