Who makes Voicemail Systems for Cellular Providers?

I'm working on a research paper about voicemail systems used by cellular providers. I'm looking for who the big providers are and what cellular providers use them.
Also, I'm interested in how these systems interact with the Mobile Switching Center. I believe most connect using SS7, but where exactly do the voicemail systems reside? Are they actually in the MSC or are they located off-site. I don't need specific addresses, just if they are on or off site.
I've been browsing the web for nearly two weeks now and just can't seem to find the kind of information I'm looking for. So, I'm hoping someone who either works on the voicemail systems, installs them or knows anything about them can help me out.
Thanks for anything you can provide.
