Voice mails have been stored on tape drives, hard drives, flash drives, etc since forever....
Yep. I would also imagine the DNC has a VoIP phone system.
I would tend to think it is some kind of VOIP system. And the voice mails are being stored on a server.
VoIP is all about the transmission medium where you use your Internet service to send and receive telephone calls. Interestingly enough, this is what your telephone company does with your calls anyway. The difference is where the data stream gets digitized.
The big question is whether the DNC recorded all their calls or not. If they did this could be the political equivalent of planting Eucalyptus all over the hills in Southern California. They are very useful for holding hills in a dry environment. But when they burn, they burn BIG and spread fast.
