Have you considered Cisco Conference Connection? Provides security for audio conferencing solution that integrates with Cisco CallManager. Refer to the docuemntation below:
Conference Connection to my knowledge has been End of Sale for some time and almost End of Support very soon.
Meeting Place Express has traditionally been my "cheaper" conference bridge solution.
Have not had any experience with 3rd party products but I am curious as well.
FYI - I think newer Call Manager Express has the option for passwords on meet-me but I have never configured that myself. That has always been a wish of mine for Call Manager to have a password for meet-me.
Yeah, CCC has been replaced with MPE, I can't tell for sure if there's a 3rd party out there, personally I haven't seen one. You can try finding a Developer Partner here:
I actually work for a company who deploys such systems. I am merely a consultant so unfortunately I am not sure on commercials e.g. pricing etc.
However I can provide some contact information if you would like.
Would you like me to email these to you? I presume your ID is valid?
