I'm curious enough to ask (and I don't mean to sound snarky with this), but what's the value proposition?

If I'm a customer, what benefit do I gain from this? Phone numbers are easily recognizable and they're already in use. I'm going to have to fight with an IVR either way, and I can Google the number.

If I'm a business, I'm trusting a third party with my IVR to not disappear after 3 months of not making money, my agents aren't really seeing any improvement in customer connection (either through inhouse IVR or hallo, by the time the customer gets to me they should be at the right department). So how do I gain anything as a business by pushing my IVR to you?
