dfrear,
Alright, I had a chance to look into this a bit and I just realized that the only way to do it with just your system is not going to be possible with what you currently have in your system.
The problem is that the call has to be answer prior to being able to conference. What I was suggesting is that you send it to a location that would allow a conference IF it would answer, but that doesn't work as it won't answer and if it did then it wouldn't go to the Voice Processor; because it was answered, grrr.
The only way I can think to setup a conference without it being answered by the other side is via a trunk port; because the trunk actually answers in reality. If you had a Dual T-1 card installed then you could set it up to route calls between the two T-1 ports and have the answer port for all of the trunks be the Call Routing Announcement.
Otherwise you will need an external device like a RAD, multiple RADs really, or a multi-port IVR, or external voice mail setup to answer calls via SIP or Analog Trunks/Ports that will play your message and then hang up.
Sorry,
TE
