Interactive Voice and Video Response IVVR makes it possible to make voice calls and interact with the web. For example with DSPV you can check traffic, look up stock quotes, and check up on store pricing. This is absolutely amazing because with just a phone call you are able to check on local traffic and view a live stream of it on your mobile phone. It’s possible to actually interact with the web versus just use it. There is a great deal of potential and a huge future for this technology in my opinion.
