I'm in the process of having to come up with a solution to some of my sites conferencing issues. My main issue is I need the ability to "Blast Dial" multiple directory numbers (both on and off-site) upto 24 end users, and join them to a conference once they answer the call.
It looks like the Cisco Meeting Place had this option, but it is EOL, and not available any longer. We currently satisfy the requirement with an old TDM conferencing system that ties into our CUCM 8.6 cluster via T1CAS links. This equipment is very old, and need to be replaced. I would really like to see if there's some kind of work around within CallManager to make this work, or if that can't happen, what Cisco product will meet these needs?
There's a couple of 3rd party vendors that do offer this type of feature, Voiceinterop, XOP, TCCOM to name a few.
