> Most of that industry is still at "press 1 for sales, 2 for billing..." and needs something that will run locally on a 1U server.

Needs? Customers want something that immediately answers their question/solves their problem, but that’s far away, even ignoring the “run locally on a 1U server” and that that may not be in the company’s interest.

For many companies, that support line is a cost center, not a PR mechanism.

Also “Press 1 for sales, 2 for billing...” has the big advantage that it handles all accents, speech impediments, etc.

Long term I think a solution where a user’s agent trained on their voice, running on their phone communicates with the support agent of a company is where we will end up, and support phone lines will cease to exist.
